This is an E-Ink display HAT for Raspberry Pi, 2.13inch, 250×122 resolution, with embedded controller, communicating via SPI interface, supports partial refresh.
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
SPI interface, for connecting with other controller boards like 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)
