4.2 inch E-Ink Raw Display Panel - Tri-color (Red)

This is an E-Ink raw display, 4.2inch, 400x300 resolution, with an embedded controller, communicating via SPI interface, supports red, black, and white three-color display.

Due to the advantages like ultra-low power consumption, wide viewing angle, clear display without electricity, it is an ideal choice for applications such as shelf label, industrial instrument, and so on.

After integrates with Universal ESP8266 E-Paper Driver Controller, you can display graphics and text from ESP8266:

After integrates with WiFi and Bluetooth e-Paper Driver Board - ESP32 Wireless, you can display graphics and text from ESP32:
