A four-year, NOK19.95m ($2.3m) program will see the tiny computer put into the hands of all year 5 to 7 pupils in Norway’s primary schools to stimulate interest in computing and the IoT

Nordic Semiconductor today announces that the ‘micro:bit’, a Nordic nRF51822 Bluetooth® Low Energy (Bluetooth LE) System-on-Chip (SoC)-powered, credit card-sized programmable computer for schoolchildren, will be distributed to 100,000 year 5 to 7 pupils in Norway.

A NOK19.95m ($2.3m), four-year program financed by Sparebankstiftelsen DNB, a Norwegian charitable foundation, will be administered by The Knowledge Center and Lær Kidsa Koding (LKK), non-profit organizations that teach children IT and coding skills, together with the country’s regional science centers. The micro:bit is also being made available to LKK’s 160 code clubs in Norway. The distribution will be accompanied by a training program for teachers and free online support.

The micro:bit was first developed by the British Broadcasting Corporation (BBC), a U.K. public service broadcaster, and key technology partners, including Nordic Semiconductor, Arm, Microsoft, and Samsung. It was designed to teach children coding skills and increase the number of students studying computer science at university.

“Nordic Semiconductor was pivotal in the original development of the BBC micro:bit and remains pivotal to its success to this day”  – Gareth Stockdale, Microbit Educational Foundation

Today, micro:bit is promoted by the Microbit Educational Foundation and is available to purchase from dozens of distributors across the world. The computer was distributed to a million ten and 11-year-olds in the U.K. in 2016, and 65,000 Danish schoolchildren in 2018. There are micro:bit activities in over 50 countries around the world and further national roll-outs are planned in Iceland and Croatia, among others.

“The micro:bit will provide a boost to programming education in Norwegian primary schools,” says Geir Endregard, Director of INSPIRIA, the organization responsible for the project on behalf of the country’s regional science centers. “Children in Norway will now get a common tool that will help strengthen the connection between several key learning arenas such as a science center, school, and leisure. We strongly believe in this unique link between formal and informal learning.”

“Nordic Semiconductor was pivotal in the original development of the BBC micro:bit and remains pivotal to its success to this day,” says Gareth Stockdale, CEO of the Microbit Educational Foundation and a joint lead on the original BBC project.

“Nordic has been part of the micro:bit project from its inception so it’s gratifying for all the company’s staff to see this latest phase of distribution – particularly in Nordic’s own home country,” says John Leonard, Product Marketing Manager with Nordic Semiconductor and responsible for the company’s educational initiatives. “As suppliers of Internet of Things [IoT] technology we are keen supporters of the micro:bit as a means to encourage the engineers we’ll need to build tomorrow’s connected world.”

At the heart of the micro:bit is a Nordic Semiconductor nRF51822 SoC. Code written by the children runs on the SoC’s Arm® Cortex™ M0 processor, and the chip’s Bluetooth LE connectivity allows micro:bits to communicate with each other or with a Bluetooth 4.0 (and later) smartphone or tablet.

Nordic has already donated over 3000 micro:bits to code clubs, schools, colleges, and universities in Norway in addition to 2000 of the computers previously given to LKK. Nordic was also among the original group that lobbied for a distribution program in Norway similar to that which had taken place in the U.K. The company supports micro:bit clubs and educational institutions in North America, India, China, and Japan. micro:bit is also used for undergraduate courses at The Norwegian National University of Technology and The Natural Sciences (NTNU).

Nordic’s nRF51822 is ideally suited for Bluetooth LE and 2.4GHz ultra low power wireless applications. The nRF51822 is built around a 32-bit Arm Cortex M0 CPU, 2.4GHz multiprotocol radio, plus 256kB/128kB of Flash memory and 32kB/16kB of RAM. The SoC is supplied with Nordic’s S130 SoftDevice, a Bluetooth 4.2 qualified concurrent multilink protocol stack.

u-blox CellLocate and hybrid positioning

Mobile network-based positioning

Benefits

  • Positioning performance can be improved and extended to areas where GNSS satellite signals are 100% blocked, especially within buildings
  • Eliminate “no‑fix” scenarios by providing at least an approximate fix wherever cell phone coverage is available
  • Overcome GNSS jamming scenarios to improve antitheft system performance

CellLocate® is based on hybrid GNSS and mobile network attributes. It provides increased location reliability and enhances GNSS positioning indoors.

