The Open-SmartWatch is an open source project created by @pauls_3d_things/p3dt.net. It consists of hardware modules, 3D printable cases and a custom operating system to build smartwatches with the goal that they can be assembled, repaired, and modified by everyone.
- ESP32-pico-D4: 2x240MHz, 320KB RAM
- Bluetooth 4.2 BR/EDR BLE
- WiFi 2.4GHz 802.11 b/g/n
- GC9A01 240x240 16bit TFT display (round)
- BMA400 Accelerometer + Pedometer
- MCP73831 LiPo Charger
- CH340E USB Serial
The GPS edition has additionally:
- Quectel L96 GPS module
- 4MB RAM
The PCB (KiCAD), Case design files (Blender), and Operating System (C++/Arduino/PlatformIO) are all created with open source software, and are hosted on GitHub (see links below).
