E-Ink Display pHAT – 2.13inch (250×122)

Looking for an eInk / ePaper display for your Raspberry Pi or Raspberry Pi Zero? Look no further! This great little black/white eInk/ePaper display from Waveshare is perfect for adding a low-power display to your project.

Also available in yellow/black/white and red/black/white! User Guide here!

ePaper / eInk displays are designed to replicate the appearance of ink on paper. Unlike regular displays, which lose their image when power is removed, eInk screens are able to hold text and images indefinitely, even without power. ePaper screens are therefore ultra-low power, designed to have a wide viewing angle and additionally have limited reflection under sunlight. The applications are limitless!

The E-Ink display modules from waveshare come complete with an embedded controller PCB, communicating via SPI interface, and support partial refresh.

This module includes a 2.13″ (250×122) eInk display & pHAT PCB format, designed to plug directly onto your Raspberry Pi Zero or Zero W.
