How to connect 5 pin GPS serial connector?

Sun Jul 16, 2017 4:20 pm

I'd like to connect a GPS board (see product link below) to a Pi3. The board has a 5 pin GPS serial connector (GND, 3.3V, TX, RX, 5V pins). What is the easiest way to connect the board? Once connected, what will the device name be (e.g. /dev/ttyAMA0)?

Finally, I'd like to tuck the GPS board inside the Pi's case. What is the best way to insulate the GPS board from the Pi?

Foam pads or sticky pads have worked for is to separate the pi from things, incl. GPS modules.
I'm sure bluetak and gaffer taper would be just as good.
Seems quite expensive for a GPS module though..

Anyway TX to RX's and vice versa and 5v to 5v gnd to gnd.
May as well do 3v3 to 3v3 if it needs it.

Enable serial port and disable the console in raspi-config

And you should see it on /dev/serial0

Assuming an up to date Raspian setup.

Thanks!

Actually this is the lowest cost board that I've found with a high precision GPS chip. The ublox NEO-7P has built in RTKLIB capability and can be configured to output PPP (precise point positioning) which enables sub meter accuracy.
