UART GPS Module, u-blox NEO-7M-C, Curved/Horizontal Pinheader
u-blox NEO-7M-C GPS module with UART output. Available in curved or horizontal pinheader orientation; provides NMEA position data at up to 10 Hz update rate.
Pinout
- VCCModule header pin labelled VCC
Power supply input for the UART GPS NEO-7M-C module.
Type · PowerVoltage · 2.7V to 5.0V input, wiki connection table shows 3.3V/5V. - GNDModule header pin labelled GND
Ground reference for the module and host serial adapter.
Type · GroundVoltage · 0V - TXDModule header pin labelled TXD
UART transmit output from the GPS module. Waveshare connection table maps TXD to host/serial RX.
Type · UARTVoltage · TTL UART level, powered from VCC - RXDModule header pin labelled RXD
UART receive input to the GPS module. Waveshare connection table maps RXD to host/serial TX.
Type · UARTVoltage · TTL UART level, powered from VCC - PPSModule header pin labelled PSS/PPS in Waveshare table/note
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.
