Tibbo Technology Announcing LTTP3

Pinguinistas of the world, rejoice! Our Tibbo Project System (TPS) family now includes a Linux-based Tibbo Project PCB (LTPP).

Based on the powerful 1GHz Cortex-A8 Sitara CPU from Texas Instruments and carrying 512GB of RAM and 512GB of flash memory, the new LTPP3 board runs our own, highly polished distribution of Linux that is derived from the RedHat line and updated with the latest and greatest kernel and drivers.

The LTPP3 is mechanically and electrically compatible with our Tibbit blocks and size 3 Tibbo Project Box (TPB3) enclosures. This sets the LTPP3 apart from plain vanilla products such as Raspberry Pi and BeagleBone. While offering affordable Linux-based computing in a compact package, these devices do very little toward providing an attractive housing or a quick way to add desired I/O resources. In contrast, Tibbo Project System delivers aesthetically pleasing TPB enclosures to house the board, and a plethora of Tibbit modules and connectors to expand the board’s IO capabilities.

There are four distinctive ways in which you can use the new LTPP3.

Use it with Embedded AggreGate

Immediately upon the release of the LTPP3, you will be able to order your Linux TPS system with Embedded AggreGate software. Serving as the board’s execution environment, AggreGate lends LTPP3 its immense power of data collection, processing, and visualization. Further, AggreGate provides a uniform, consistent access to external data, devices, and systems using more than 100 supported communications protocols. Via a specially designed middleware C library, Embedded AggreGate is also able to access the board’s hardware resources, such as GPIO lines, serial ports, as well as Tibbit modules installed in board’s sockets.

Run Node.js applications

LTPP3 comes with Node.js preinstalled. We are currently developing Node.js modules for accessing the board’s hardware resources and installed Tibbit blocks. You can also utilize many existing Node.js modules, such as serialport and socket.io.

Execute TiOS applications

We are currently porting our popular Tibbo OS (TiOS) to Linux. When this work is completed, you will be able to run TiOS as a Linux application and execute existing Tibbo BASIC and Tibbo C code with little or no modifications. Needless to say, the new LTPP3 board will crunch Tibbo BASIC and Tibbo C apps at unparalleled speeds.

Use the LTPP3 as a generic Linux board…

… that comes in an attractive housing and may be extended with Tibbit blocks. Linux can be utilized in myriad different ways. Choose yours and deliver your project on the LTPP3 board and TPS product family.

The LTPP3 board is available for preorder. Deliveries start in May 2016. Click here to order yours.

Nordic Semiconductor-powered Bluetooth Smart modules ease development of wireless solutions in professional industrial, healthcare, and other applications

Professional grade u-blox NINA-B1 Series modules employ Nordic Semiconductor’s nRF52832 SoC for a complete, compact Bluetooth Smart wireless solution requiring no additional hardware

Nordic Semiconductor today announces that Thalwil, Switzerland-based u-blox (SIX:UBXN) has selected Nordic’s nRF52832 Bluetooth® Smart System-on-Chip (SoC) for its NINA-B1 Series stand-alone modules.

The compact NINA-B1 ultra low power Bluetooth Smart modules are designed for space-constrained applications employing coin cell batteries. The modules reduce development time by providing a complete wireless solution and are tailored for OEMs who wish to develop their own application software, and/or add Bluetooth services to the Bluetooth Smart stack using the ARM® mbed Integrated Development Environment (IDE). Alternatively, the NINA-B1 can be ordered with incorporated firmware enabling the u-blox Serial Port Service to replace serial cables or access UART devices using Bluetooth Smart. The modules also allow developers to seamlessly connect their wireless devices to both iOS and Android Bluetooth Smart Ready units such as tablets and smartphones.

The professional grade modules are offered in either a 10 x10.6 x 1.4 mm (NINA-B111), or 10 x 14 x 3 mm (NINA-B112) form factor, making them suitable for a wide range of space-constrained applications in segments such as healthcare, asset tracking, connected cities, home automation, smart energy, manufacturing, and telematics. The NINA-B1 module features variants with PCB-mounted antenna or for use with an external antenna, allowing smaller designs.

The modules provide a generous set of general-purpose input/outputs (GPIOs), as well as SPI, I2C, UART, and I2S interfaces together with analog inputs. Additional sensors, for example accelerometers and temperature sensors, can be connected directly to the module.

The NINA-B1 has a maximum output power of 7dBm and enables different power saving modes and configurations. Different sections of the module can be powered off when not needed, and complex wake-up events can be generated from different external and internal inputs.

