ESP32 Universal Raw e-Paper Driver Board WiFi Bluetooth

This universal Waveshare e-paper driver board with ESP32 connects raw e-ink displays (bare e-paper panels without a board) directly. With the Waveshare example code, images can be uploaded via a web page over WiFi, converted and shown on the e-paper display, and with the example app for Android also via Bluetooth. Your own Arduino programs can be loaded as well.