Although GPS is a widespread technology, GPS positioning is not always possible, particularly in shielded environments such as indoors, enclosed park houses, or when a GPS jamming signal is present. The situation can be improved by augmenting GPS receiver data with mobile network cell attributes to provide a level of redundancy that can benefit numerous applications.

Based on internally developed cellular transceiver modules, u‑blox has embedded the cellular positioning technology CellLocate® into a number of its 2G, 3G and 4G modules. The technology  uses the CellLocate® service to  provide the modem with a location estimate, based on its observations of the surrounding cellular base station signals, assisting the GNSS receiver and providing a fallback positioning solution.

This improves positioning data in several use cases:

GPS signals are blocked: a GPS receiver cannot determine a position when satellite signals are unavailable, such as within tunnels, buildings, or metallic containers. For fleet and supply chain management or tracking of people inside buildings, this condition can be unacceptable. In this case, a cell‑based positioning system using GSM cell information can provide an estimated position. This is attractive for vehicle or container tracking applications where an approximate location of valuable assets is preferable to no position fix at all. This system is functional within warehouses, rail stations, airports, and tunnels.

GPS signals are jammed: GPS jamming devices are easily obtained for less than a hundred dollars. These devices can neutralize GPS receivers, and are often employed during vehicle theft. A backup cell‑based system in this case acts as a secondary system, as GSM cell signals are available even when satellite signals are blocked by jamming. The GPS receiver can also add intelligence to the system as u‑blox GPS receivers can detect when a jamming signal is present, putting the system into an “attempted theft” condition.

Machine‑to‑Machine (M2M) applications: Many M2M applications require positioning capability within a bounded area such as within a city, along main vehicle or rail links, or within specific venues such as an exhibition, entertainment or healthcare facilities. Positioning reliability in these areas can be improved by using cellular signals as well as GPS to provide accurate positioning. Based on an extension of u‑blox’ AssistNow Online GPS assistance service, u‑blox’ CellLocate technology is used to match cellular positioning data coupled with previously successful GPS fixes.

This “learning” solution can be practical for M2M applications where units are repeatedly used in specific areas such as a taxi fleet in a city, or containers and palettes travelling between warehouses. In these cases a specific database of useful cell data is quickly generated and the service is able to reliably give the current position to the user.

The above scenarios exploit the combination of Cellular and GPS positioning data (Hybrid positioning) to deliver better results than GPS technology could accomplish alone:

Positioning performance can be improved and extended to areas where GPS satellite signals are 100% blocked, especially within buildings
Eliminate “no‑fix” scenarios by providing at least an approximate fix wherever cell phone coverage is available
Overcome GPS jamming scenarios to improve antitheft system performance

Every Nordic Semiconductor nRF9160 Development Kit now ships with a globally-usable iBASIS eSIM to enable automatic and instant ‘out-of-the-box’ cellular LTE-M and NB-IoT connectivity and roaming in a long and growing list of countries with cellular IoT networks.

Nordic Semiconductor today announces that it has partnered with one of the world’s largest international cellular carriers in voice, data, and IoT services, iBASIS, to make global LTE-M and NB-IoT cellular IoT connectivity ultra-easy, automatic, and instant when using its nRF9160 System-in-Package (SiP) module.

Nordic has achieved this by bundling a globally-usable iBASIS eSIM with 10 MB of free initial data into all its nRF9160 Development Kits. All a Nordic nRF9160 cellular IoT customer has to do is register their eSIM on Nordic’s nRF Connect for Cloud website to seamlessly connect to the iBASIS ‘Global Access for Things’ network and gain access to an entire range of configurations, monitoring, and connectivity services.

