120A DIY Octocopter Power Distribution Board and Dual UBEC

This power distribution board (PDB) is a 3-in-1 device that simplifies even the most complicated multirotor builds.

The PDB has two built in UBEC’s; one set at 5 volts, handy for a flight controller or receiver and the other adjustable from 10-20 volts, perfect for powering lighting, servos and other gear. The board even features integrated LED’s that illuminate when you plug a battery in.

With this board, even if you’re building an octocopter you won’t be stuck for connections. There are 12 positive/negative pads (8 large, 4 small) for power distribution and also four outputs for each UBEC. Best still, unlike many inferior boards this PDB can handle high Amps thanks to its 4oz copper construction, up to 120A to be precise. The UBEC’s are just as impressive being rated for 5S high voltage setups. Finally when it comes to mounting the board, the standard M3 45mm spaced holes make it easy to mount to most multirotor frames.

Please note that basic soldering skills are required to construct this board – see the assembly instructions for further information and the required equipment.
