I use it with PICOPlus2W (with bluetooth classic) and a Waveshare 3.5 inch display screen as a mini DOS system (code based on zero86 but not made public yet). It is particularly nice with such a small system because it is not much bigger than the 3.5 inch screen. It works well but it lacks function key and the tab key. I overcame that by adding some key translation in the bluetooth bridge code found on the Adafruit site - and adapted for my use.
