VCC(+3.3V DC power Input)
This is the main DC power supply input pin. IT provides voltage to module.
TXD (GPS to Host)
This is the main transmitting NMEA data and is used to programming download or debug port. NMEA Format 9,600 Baud rate.
RXD (Host to GPS)
This is the UART receiver port of the module. It is used to receive software commands and If you want you can change Baud rate, Static Hold, assistnow autonomous…
GND
GND provides the ground.
