Power Distribution Boards (PDB) are essential for Quadcopters, they take the power coming from your battery and split it between all the ESCs and other equipment on your quad.
These PDBs are great and can be stacked below a Naze 32 or CC3D when using nylon stand offs (see images)
This PDB has:
6 pairs of larger pads for attaching larger items such as your battery wires and ESC.
6 pairs of smaller pads for connecting servo/jst size wires for things like FPV equipment and LEDs
