I got a pressure mount hat from here, because I suuuck at soldering.
Pressure mounting is a bit finicky so you have to eyeball it and make sure all the pins are more or less at the same depth.
(I also belatedly realized the Raspberry Pi Zero WH includes the soldered-on headers for a few more bucks, $18 vs $27, I should have just done that in the first place! I also noticed this stuff is a bit more expensive on Amazon versus the “official” vendors like Canakit)
The e-ink display docs are here, and they work. I skipped the Python 2 stuff though.
(click on “hardware / software setup” tab at the top, scroll down to the Raspberry Pi section)
This e-Ink module is marked V3, rev 2.1, and I think 4 line SPI?
so the example python file I used included V3 as well as the dimensions of 2.13 inch. After some pressure mount pin nudging, I got both to work!