Although it’s not common knowledge outside of the cellular communications industry, global smartphone connectivity and roaming services are actually provided by only a few international carriers that partner with local national carriers to enable connectivity and roaming for voice, data, and IoT services worldwide. iBASIS is one of the world’s largest international carriers or ‘IP Exchange providers’ and used by over 700 local carriers in over 190 countries.

As a result, Nordic’s nRF9160 cellular IoT customers get instant high-quality global connectivity without having to go through the ordeal of negotiating and managing multiple relationships with individual local cellular carriers around the world. Using eSIM technology, they simply leverage iBasis as a single global connectivity supplier, with a single contract, a single ‘operations’ on-line dashboard, and a single monthly bill that breaks down all global services used.

An eSIM is a remotely, over-the-air ‘provisionable’ (programmable) SIM that can hold multiple sets of local network operator credentials in contrast to a traditional SIM card that can only hold one set of operator credentials. The iBASIS eSIM meets all relevant GSM Association (GSMA) standards.

”We are reducing complexity, making it easy to support Nordic’s customers’ global deployment, using a single eSIM, for a remotely programmable on demand service.” – Ajay Joseph, CTO of iBASIS

The nRF9160 SiP – which is available from major global electronics distributors such as Digi-Key Electronics, Mouser Electronics, and Premier Farnell (amongst others) – is significantly smaller, lower power, and has more security features than any other cellular IoT module launched to date for LTE-M and NB-IoT applications. It is also certified for global operation, has a host of unique IoT-targeted features, and is dramatically easier to design-in (see ‘More about nRF9160 SiP’ below).

“iBASIS believes that for IoT to succeed, connecting things should be easy,” says Ajay Joseph, CTO of iBASIS. “We feel IoT connectivity should be turnkey, seamless, and secure. We’re delighted to partner with Nordic Semiconductor to provide an eSIM for Nordic’s nRF91 Series cellular IoT modules. We are reducing complexity, making it easy to support Nordic’s customers’ global deployment, using a single eSIM, for a remotely programmable on demand service. Nordic customers can focus on their core competencies knowing that their cellular IoT connectivity, coverage, speed, latency, and security are all being expertly managed by one of the world’s leading international cellular data carriers.”

“We designed the nRF91 Series from the outset to make cellular IoT easy and applicable to any application that would benefit from a cellular connection,” comments Geir Langeland, Nordic Semiconductor’s Director of Sales & Marketing. “For us, this extends to every aspect of the module’s operation and customer experience and that includes making international connectivity and roaming automatic and instant. In fact, I think for any IoT application to succeed its wireless IoT connectivity must be that simple. With the iBASIS eSIM, we believe Nordic Semiconductor has delivered this to its customers. It’s also why we believe cellular wireless technology is an ideal technology for building the Internet of Things.”

More about the nRF9160 SiP

At just 10 x 16 x 1mm in size, the nRF9160 SiP is suitable for even compact wearable consumer and medical devices yet is a complete solution that integrates everything a cellular connection and IoT application may need beyond requiring just an external battery, SIM, and antenna.

To achieve this ultra-high integration Nordic partnered with Qorvo to make a System-in-Package that more closely resembles an integrated chip than a module. The nRF9160 SiP leverages Qorvo’s state-of-the-art, proven RF front-end, advanced packaging, and MicroShield™ technology to deliver a unique, ultra-compact solution that combines high performance with low power consumption. The nRF9160 SiP supports global operation with a single SiP variant thanks to the combination of Nordic’s multimode LTE-M / NB-IoT modem, SAW-less transceiver, and a custom RF front-end solution from Qorvo.

In parallel, the nRF9160 SiP is the first cellular IoT module to incorporate Arm’s latest Arm Cortex M-33 CPU core. This is supported by 1MB of Flash and 256kB of RAM on-board memory. The nRF9160 SiP is also the first module to incorporate Arm’s state-of-the-art Arm TrustZone and Arm CryptoCell security for Internet-level encryption and application protection. Both these technologies are designed for highly energy-efficient embedded IoT products that require the highest levels of performance in processing, power consumption, and security.

