Overview1. This is an E-Ink display module, 4.2inch, 400x300 resolution, with embedded controller, communicating via SPI interface.2. 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.Features1. No backlight, keeps displaying last content for a long time even when power down2. Ultra low power consumption, basically power is only required for refreshing3. SPI interface, for connecting with controller boards like Raspberry Pi/Arduino/Nucleo, etc.4. Onboard voltage translator, compatible with 3.3V/5V MCUs5. Comes with development resources and manual (examples for Raspberry Pi/Arduino/STM32)Specifications1. Operating voltage: 3.3V~5V2. Interface: 3-wire SPI, 4-wire SPI3.
