Nice, but I prefer something slightly more Powerful like the Unihiker with a Rockchip 3308 (https://www.dfrobot.com/product-2691.html, https://www.youtube.com/watch?v=EmBhBfV3Kfw) or the Funkey S (https://www.funkey-project.com/) with an Allwinner V3s... or even the non open X-Boy Plus (https://github.com/hsinyuwang/X-Boy) with Allwinner T113-S3.

I'm still keeping an Eye on these device types because someday I hope it will be possible to create my personal Audio Player / iPod Nano clone with Wifi and long battery life by putting a buildroot based image (https://github.com/FunKey-Project/FunKey-OS) and Running a C# or Flutter UI on the framebuffer (https://docs.avaloniaui.net/docs/guides/deep-dives/running-o...)

I think Mango Pis Cyberpad 1 is pretty close to my wishes, but I haven't had the time to check it out :-) https://mangopi.org/cp1m
