250x122 2.13inch Black / White E-Ink Display Raspberry Pi HAT

This is a 2.13 inch E-Ink / ePaper display module with 250 x 122 pixel resolution, with an integrated controller that communicates via the SPI interface. This affordable display is perfect for the Raspberry Pi Zero W as it has the same dimensions. However, it can also be used for the Raspberry Pi 2B or 3B. Due to its extremely low power consumption, it is great for battery-powered applications. These displays are also used in retail as price tags, where they can be operated with a battery for several years. The display has a very good viewing angle and can also be read very well in sunlight. This black and white display supports updates of sub-areas so individual areas can be updated quickly within 0.3 seconds. An update of the entire display also only takes 2 seconds.

Features:

Onboard voltage converter, compatible with 3.3V/5V MCUs
Supports Partial Refresh (updating of subareas) in just 0.3 seconds
Display content is retained even without power supply
Ultra low power consumption
In essence, power is only needed for refreshing
SPI interface for connecting to controller boards such as Raspberry Pi, Arduino, ESP8266 or ESP32
Compatible with Raspberry Pi 2B/3B/Zero/Zero W
Good documentation and example code available on Waveshare Wiki
Programming examples for the following controllers are available: Arduino, stm32, and Raspberry Pi
