I have swapped the wires according to the store page (picture below)
But once I connect it to the board and power up, there is no LED emitting from the GPS which should be yellow blinking LED. I have measured the voltage from UART on PXFmini alone it has 5V which is fine. So is it GPS faulty or are there other reasons to this?
Another issue is that whenever I connect I2C from GPS, my ESC stop working and come back working again when disconnecting GPS’s I2C. What happen?
