This is an E-Ink display HAT for the Raspberry Pi. The display is 2.7" with a 264x176 resolution, and includes an embedded controller communicating via SPI interface. Due to the advantages like ultra-low power consumption, wide viewing angle, clear display without electricity, it is an ideal choice for low-power applications and projects. It's one of the recommended displays for the Pwnagotchi project!
