This is an E-Ink display HAT for Raspberry Pi, 2.13inch, 212×104 resolution, with an embedded controller, communicating via SPI interface, supports the red, black, and white three-colour display.
There is no backlight so it can keep displaying last content for a long time even when the power is down. As these displays have no backlight panels and it doesn’t need a continuous power supply to display the (static data with periodic intervals) data on the screen, it has a great advantage of ultra-low power consumption. Also, it has a wide viewing angle, great viewing effect under sunlight, Basically power to the display is only required for refreshing. For connecting with controller boards like Raspberry Pi/Arduino/Nucleo, etc.. SPI interface can be used.
Features:
-No backlight keeps displaying last content for a long time even when power is down
-Ultra low power consumption, basically power is only required for refreshing
-Compatible with Raspberry Pi Zero/Zero W/Zero WH/2B/3B/3B
-Preserved solder pads for 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/Arduino/STM32)
