Power supply input for the UART GPS NEO-7M-C module.
Ground reference for the module and host serial adapter.
UART transmit output from the GPS module. Waveshare connection table maps TXD to host/serial RX.
UART receive input to the GPS module. Waveshare connection table maps RXD to host/serial TX.
Pulse-per-second timing output. Waveshare note says PPS should connect to an MCU clock pulse output/CPOUT use case and is left unconnected for PC serial-adapter testing.
