296x128 2.9inch Black / White 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. This black and white display supports partial updates. Thus, individual areas can be updated quickly within 0.3 seconds. An update of the entire display also takes only 2 seconds. Due to the 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 for several years with a battery. The display has a very good viewing angle and can be easily read in sunlight. A connection cable is included 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 will need 8 x Male/Male Dupont cables. 

Features: 

• Onboard level shifter thus compatible with 3.3V and 5V microcontrollers
  
• Displays on the screen remain even without power supply
