Complete guide to connect and program NEO-6M GPS module with Arduino

NEO-6M GPS module with Arduino

Neo-6M is a very popular Arduino comfortable  GPS receiver with a powerful ceramics antenna. The connection and code are simple. There are enough resources and libraries available for the NEO-6M GPS module.

NEO-6M GPS module pinout

The pinout of the ublox NEO-6M GPS module is very simple. There is 4 pin 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 which comes with the module. The operating voltage of the NEO-6M is from 2.7 to 3.6Volt. But there is a voltage regulator integrated with the NEO-6M. SO we can supply 5volt from Arduino 5Volt pin directly. The GND pin goes to the Arduino GND pin. 
Now connect TX and RX pin to Arduino digital pin 3 and 4 following as the code.

NEO-6M GPS Arduino Code

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