The wiring of the GoPro GPS module to the flight controller is very similar to other GPS modules, there are four connections: 3.3V, GND, TX and RX. The GoPro GPS module takes 3.3V as input voltage, and it connects to one of the spare UART on the FC (TX to RX, RX to TX).

Would you please give more details about the external HW interface between GPS and phone and about the app shown on the phone? Thank you.

The OP is using the Speedybee app on an Android phone which is similar to the Betaflight configurator and connects to the FC via a usb/otg connection.

The phone is not directly interfacing with the GPS but rather via the FC as seen in the lower left corner of the image.

The external HW interface between GPS and phone: it is just a Flight controller That name is SucceX Micro F4 V2.1 15A 2-4S Flight Tower System (MPU6000,ESC Plugs) From iFlight Company.
The name of application shown on the phone is Speedybee that is ready to download on CH Play. You can get and already use it free on your android phone.

Thank you for your useful details dsminhthe. Sorry for the delay, I was on holiday. I had been looking for SpeedyBee on Play Store but it didn't appear. It was my phone actually. On another it worked. That's why I asked. Nice flights.

Anyone who can confirm this works?

I tried this exact pinout and made sure 3.3 V is going to the said pins.

But no GPS detected on Betaflight at UBlox.

I even swapped rx and tx pins, just to make sure in case the OP meant FC pads (on the GPS) instead of GPS rx and tx.


Any help would be greatly appreciated?