The nRF9160 SiP has 1MB of Flash plus 256 kB of RAM on-board memory with a broad range peripheral set, analog and digital interfaces, 32 GPIOs, a stand-alone modem with full LTE capability, plus a multiband RF front-end.

Another unique feature of the nRF9160 SiP in the cellular IoT module market is integrated GPS support to allow a combination of GPS and cellular data to be used for more accurate positioning than either technology is capable of when used in isolation.

How the world’s largest Bluetooth chip supplier came to be in cellular IoT

Nordic Semiconductor is best known for its leadership (both commercial and technological) in the global Bluetooth® chip market. The wide availability of the nRF9160 SiP module marks Nordic’s official – but brand new – entrance into the low power, cellular IoT wireless technology market.

Cellular is a notoriously complex wireless technology that only a handful of engineering teams worldwide truly have the expertise and experience to design at the architectural level. Nordic Semiconductor’s team all originated from outside the company when Nordic hired some of the smartest cellular R&D engineers in the world from a bout of rationalization layoffs in Finland between 2011 and 2014 from companies such as Nokia, Microsoft, Broadcom, and ST-Ericsson.

This means Nordic’s heritage in cellular wireless technology is on-par with any other company in the world: most of Nordic’s cellular IoT design team have been working in cellular design for most of their careers. And most importantly of all, all technical support for the nRF9160 SiP module will come from engineers who designed the product from the ground up.

Powered by sunlight and body heat, the PowerWatch 2 is the first location tracking smartwatch you never need to charge. 

Thalwil, Switzerland – February 12, 2019–u‑blox (SIX:UBXN), a global provider of leading positioning and wireless communication technologies, TransSiP inc, world leader in Power Integrity and MATRIX Industries, leaders in thermoelectric innovation, are announcing the PowerWatch 2, the world’s first GPS smartwatch that you never need to recharge. The smartwatch features the ultra‑small, ultra‑low power u‑blox ZOE‑M8B GNSS receiver to track position, in addition to calories burned, activity level, and sleep, making it an ideal companion for runners, hikers, and swimmers. All this is enabled by TransSiP PI technology which ensures energy harvested is used at maximum efficiency and provides crystal clean power enabling optimum performance.

The PowerWatch 2 is the first GPS smartwatch to offer a 100 percent charge‑free experience. It does away with cables and external batteries by continually topping up its battery using thermoelectric energy generated from body heat as well as solar energy.The watch also excels at the other things smartwatches do, connecting to your smartphone and displaying notifications on your wrist, and tracking activities and visualizing them using dedicated iOS and Android apps, as well as with popular third party health and fitness platforms.

The ZOE‑M8B and TransSiP PI: a winning combination
The PowerWatch 2 delivers location tracking using the low‑power u‑blox ZOE‑M8B GNSS receiver module that consumes as low as 12 mW. Packaged as a (System‑in‑Package), the 4.5 x 4.5 x1.0 mm module helps achieve the watch’s comparatively low 16‑millimeter thickness. And concurrent reception of up to three GNSS constellations means that it delivers high accuracy positioning in challenging situations such as urban or dense forest environments and when swimming.

Satellite based positioning is typically the most power‑hungry process on a sports watch. Providing highly efficient conversion of harvested energy into a very quiet supply of DC power, TransSiP PI enhances the ability of the ZOE‑M8B GNSS receiver module incorporating u‑blox Super‑E technology, to strike an ideal balance between power and performance.Working on a tight power budget, the watch supports 30 minutes of continuous GNSS tracking per day, with unused time accumulating in the watch’s battery pack, e.g., powering two hours of location tracking every four days.

“We put a lot of effort into tailoring the ZOE‑M8B to the needs of small battery powered applications. We couldn’t have wished for a better product to showcase our ZOE‑M8B’s potential for wearables than the PowerWatch 2,” says Florian Bousquet, Principal Product Manager in Standard Precision GNSS at u‑blox.

