Can you connect a keyboard?

@stack Yes, you can do that. This is just a little Linux computer after all. It sort of defeats the purpose of having a little portable handheld, though, if you need a separate keyboard to type...
I get it, but I do like the idea of an amazingly portable device but have an option to use the keyboard when it fits the task...

Hmm, I suppose a cute little travel keyboard that connects via Bluetooth wouldn't be too bad to carry around. While you could jam the RGB30 in a pocket, it's not that comfortable, so some kind of a bag situation is needed anyway.
(I'm typing this via Bluetooth on the RGB30.)
Very nice. Is that screen keyboard part of Lagrange, or is it separate program?

It is part of Lagrange. The system can't show multiple programs at once due to there not being a window system present.
Amazing! How did you develop the application for this? I have a few of these, am a programmer, and am familiar with linux but don't know how I would get to the command line on one of these. I have a Powkiddy and two Anbernics.

@donsta The Powkiddy runs JELOS, which is basically a minimal aarch64 Linux distribution. I didn't bother looking for a cross-compilation toolchain, but instead chose an aarch64 Debian from the same time period (2023, I think) and ran it in a VM. In this Debian VM, I did a normal Lagrange build. I statically linked most dependencies, and thankfully the ones that had to be dynamic were compatible enough to work when they got loaded from JELOS instead of Debian. I also did a custom static build of SDL2 with support for the Rockchip GPU. All in all, a little hacky but it only took a few days to work out the kinks.

First post from my RGB30 Linux handheld console. As suspected, typing on this new on-screen keyboard is tedious, but it works! I've got Lagrange running on this thing, obviously. :)
