Drone PDBs, BECs & Capacitors
Drone PDBs (power distribution boards), BECs and capacitors distribute and clean up battery power. Power modules add current sensing for the flight controller, BECs step pack voltage down to 5V, 9V or 12V for cameras, VTXs and servos, and capacitors absorb voltage spikes. Size a PDB or power module by current and cell count; size a BEC by output voltage and amps, with a margin over the load. We stock Mateksys, TBS, Holybro, Mauch, iFlight and Flywoo. For steady 5V rails, see BECs & Voltage Regulators.
