Matek FCHUB-12S V2 PDB is a power distribution board for high-performance drones using separate ESCs. It supports 3–12S batteries and handles continuous current up to 4× 70A (peak total up to 440A). The PDB features a current sensor up to 440A, a 12V/4A BEC with a switchable 2A output, a 5V/5A BEC, and a voltage divider. The board has standard 30.5×30.5 mm M3 mounting holes. An 8-pin connector is available for easy connection to a flight controller. The FC can be powered either directly from the battery or from the 12V BEC (selectable via solder pads).
