EPDiy is a driver board and accompanying software library for driving affordable E-Paper (E-Ink) display modules, typically salvaged from e-readers, using ESP32/ESP32-S3 microcontrollers. It provides 4bpp 16-grayscale rendering support with WiFi/Bluetooth connectivity, LiPo battery charging, and drivers for both ESP-IDF and Arduino.
Use cases
- drive a cheap e-ink display from an old e-reader with an ESP32
- build an e-paper weather station
- make an e-paper picture frame
- create a serial terminal display for a Raspberry Pi
- build a battery-powered e-ink dashboard
- display images from Immich on an e-paper screen
- build a low-power e-ink music player dashboard
When to choose
- you want to drive bare e-paper display matrices with 16-level grayscale at good speeds
- you need WiFi/Bluetooth alongside an e-ink display
- you want ultra-low deep sleep power draw on battery
- you prefer ESP-IDF or Arduino tooling for embedded display projects
When to avoid
- you need a ready-made consumer e-ink module with connector and support out of the box
- your display is not one of the supported matrix-based e-paper panels or lacks a compatible connector/adapter
- you need fast full-color e-paper updates
- you require Arduino IDE performance on V7 boards, where update speeds are significantly lower
