My biggest Problem with these devices is

a.) the world of electronics is moving too fast

b.) My lack of skills and time to build something really cool with something like this

A while ago i bought a licheerv nano (similar to luckfox pico or Milk-v duo) to build an open source iPod nano via usb-c audio Jack and the open source buildroot for the licheerv nano.

I did not find a suitable 2.4 inch or at least < 3"touch display that worked with the integrated MPI port.

With LVGL it should be doable to build a small portable audioplayer with acceptable features... But not for me :-)
