ESP32 e-Paper Display
A 7" 3-color e-paper display with an ESP32 driver board and Raspberry Pi backend.
A 7" 3 color (B/W/R) e-Paper Display with an ESP32 driver board, in a custom frame. A Raspberry Pi handles data fetching and image generation according to templates.
I'm still working out the best way to handle the separation of duties between the ESP32 and the RPi. Currently the Pi downloads data and produces display images, though library stability has been problematic.
What's Next
Future improvements include developing a more configurable backend script that outputs HTML, potentially for Home Assistant integration. The plan is to implement battery power for the ESP32 with occasional wake cycles to fetch composed images, possibly triggered by a proximity sensor.
