This is awesome! I shall definitely be buying some of these :)
Had a quick look at the data sheet, it appears the RT5350 has one full UART and one "UART lite", but these are not exposed on the HLK module. The bga chip is not very DIY friendly, and I've no idea where to buy the chips anyway.
There appear to be other modules based on RT5350, so perhaps one of those will have alternative features.
