This would be great to have. With the small size of the board I have wrecked a 5005-0 trying to solder an OLED screen!

I was able to get my 1.54 inch e-paper working, the resolution and screen size appears to be incorrect for the RAK14000 display...

It should be (tested with RAK code sample)
https://github.com/RAKWireless/WisBlock/tree/master/examples/common/IO/RAK14000-Epaper-Monochrome

DEPG DEPG_HP = {250,122,40,20,40,30,40,50,90,40}; //use DEPG0213BNS800F41HP as default

2.13 inch 250 x 122
SSD1680 driver

Also this display is not yet supported by GxEPD2 only a b/w/r version

Ok, so I tested support for what was the e-paper library for a similar e-paper with slightly different resolution but works.
250x128 vs 250x122
The interface layout needs adjustment

[markbirss]

Anyone else want to test and help to fix the layout ?
