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
