Just nearly finished my build . Using Matek F7 on a Matek F Chub with VTX.
Problem 1. the flight board wo’nt connect consistently to betaflight . Sometimes it flashes blue/ red and sometimes just red. Very intermittent communication . Also the Fchub is all red, and the flashware not updated form original.
Second. Not sure what cable is what on the avi out cable from the Go Pro . Its black/red /black /yellow.
Very frustrating as there is no LED guide that I know of to tell you what is what when it comes to the boards.
Could it be the communication between the 2 boards . Is the red only on the F7 meaning its just picking up 3 volts, and why is there no blue light on the FCHUB.
Should I power the board directly via the 5 volt link, regardless of the fact that the ribbon connector is meant to send 5 volts ?..isn’t it ???
