This is an E-Ink display HAT for Raspberry Pi, 2.7inch, 264x176 resolution, with an embedded controller, communicating via SPI interface, supports red, black, and white three-color display.
Due to the advantages like ultra-low power consumption, wide viewing angle, the great effect under sunlight, it is an ideal choice for applications such as shelf labels, industrial instruments, 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
- Compatible with Raspberry Pi 2B/3B/Zero/Zero W
- Onboard 4x Keys
- SPI interface, for connecting with other controller boards like Raspberry/Arduino/Nucleo, etc.
- Comes with development resources and manual (examples for Raspberry Pi/Arduino/STM32)
