Watchy is a fully open-source E-Ink smartwatch built on ESP32, accompanied by an Arduino library for developing custom watch faces and firmware. It combines open hardware design with a C/C++ software library for the Arduino ecosystem.
Use cases
- build a custom e-ink smartwatch
- develop custom watch faces for Watchy
- program an ESP32 wearable with Arduino
- create a low-power e-paper display project
- experiment with BLE-connected wearable firmware
- learn embedded development on open-source hardware
When to choose
- you want a hackable, fully open-source smartwatch platform
- you prefer Arduino-based ESP32 development for wearables
- you need an ultra-low-power e-paper display device
- you want to customize watch faces and watch firmware yourself
When to avoid
- you need a polished consumer smartwatch with app ecosystem out of the box
- you require color displays or high-refresh-rate screens
- you want a turnkey wearable without writing or flashing firmware