Douglas Tham, CTO of MATRIX Industries added: “TransSiP PI makes it possible to deliver high performance and high efficiency simultaneously by reducing system noise, eliminating time spent re‑acquiring data, and minimizing the need for additional processing. This means power savings across‑the‑board and enables applications which can be powered solely by energy harvesting.”

“Not only were size, cost and power constrained in developing the PowerWatch 2, we also had to make sure that it met the high performance demands that athletes expect,” says Akram Boukai, CEO and Co‑founder of MATRIX Industries. “The combination of TransSiP PI and the ZOE‑M8B solved all of these pain points for us, enabling the watch to quickly lock in on its position even in weak signal environments.”

Backers of the project on Indiegogo are expected to receive their orders in June, 2019.

DIABNEXT’s ‘CLIPSULIN’ device attaches to insulin pens and employs Nordic’s nRF52832 SoC to wirelessly send recorded insulin injection data via Bluetooth LE or NFC.

Nordic Semiconductor today announces that Taiwan-based DIABNEXT, a healthcare services company, has selected Nordic’s nRF52832 System-on-Chip (SoC) to provide the Bluetooth® Low Energy (Bluetooth LE) wireless connectivity for its ‘CLIPSULIN’ insulin injection monitoring and recording device.

CLIPSULIN attaches to all commonly used disposable and reusable insulin pens and employs a vibration sensor to accurately detect insulin dosage, enabling the user to record their injected insulin units. Using Bluetooth LE or Near Field Communication (NFC) wireless connectivity provided by the Nordic SoC, the data is automatically transmitted to the user’s Bluetooth 4.0 (or later) smartphone, from where the patient can then retrieve important information such as the dosage, date, and time of injection from the ‘DIABNEXT’ app. The iOS- and Android-compatible app functions as a digital logbook for a diabetes patient, not only recording their treatment data, but also enabling the patient to monitor blood sugar levels and physical activity.

As a non-rechargeable device powered by a CR2032 coin cell battery, CLIPSULIN relies on the low power and low sleep-current capabilities of the Nordic SoC to extend the device’s battery life. The nRF52832 SoC has been engineered to minimize power consumption with features such as the 2.4GHz radio’s 5.5mA peak RX/TX currents and a fully-automatic power management system that reduces power consumption by up to 80 percent compared with Nordic’s nRF51 Series SoCs. The result is a Bluetooth LE solution which offers 58 CoreMark/mA, up to twice as power efficient as competing devices.

“Nordic’s Software Development Kit and comprehensive reference designs made the development process significantly easier” – Alice Cheng, DIABNEXT

Nordic’s nRF52832 multiprotocol SoC combines an 64MHz, 32-bit Arm® Cortex® M4F processor with a 2.4GHz multiprotocol radio (supporting Bluetooth 5, ANT™, and proprietary 2.4GHz RF protocol software) featuring -96-dB RX sensitivity, with 512kB Flash memory and 64kB RAM. The SoC also features an NFC-A Tag for use with simplified pairing and payment solutions. The nRF52832 is supplied with Nordic’s S132 SoftDevice, a Bluetooth 5-certifed RF software protocol stack for building advanced Bluetooth LE applications. The S132 SoftDevice features Central, Peripheral, Broadcaster and Observer Bluetooth LE roles, supports up to twenty connections, and enables concurrent role operation.

“We chose the nRF52832 SoC for the CLIPSULIN device primarily for its compact size, low power consumption, stable radio sensitivity, and NFC functionality,” says Alice Cheng, Head of Development & Manufacturing at DIABNEXT. “Furthermore, the SoC’s generous Flash memory allocation enables efficient over-the-air firmware updates.

“Nordic’s Software Development Kit and comprehensive reference designs made the development process significantly easier, while Nordic engineers were always quick to respond to any technical issues we encountered.”

