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, great effect under sunlight, it is an ideal choice for applications such as shelf label, industrial instrument, and so on.
