In this video I'd like to setup and test new MH-ET LIVE 1.54" ePaper display. This display has 200 x 200 pixels resolution and it is available in 3 different color combinations: black-white, black-yellow-white, black-red-white. It works with 3.3 V or 5 V and uses SPI for communication with microcontroller (in my case ESP8266). Advantage of this display is zero power consumption after refresh but you have to consider long refresh time. This display is perfect for battery-powered/solar-powered applications or other low-power projects. Source is minified for ESP8266, check the library for Arduino/ESP32 versions.
