NEO-6M GPS module pinout

The pinout of the ublox NEO-6M GPS module is very simple. There are 4 pins available. The module communicates with the microcontroller using the UART communication system. It also supports USB and Serial Peripheral Interface (SPI). 

  • VCC - 5volt
  • GND - Ground
  • TX - Transmit
  • RX - Receive

Connecting ublox NEO-6M GPS module with Arduino

As we already know the pinout of the NEO-6M GPS module, we can now establish the wiring between the NEO-6M GPS module and Arduino. We can start the connection by connecting the antenna with the module. The operating voltage of the NEO-6M is from 2.7 to 3.6 volts. But there is a voltage regulator integrated with the NEO-6M. So, we can supply 5volts from Arduino 5Volt pin directly. The GND pin goes to the Arduino GND pin. 
Now connect TX and RX pins to Arduino digital pins 3 and 4 following the code.

NEO-6M GPS Arduino Code

There is a Library for the NEO-6M Module called TinyGPS++. There is another library that needs calling software serial. Once the installation is finished, we compile and upload the following code to get GPS data in the serial monitor.
