DESCRIPTION

400x300, 4.2inch E-Ink Display Module, Three-Color, SPI Interface

Overview

This is an E-Ink display module, 4.2inch, 400x300 resolution, with 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.

Features

No backlight, keeps displaying last content for a long time even when power down

Ultra low power consumption, basically power is only required for refreshing

SPI interface, for connecting with controller boards like Raspberry Pi/Nucleo, etc.

Onboard voltage translator, compatible with 3.3V/5V MCUs

Comes with development resources and manual (examples for Raspberry Pi/Jetson Nano/STM32, etc.)
