Drill and tap
We finished drilling and tapping all the holes for the GPS, ATV, WiFi and WiFi PA and they are all now attached.
GPS Side
Other Side
We also routed some of the USB cables from the FC board's connector to the GPS board and one lower for an eventual IMU to be installed.
There are now only two USB ports open, one will go to the WiFi and the other will need to go to a hub.
