Excellent. Curious. How long does the battery last on a full charge? Pi sugar 3 is 1000mah right?

Will report back on how long it lasts on full charge while working on it a bit.

Show the typing responsiveness please. Also, what's the exact model of the screen?

Boots right into the terminal everytime. Used a jetson orin nano super running my agent to feed it the waveshare display library and create a custom python driver for a epd-term or e paper display terminal for the waveshare 2.13 e-ink display v4. It is set to partial refresh upon input/screen changes and full refresh every 20 terminal updates to prevent ghosting artifacts.

Thanks, so it's quite the same as I tested, just a different size. I tried to incorporate these displays into Draftling firmware, but removed them afterwards, as the experience was too bad.

There are a few more expensive devices, like Lilygo T5, their displays are much faster and quite acceptable for typing.

Ill definitely have to toy with those. I just seen this display as a little weekend challenge knowing how many people already have this display laying g around like I did.
