This is a epaper module consist of 2.7 inch capacitive touch screen e-ink display module with its development board, 264x176 resolution, SPI interface, and the display is capable to display images with black and white content. It supports 3s full refresh, 1.5s fast refresh and 0.42s partial refresh. Your image holds indefinitely without power – put up your image, then shut down the power. Once these e-paper modules are updated they don't require any power and can actually be disconnected entirely and the content will remain on the display indefinitely. This e-paper display GDEW027T91-T01 is perfect for low power devices powered by solar or batteries.
ESP32-L(T01) evaluation kit is used to help users develop e-paper display projects with provided source code to create more differentiated solutions. It is designed for SPI e-paper display. It can realize the collaboration of touch screen and e-paper display to facilitate the early debugging of customers. And it is added the functions of LED indicator light, Reset button, font chip, Flash chip and etc.
