Garmin’s first child activity monitor uses a Nordic Semiconductor nRF52832 SoC and will be showcased on Nordic’s booth at CES in January

Designed for kids to wear around the clock, the Garmin vívofit jr. is a highly accurate and sophisticated swim-friendly device that lets parents track steps, sleep, and assign chores and rewards, while running for over a year from a regular (CR1632) coin cell battery that eliminates the hassle of re-charging for busy parents

Nordic Semiconductor today announces that Garmin has specified a Nordic nRF52832 Bluetooth® low energy SoC at the heart of Garmin’s first child activity monitor: the swim-friendly vívofit® jr. that is designed to motivate kids to achieve various parent-assigned activities and chores with reward coins and games.

The Garmin vívofit jr. will be showcased on Nordic Semiconductor’s booth at International CES 2017 in January, and is said to offer all the accuracy and sophistication of Garmin’s adult vívofit activity trackers (including the same 64×64-pixel display featured on the Garmin vívofit 3) but with a stripped-down feature-set relevant to children. This enables the vívofit jr. to deliver a one-year-plus battery life from a user-replaceable CR1632 coin cell (watch) battery to eliminate the hassle of recharging for parents.

Each Garmin vívofit jr. is controlled from a free companion app designed to be installed on a parent’s smartphone, that can also monitor multiple children each wearing a vívofit jr. monitor simultaneously.

The single-chip nRF52832’s high performance 64MHz, 32-bit ARM® Cortex® M4F processor and full range of programmable on-chip analog and digital peripherals are used to monitor steps, movement (in the form of a move bar displayed on the vívofit jr. after a period of inactivity), and sleep – but in a highly-efficient and optimized way that minimizes demand on the battery. The nRF52832 also enables collected activity data to automatically sync to a parent’s smartphone via Bluetooth low energy wireless technology.

“Garmin has been using various Nordic Semiconductor Bluetooth low energy and ANT wireless technology chips in a wide range of its sports products for many years,” comments Justin Lyons, Design Engineering Manager, Fitness Segment, at Garmin. “We find by employing Nordic’s ultra-low power wireless technology we are able to develop and engineer sports products that give our customers the high-quality experience and reliability they have come to expect and rely on from Garmin.”

“The Garmin vívofit jr. demonstrates the level of sophistication driving the wearables market forward,” comments Geir Langeland, Nordic Semiconductor’s Director of Sales & Marketing, “in that even activity monitors designed for kids now offer comparable leading-edge performance and feature sets as their adult-targeted equivalents.”
