An open-source sleep tracker based on the Seeed Studio XIAO nRF52840 Sense microcontroller.
- Seeed Studio XIAO nRF52840 Sense
- 1 Spool Inland TPU, Black
- A&S Power 652030 3.7V 350mAh LiPo Battery
- S2B-PH-SM4-TB Battery Connector
Requires soldering the battery connector to the Seeed Studio board, and I also recommend hot glue to give it some strain relief. There is room for it in the 3D model.
Superglue the 2 halves of the case together once everything is working.
You will need to flash CircuitPython onto the board before you're able to load the microcontroller program.
The mobile app is based on the flutter_blue_plus example program.
