Power Distribution board)are often an overlooked area of multirotor drone building, mainly because they are fairly simple but despite this, they are a crucial part of your drone and if you don’t choose the right one you could end up losing your drone.
As the name suggests, a PDB(Power Distribution board) distributes the power on your drone and provides a neat and tidy way of connecting your battery to all of your ESC’s on your aircraft. A PDB(Power Distribution board) has positive pads/terminals which are all connected and negative terminals/pads which are all connected. This way when you solder all of the red wires from your ESC’s and battery to the positive pads on the PDB, and the black wires to all the negative pads, they will all become connected so your battery can provide power to all of your ESC’s as shown in the image below.
