Hobby-Ace Mini CC3D PDB Power Distribution Board Sub-panels 12V Linear Regulator for FPV Traversing Machine For 36S LiPo used on the Quad copter, Generally the input voltage of FPV camera is 713V, When 4-6S LiPo is mounted, the linear regulator can power the 12V camera 12V LED without ripple noise Mini distributor plate, consumes very little power transfer layer space Use 2oz copper, resistance to high current Comes with 12V linear regulator (buck), solve the use 4S battery to power the camera issue Camera work current is generally only a few dozen mA, voltage regulator chip does not have a great heat
