This is an E-Ink display HAT for Raspberry Pi, 2.7inch, 264x176 resolution, with 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 applications such as shelf label, industrial instrument, and so on. Features No backlight, keeps displaying last content for a long time even when power down Ultra low power consumption, basically power is only required for refreshing Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards, Jetson Nano Onboard 4x Keys,SPI interface, for connecting with other controller boards like Raspberry/Arduino/Nucleo, etc. Onboard voltage translator, compatible with 3.3V/5V MCUs Comes with development resources and manual (examples for Raspberry Pi/Jetson Nano/Arduino/STM32). Specifications Operating voltage: 3.3V/5V Interface: 3-wire SPI, 4-wire SPI Outline dimension: 85mm x 56mm Display size: 57.288mm x 38.192mm Dot pitch: 0.217 x 0.217 Resolution: 264 x 176 Display color: black, white Grey level: 2 Full refresh time: 6s Refresh power: 24mW(typ.)
