The open-source operating system/firmware for the Open-Smartwatch, an ESP32-based DIY smartwatch built from open hardware modules and 3D-printable cases. It is built with PlatformIO, supports watchfaces, apps, games, and optional Lua scripting, and includes an emulator for development.
Use cases
- flash custom firmware onto an open-source smartwatch
- build my own DIY ESP32 smartwatch
- develop custom watchfaces and apps for a wearable
- run an emulator to test smartwatch firmware without hardware
- add Lua scripting to a smartwatch project
When to choose
- you own or are building an Open-Smartwatch (Light or GPS edition)
- you want a fully open, modifiable smartwatch firmware
- you want to experiment with wearable development on ESP32 hardware
When to avoid
- you need firmware for a commercial smartwatch like Pebble, Wear OS, or Apple Watch
- you want a polished consumer smartwatch experience out of the box
- your project targets non-ESP32 microcontrollers
