Universal E-Paper Driver Board

This board drives Waveshare SPI-interface raw e-paper panels using an onboard ESP32 module. It targets makers who want wireless image updates from a PC or smartphone without designing custom driver circuitry.

Arduino-compatible wireless setup

The ESP32 enables Arduino IDE development and ships with an Android app for Bluetooth EDR refresh plus HTML host code for webpage-driven updates. Users must match the panel pinout to the board header; mismatched wiring is the most common cause of blank or corrupted displays.

Sustained wireless operation

Under continuous use the ESP32 maintains Wi-Fi or Bluetooth links while running Floyd-Steinberg dithering on BMP, JPEG, GIF or PNG files. Extended refresh cycles increase power draw, so a stable 5 V supply is needed to avoid brown-out resets during long sessions.

Questions about this item

How can I confirm the board is correctly driving my e-Paper panel after setup?

Load an image through the Android app over Bluetooth or the HTML host page over Wi-Fi; the panel should refresh and show the picture with Floyd-Steinberg dithering applied.

What comes in the box and what must I source separately?

The driver board with onboard ESP32 is supplied; you must provide a compatible Waveshare SPI-interface raw e-Paper panel and a USB power source.

Which version or capacity of this board should I choose?

Only one universal variant exists; select the matching raw panel size and resolution you need, as the board supports multiple SPI panels.
