How to wire it up
Uart Style:
Because of the Serial port issue of Raspberry Pi 3, Model B, it may cause an unexpected problem, we suggest that you do not connect the GPS module with Raspberry Pi directly with GPIO Pins.
1. You need a USB-to-TTL cable to connect GPS module and Raspberry Pi, and you can wire it up like this chart:
| GPS module | Wire color |
| VCC | Red wire |
| GND | Black wire |
| TXD | Green wire |
| RXD | White wire |
How to use it
- After power on and login to the system. you can open a terminal and typing following command to install packages for GPS module.sudo apt-get update && sudo apt-get -y install gpsd gpsd-clients python-gps
- Reboot your Raspberry Pi and login, also typing the command in your terminal, it will help you reconfigure your gpsd service:sudo dpkg-reconfigure gpsd
- Start the gpsd service:sudo gpsd /dev/ttyUSB0 -F /var/run/gpsd.sock
- you can stop the gpsd service:sudo killall gpsd
- You can also use systemctl command to manage this service,but at the first, you should modify the configuration file of gpsd in /etc/default/gpsd,filling the blank with your device name and socket name and path.
Start service:
sudo systemctl enable gpsd.socksudo systemctl start gpsd.sock- Stop service:
sudo systemctl stop gpsd.socksudo systemctl disable gpsd.sock- Finally, use this command to get information from the GPS module.
sudo cgps -s
Package Included:
1 x Raspberry Pi GPS Module, Using L80-39 Module Program. Support Model A B, PI, A+, B+, Zero, 2, 3
