Pix32 v6 Pix32 v6 Baseboard Ports

Pix32 v6 is compatible with Pix32 v5 Baseboard and vice versa.
Due to the difference in Pin map, the following ports shaded in red in the diagram below will be non-functional when using a Pix32 v6 FC on a Pix32 v5 Baseboard.

Pin 1 starts from the flight controllers "Left side". All connectors are JST GH 1.25 mm Pitch unless noted otherwise.
