I'm interesting your board. we find embedded board that has more than GPIO
20 pin and already loaded android OS. And we want 10'' touch panel. I saw
many your product through Aliexpress, board spec is good but touch panel
size is too small. Will you recommand me a good board?
And lastly, Can you provide GPIO porting software or library for android
programming?
If we finish development our machine, we have a plan mass production. So I
want your reply. Thank you.
