The Wemos mini32 D1 board offers many I/O pins, so it was a challenge to see
this unit used in the in popularity growing WIO concept.
Due to a fault in the original datasheet, the TX and RX connections of UART1 connectore are swapped.
This is mainly no problem, but it differs from serial connectors on other WIOxx boards.
