Hi guys,
I just got an A16 board. I read the design review (https://www.kincony.com/esp32-board-16-c...dware.html) but I didn't really find any proper solution to connect RX / TX UART TTL pins to the board (for my R503 fingerprint sensor).
Could someone please help me how to connect that sensor / use UART with that board?
Thanks and best regards!
Stefan
