The code needs more work but I'm really pleased with my #Inkplate6Color display showing a few Google calendars for the next few days
About a month ago I bought a crowd funded colour eInk display on a whim without a plan:
https://www.crowdsupply.com/soldered/inkplate-6color
It's turned up sooner than I expected, has good docs/examples and seems easy to use. It's currently displaying a picture it downloaded from the web.
I'm impressed - time to buy a battery for it and come up with a plan.
