I'm using one of those devices with a tiny eink screen... as a pocket ebook reader. Sorry for the bait. Fun and easy project though, lookup Pala one if you're interested and dm me for improved firmware (restrictive license)
Sounds intriguing. How is the battery life? Color e-ink or BW?
Would be great if it also ran some type of Topo mapping software!
BW. I don't think colour would do much, as the screen is 250x122. Battery may depend on what you can find, but the one I have should last several weeks (still testing). I started on a tiny LiPo I ripped from my cat's floppy fish toy.
To give more info here, it uses Heltec Wireless Paper, which is a self-contained unit and just needs a battery added.
