296x128 2.9inch 3-Color E-Ink Display

This is an E-Ink / E-Paper Display Module 2.9inch with 296x128 Pixel resolution, with an integrated controller that communicates via the SPI interface. The Multi-Color Display supports the three colors Red, Black, and White. Due to the extremely low power consumption, it is great for battery-powered applications. These displays are also used as price tags in retail, where they can be operated for several years with one battery. The display has a very good viewing angle and can be read very well even in sunlight. Since this display is operated in 3 colors, it takes around 15 seconds to build. Therefore, it is of course not intended for applications where the display must be updated every 1s. The package also includes a connection cable with which you can easily connect the display to a Raspberry Pi. For an Arduino Uno or if you want to plug it onto a breadboard, you will need 8 x Male/Male Dupont cables. 

Features: 

• Onboard level converter thus compatible with 3.3V and 5V microcontroller
  
• Displays on the screen remain visible 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
• Programming examples available for the following controllers: Arduino, stm32, and Raspberry Pi
