296x128 2.9inch 3-Color E-Ink Display

This is a 2.9 inch E-Ink / E-Paper display module with a 296x128 pixel resolution, featuring an integrated controller that communicates via the SPI interface. The multi color display supports the three colors red, black, and white. Due to its extremely low power consumption, it is ideal 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 still be read clearly in sunlight. As this display operates in three colors, it takes approximately 15 seconds to refresh. Therefore, it is not suitable for applications where the display needs to be updated every second. The package also includes a connection cable that allows you to 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 an additional 8 x Male/Male Dupont cable. 

Features: 

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