Wemos D1 Mini is one of my favorites ESP8266 boards with a cheap price, tiny form factor, and support for stackable expansion boards.

Lolin has now launched a small 2.13-inch tri-color E-Ink display that is compatible with D1 mini, D1 mini Pro, and D32 Pro boards, and sells for just $9.90 shipped.

2.13-inch epaper color displayYou may wonder why the PCB reads “2.13 INCH e-Paper 250×122”, while the resolution is 212×104. That’s because the company probably reused the PCB from their 2.13-inch black and white e-Paper display with 250×122 resolution (IL3897 driver).

The display can be programmed with Arduino using LOLIN_EPD, Adafruit_GFX, and Adafruit_BusIO libraries as explained in the Wiki. You’ll find three Arduino sketch samples on Github.
