296x128 2.9inch Black / White E-Ink Display

This is a 2.9inch E-Ink/E-Paper display module with 296x128 pixel resolution, with an integrated controller that communicates via the SPI interface. This black/white display supports partial area updates, allowing individual areas to be updated quickly within 0.3 seconds. A full display update only takes 2 seconds. Because of 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. A connection cable is included in the delivery, with which you can easily connect the display to a Raspberry Pi. For an Arduino Uno or if you want to plug it into a breadboard, you need 8 x Male/Male Dupont cables. 

Features: 

• Onboard level converter making it compatible with 3.3V and 5V microcontrollers
  
• Displays remain on the display even without power supply
  
• Ultra low power consumption
  
• Basically, power is only needed for refreshing
  
• SPI interface for connection to controller boards like Raspberry Pi, Arduino, ESP8266 or ESP32
  
• Good documentation and example code available at Waveshare Wiki
  
• Program examples available for the following controllers: Arduino, stm32, and Raspberry Pi
