The 4.2inch e-Paper Module (B) is an E-Ink display module that offers a 400x300 resolution. It comes with an embedded controller and utilizes the SPI interface for communication. This module is capable of displaying content in red, black, and white, allowing for versatile visual representation. Its key advantages include ultra low power consumption, a wide viewing angle, and the ability to provide clear display even without electricity. The module is specifically designed for applications such as shelf labels and industrial instruments.
Note: Please note that the raw panel of this e-Paper module requires a driver board. If you are using this e-Paper module for the first time, we highly recommend purchasing the HAT version or acquiring an additional driver hat for easy use. Alternatively, you have the option of creating the driver board yourself. The instructions provided in this document are based on the version with a PCB or driver board.
