waveshare 7.5inch E-Ink Raw Display Compatible with Raspberry Pi 5/4B/3B/Zero/Zero W/Zero 2W/Pico/Pico W/Pico WH 800×480 Resolution with SPI Interface Without PCB

This display is exactly what it is advertised to be...a 7.5" e-paper display. Note that this display DOES NOT come with a driver board, so you will need to purchase one separately for your setup.I connected mine to a Waveshare ESP32 board, so I used Arduino IDE to program it. There is a steep learning curve with these displays if you've never worked with e-paper...it's not as simple as just sending a "print" command to the display; you have to build up a display buffer and then send the buffer contents to the display and then refresh the display.If you're looking for a large, low power, easily readable display for your project, this is a great option.

Waveshare does not bother to maintain their documentation. Very outdated instructions on wiki