The SoC combines a 64MHz, 32-bit Arm® Cortex® M4F processor with a 2.4GHz multiprotocol radio (supporting concurrent wireless connectivity of Bluetooth 5 and Thread or Zigbee, in addition to ANT™, IEEE 802.15.4, and proprietary 2.4GHz RF protocol software). The SoC has 1MB Flash memory and 256kB RAM. An on-chip PA features -95dBm RX sensitivity (at 1Mbps Bluetooth LE), a maximum output power of 8dBm, and a total link budget of 103dBm. The chip supports all the features of Bluetooth 5 (including 4x the range or 2x the raw data bandwidth (2Mbps)) compared with Bluetooth 4.2.

The SoC is supplied with Nordic’s S140 SoftDevice, a Bluetooth 5-certified software protocol stack for building long range and high data Bluetooth LE applications. The S140 SoftDevice offers concurrent Central, Peripheral, Broadcaster, and Observer Bluetooth LE roles, and supports high throughput and long range modes as well as advertising extensions. OpenThread and Zigbee stacks are available through Nordic’s nRF5 SDK for Thread and Zigbee.

“The nRF52840’s launch followed an extensive design and development process by the company’s engineering team and builds on Nordic’s many years of Bluetooth LE and low power wireless hardware and software expertise,” says Geir Langeland, Nordic’s Director of Sales & Marketing. “We are proud that those efforts have been appreciated by the nRF52840’s recognition as a winning solution in the highly competitive RF sector from the editors of a leading U.S. electronic design title.

MIL-DTL-17, formerly known as MIL-C-17, is the US military specification (MIL-SPEC) that defines the standards and procedures for qualifying and verifying flexible and semi-rigid coaxial cable for Hi-Rel applications. Because of the rigorous requirements of MIL-DTL-17, many applications that require high reliability (Hi-Rel) coaxial cable may opt for, or require, MIL-DTL-17 coax. There are many requirements and aspects of MIl-DTL-17 coaxial cable, including the following:

• Qualification
• Materials
• Design and construction
• Visual and mechanical
• Operational
• Marking
• Weight
• Workmanship

Hence, a coaxial cable won’t fulfill the MIL-DTL-17 specification unless it meets each category of criteria. Depending on the application, some “Hi-Rel” coaxial cables may call out only specific requirements of the MIL-DTL-17 specification. There are four key areas of inspections detailed in the specification, material, qualification, conformance, and final inspection. Failure at any of these inspections often requires discarding failed parts and/or re-inspection.

As part of these inspections, there are several electrical and mechanical tests that must be performed. Some of these tests are only performed on qualifying batches of coaxial cable, while some tests are performed on each batch of coax to ensure conformance. These tests include:

• Dimensional measurements
• Dielectric withstand voltage
• Shield construction
• Attenuation
• VSWR
• Characteristic impedance
• Conductor adhesion
• Capacitance
• Inductance

Moreover, there are destructive tests performed on sample parts during conformance testing. These tests include:

• Capacitance stability
• Aging stability
• Stress crack resistance
• Outer conductor integrity
• Dimensional stability
• Contamination
• Bendability
• Flammability
• Heat distortion
• Tensile strength and elongation
• Physicals (aged)

Lastly, each coaxial cable is subject to a final inspection, which differs in requirements between semi-rigid cable and flexible cable:

• Semirigid Cable
> Continuity
> Voltage withstanding

• All other Cables
> Continuity
> Spark test
> Voltage withstanding
> Insulation resistance
> Out-of-roundness of jacket measurements

The exact parameters and methods of these tests are detailed in MIL-DTL-17, and/or are further detailed in referenced military and industrial specifications. These tests must also be performed in a qualified facility and the cables tested for qualification and conformance must be produced in the same was as production cables.

Many of the specifications within MIL-DTL-17 are referred to as “RG”, though RG coaxial cables have become a generalized industry term, and not a standardized set of cable specifications. For example, MIL-DTL-17 thoroughly describes maximum attenuation over a range of frequencies, along with precise physical properties, such as conductor plating thickness, and there are no such specifications defining RG coaxial cables. Moreover, a MIL-DTL-17 coaxial cable supplier should have their product on the Qualified Products List (QPL), which isn’t case for readily available RG coax.