The nRF52 Series is Nordic Semiconductor’s sixth generation of ultra low power (ULP) wireless connectivity solutions. The nRF52832 features a 64 MHz, 32-bit ARM Cortex™-M4F CPU which delivers up to 60 percent more generic processing power, offering 10 times the Floating Point performance and twice the Digital Signal Processing (DSP) performance compared to competing solutions. The 2.4 GHz multiprotocol radio offers Bluetooth Smart (fully compatible with Bluetooth Version 4.2 (v4.2)) support with -96 dB RX sensitivity and 5.5 mA peak RX/TX currents. The nRF52832 also features 512 kB Flash memory and 64 kB RAM, a fully-automatic power management system that reduces power consumption by up to 80 percent compared with the nRF51 Series, on-chip analog and digital peripherals for glueless interfacing to external components, and an NFC™ tag for consumer-friendly Touch-to-Pair.

“In addition to allowing our customers to design their own application code and run it on the modules, we have developed our own advanced serial port service firmware for the modules and plan to add support for future applications including IPv6,” says Pelle Svensson, u-blox Product Marketing Manager, Short Range.

“Low power, the powerful microprocessor, large Flash size, and Bluetooth v4.2 compliance were the main drivers behind the decision to select Nordic’s nRF52832 SoC for the NINA-B1 modules.”

Qorvo Duplexer Versus Multiplexer

Simplifying and Accelerating the Deployment of Carrier Aggregation

Multiplexer solutions help simplify and accelerate adoption of carrier aggregation (CA) in 4G LTE devices. These compact multiplexer devices deliver up to 60% space savings and cover primary band combinations such as Bands 1 and 3 used in CA deployments.

But First… What Are Multiplexers?

A multiplexer is a device that separates signals from a common input to multiple outputs, sorting the output ports according to specific band frequencies. As shown in Figure 1 below, a multiplexer takes the place of two duplexers, reducing size and complexity for the system engineer. However, this introduces challenges for the multiplexer designer. The multiplexer designer must painstakingly match individual band duplexer filters, meeting stringent specifications for isolation, cross isolation, attenuation and insertion loss.

How Do Duplexer and Multiplexer System Architectures Differ?

Multiplexers used in RF front-end architectures enable CA, which helps increase data speeds for mobile device networks. They also simplify the design for engineers. Some architectures using multiplexers require no switch (right side of Figure 2) rather than a duplexer design using two single-throw switches (left side of Figure 2).

IMAGE

Figure 2. System Approach: 2 Duplexers to 1 Multiplexer

The switch-multiplexer combination also gives the following benefits over the switch-duplexer approach:

Switch-Multiplexer Approach

  • Designed with complementary matching so
    filters can coexist in one package
  • Less board area required
  • Lower insertion loss/better link budget
Switch-Plexer Approach

  • Phase shifters needed, programmability/tradeoffs
  • Takes up more board area
  • Increased link budget compared to switch multiplexer approach

In short, multiplexer solutions simplify design, reduce product footprint, conserve power and improve overall system performance. This gives mobile device design engineers the ability to offer customers a unique product in addition to accelerating their delivery of next-generation products.

Qorvo® Multiplexers

Qorvo multiplexers meet global regional device requirements integrating multiple SAW and BAW filters. They additionally cover the primary band combinations used in CA deployments, such as Bands 1+3 and Bands 39+41.

  • QM25005: Qorvo’s QM25005 multiplexer features LowDrift™ transmit and receive filters for FDD-LTE Bands 1 and 3 in a highly compact 3.0 x 2.0 mm form factor. Enabling downlink CA, the QM25005 is qualified with leading LTE chipsets and performance-optimized to deliver best-in-class insertion loss and high isolation, resulting in improved receive sensitivity and coverage.
  • QM25001, QM25011, QM25012: These three Qorvo multiplexers feature LowDrift™ BAW filter technology for TDD-LTE Bands 39 and 41, each developed in partnership with leading chipset suppliers. With a compact 2.5 x 2.0 mm footprint, the QM25001 is designed for global smartphones supporting the full Band 41 spectrum for worldwide use. The QM25011 and QM25012 are designed for China domestic smartphones and optimized for China’s Band 41 narrowband allocation. The QM25011 includes primary transmit and receive filters in a 1.7 x 1.3 mm package, while the complementary QM25012 provides diversity receive filters in an even smaller 1.5 x 1.1 mm footprint. Both products provide at least a 60% space savings over discrete components.
