It consists of a flexible core board with an Arm Cortex-M33 MCU and 6-axis IMU, plus interchangeable daughter boards for PPG/SpO₂, temperature, capacitive touch, and haptic feedback. The full stack is open-source under MIT license on GitHub, including hardware design files, Zephyr-based firmware, Android/iOS apps, and Python/TypeScript SDKs for sensor data streaming and ML applications. A complete developer bundle is available for ~€850, targeting researchers and companies building smart rings, wristbands, and patches. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What sensors and MCU does the SensWear wearable development platform use? SensWear's core board uses the Nordic nRF54L15 Bluetooth LE SoC, featuring an Arm Cortex-M33 CPU running up to 128 MHz plus a RISC-V coprocessor, 256 KB SRAM, and 1.5MB non-volatile memory, alongside a Bosch BHI360 six-axis IMU and sensor hub. Interchangeable daughter boards add PPG/optical sensing (MAX30101), temperature sensing (MAX30208), capacitive touch (MTCH6102), and haptic feedback (DRV2605). _Developers prototyping wearables can follow daily.dev for hardware platform breakdowns like nRF54L15-based designs._ ### How much does the SensWear developer kit cost? The complete SensWear developer bundle costs 849.99 Euros (about $970), including the core board, four daughter boards, and a debug board. The core board alone sells for 699.99 Euros, while individual daughter boards cost 99.99 Euros each. The relatively high price reflects its status as a niche developer platform for wearable prototyping. _Anyone budgeting a wearable prototype can track niche hardware platform pricing like this via daily.dev._ ### What software and SDK support does SensWear provide for building custom wearable applications? SensWear ships Zephyr-based firmware along with Android and iOS mobile apps, plus developer SDKs in Python and TypeScript for streaming raw sensor data and building custom signal-processing or machine-learning applications. Hardware design files and firmware are released under an MIT license on GitHub, and the modular daughter board interface lets developers design their own compatible sensor boards without redesigning the main system. _Engineers building sensor-driven ML pipelines can find open hardware and SDK breakdowns on daily.dev._ ## Community discussion Top comments from developers on daily.dev. **@senswear** · 0 upvotes > We are launching a crowd supply campaign.
