Anyone tried one of these? I'm thinking it would be a good platform to test operating systems - particularly android as I'll be able to hook it up to one of my OK pc monitors.
rpi is probably our best bet for a diy e-ink system. https://github.com/aceisace/Inky-Calendar
or stm32 https://hackaday.io/project/11537-nekocal-an-e-ink-calendar
I have a 2.5" one and it's great. 2 sec refresh, snaps right on a pi. seems the big one has a 15+ refresh though
