Hi,

I'd like to set up H-RTK ZED-F9P Ultralight GPS with RTK with the VOXL2. I'm planning to plug this into the VOXL's J19 port using the GPS unit's 6/8 (VCC, TX, RX, SCL, SDA, GND) pins into the VOXL's first 6 pins. Does this sound like it should work?

Thanks

@alan123 , yes, the 12-pin connector on VOXL2 (J19) was designed such that the first 6 pins are compatible with a lot of existing GPS recevier modules. Please double check the pins and you should use a 12-pin connector to plug into VOXL2 (may need to re-pin your cable).
