My pet peeve with RasPi for these types of handheld projects is that they don't support suspend, and don't have a true poweroff state. Even in poweroff, they sit there consuming a bunch of current.

Beepy is a similar project that uses a RasPi Zero, and their approach is to cut power to the RasPi entirely with a management MCU. On my Beepy, I switched to a Radxa Zero instead and ported over any relevant kernel modules and device tree overlays, because it has an Amlogic SoC that actually supports suspend.

Am I right in assuming it's fairly straightforward swap hardware wise? Do you have any measurements of the difference in battery drain between the two? Is it a fairly recent kernel?

With that Sharp memory LCD and proper suspend that's potentially a gamechanger for the beepy. Any direction you can point me in appreciated.

Hey, sorry for the late response. I posted my notes here: https://github.com/Hylian/beepy-radxa-zero-notes. It's a straight swap hardware-wise, and for software, you just need to build/install the kernel modules and configure some kernel boot arguments.

Feel free to ask in the Discord if you have any questions.

Ditto. I’ve wanted to get a Beepy for a while, and I have a Radxa Zero already.

what is better? for ssh?

I'd love to learn more! I'm one of the Beepy creators...I just emailed you
