WaveShare ESP32 Universal Raw e-Paper Driver Board WiFi Bluetooth

Practical universal e-Paper Driver Board with an ESP32 microcontroller for directly connecting Raw E-Ink displays. With this ESP32 Driver Board, you can directly connect our affordable Raw e-Paper displays (e-Paper raw panels without a circuit board) to the ESP32. Waveshare already provides example code that you can load onto the ESP32, allowing you to upload and convert images directly via a website. Images can thus be easily displayed on the e-Paper display via WiFi or Bluetooth.

Features of the Universal Raw e-Paper Driver Board ESP32:
An example app for Android is available, enabling you to transfer images to the display via Bluetooth using your smartphone. This is a universal driver board for e-Paper raw panels. Thanks to the ESP32, a WiFi connection to the network is possible, allowing you to conveniently transfer and display images from your PC or smartphone over WiFi. You can also load your own Arduino programs onto the ESP32. ESP32 Arduino compatible. Supports the Floyd-Steinberg dithering algorithm, allowing for more color combinations and better shadow representation for images. Supports common image formats: BMP, JPEG, GIF, PNG, etc. A detailed user manual in English is included.
