E-Ink (Electronic Ink) display has several benefits compared to other display technologies:

• High Visibility and Contrast
• Wide viewing angle
• and super low power consumption. It can retain the display for very long time after power is removed.

This is an E-Ink display HAT for Raspberry Pi, 2.13inch, 212x104 resolution, with 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, 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
• Compatible with Raspberry Pi Zero/Zero W/Zero WH/3B/3B+
• Preserved solder pads for SPI interface, for connecting with other controller boards like Arduino, etc
• Onboard voltage translator, compatible with 3.3V/5V MCUs
• Comes with development resources and manual (examples for Raspberry Pi/Arduino/STM32)
• Stack perfectly on Raspberry Pi Zero board and of course a little smaller than Raspberry Pi 3B/3B+.
