Hackster.io is running an Advanced Wearables design challenge in partnership with Nordic Semiconductor. Participation is free and Nordic is giving away 50+50 bundles of hardware to eligible idea submissions. There are two challenges and two bundles of hardware. Bundle A includes Nordic’s latest nRF5340 DK BLE5 development board, Adafruit 2.2″ TFT Display and nRF52840 Dongle. The Challenge A – Dream Smart Wearables – is to build and document smart wearable devices of any kind using the bundled hardware. You can participate even if you did not win the giveaway. You can purchase the hardware yourself and complete the project.

Challenge B – Remote Patient Monitoring – is to build smart wearable devices for remote patient monitoring. For example, devices that measure body temperature, heart rate etc. Bundle B includes nRF5340 DK, Power Profiler Kit II + nRF52840 Dongle. The dongle is a complementary part and does not need to be used in the project. It is useful for debugging BLE communication.

Submitting a short demonstration video can gain you bonus point and may increase your chance of winning. The Grand Prize is a $2,000 value VISA gift card, and winners of other two categories get $500 each. Additionally, 15 runner-up projects will receive T-shirt, swag and surprise hardware from Hackster.
