Overview

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.

There are currently two versions, a GPS edition (pre-released, work in progress) and a Light edition (released), which share the following hardware:

  • EPS32-micro-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
  • microSD

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).
