Looking for an eInk / ePaper display for your next project that does not require a Raspberry Pi or Raspberry Pi Zero host? Look no further! This amazing little stand-alone black/white two-color 2.13" eInk/ePaper display from Waveshare is perfect for adding an ultra-low-power display that can be updated via a remote webpage or an app on your Android device.

ePaper / eInk displays are designed to replicate the appearance of ink on paper. Unlike regular displays, which loose 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!

This 2.13" E-Ink display module from Waveshare comes complete with an embedded controller PCB, communicating via SPI interface, and supports partial refresh.

This module includes a 2.13" (212x104) eInk display with an embedded ESP32 and utilizes an Android App for refreshing the image on the display.
