Warning! We have received several reports about the Matek PDB. It appears that the Matek is not supplying sufficient power to the board (even if specs say otherwise). Usual symptoms are video outages or OSD disappearing during heavy maneuvers. We thoroughly tested with the Pololu 1A BEC (D24V10F5) and recommend to use it. https://www.pololu.com/product/2831
