Adding GPS to drone

[Kitch71]

Can I add gps to my self build drone Mamba F722S FC? Would like position hold and return to home features if possible.

Maybe... Does it have a free uart (RX tx pair) and does it have spots for SDA and SCL (i2c bus for compass) if so you should at least be able to hook one up. I believe return to home is a thing in Betaflight but more advanced GPS control you're better off with inav (from what I hear exploring this myself now too)

Interesting will look into inav, I have just hooked a gps up to my quad and the gps seems to be working in Betaflight but compass is not showing as yet. I have remapped Uart for SDA and SCL for the compass. I am new to all this so its a steep learning curve.
