Wemos D1 Mini is one of my favorites ESP8266 boards with a cheap price, tiny form factor, and support for stackable expansion boards.
- 2.13-inchTri-Color (red/black/white) ePaper/e-Ink display with 212×104 resolution
- Driver IC – Good Display UC8151D
- Connection to D1 mini, D1 mini Pro, D32 Pro via 10-pin connector
- Debugging – 8-pin unpopulated header with EPD signals (SPI, Reset, Busy…) 3.3V, GND
You 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).
