This E-Paper Raw panel has a 400 x 300 resolution, a viewing angle of over 170° and red, black, yellow and white colours. Without the need for a backlight, it saves on energy by continuing to keep the latest content you had put on there even when powered down. This means it will consume barely any power, and it will only be needed when it's refreshing. Online development resources and a manual are included, with examples for Raspberry Pi, Jetson Nano, Arduino, and STM32. Note: an e-Paper Raw Panel Driver HAT will be needed to run this display.
