OV-Watch is an open-source smart watch project built on an STM32F411 microcontroller running FreeRTOS with an LVGL-based user interface. It includes full firmware, bootloader with Bluetooth OTA updates, and open-source hardware designs for DIY assembly.
Use cases
- build your own open-source smart watch
- learn embedded development with STM32 and FreeRTOS
- study LVGL GUI programming on a real wearable device
- flash custom firmware onto a DIY smartwatch
- implement low-power sleep modes on STM32
- add Bluetooth OTA firmware updates to an embedded project
When to choose
- you want a fully open-source smartwatch with open hardware designs
- you are learning STM32, FreeRTOS, or LVGL through a complete real-world project
- you want a hackable wearable platform with OTA updates
When to avoid
- you need a production-ready consumer smartwatch with app ecosystem support
- you cannot solder SMD components and only want ready-made hardware
- you need iOS/Android companion app features out of the box
