SensWear is an open-source hardware development platform for wearables based on Nordic nRF54L15 Bluetooth LE SoC and a range of sensors designed for researchers, developers, and companies building smart rings, wristbands, patches, and other custom devices. The solution is mainly comprised of flexible boards, including the SensWear core board with an nRF54L15 MCU and a 6-axis IMU sensor, and daughter boards with either PPG and optical sensing, temperature sensing, capacitive touch sensing, or haptic feedback. Since the solution is modular, developers can also design their own compatible sensor boards without redesigning the main wearable system. However, we can still take a quick look at software support with a video demo using previous-generation rigid PCBs. The core board can be purchased separately for 699.99 Euros, and daughter boards for 99.99 Euros.
