Hi and thanks for the guide! I wonder if this pin layout is right, I opened the Type C plug of the cam to find this:
Red covered cable on A2 (white), A3 (blueish) and the two strains of the green covered cable on B10 (blueish) and B11 (white). I think this would invert the polarity of the TX and RX cables in your sketch but also which cables belong to TX and RX, right?
