Top position must be used when external WT12 module’s nCTS and RxD pins are
interfaced trough J2 connector.
Bottom position must be used when WT12 is interfaced trough the DB9 RS232
connector.
nCTS connects to pin 10 on the GPIO (J2) interface
RxD connects to pin 14 on the GPIO (J2) interface
nCTS connects to nCTS-UART
RxD connects to RXD-UART
