The PDB-100A is a 100A power distribution board made for quadcopter and octocopter set-ups. The listing says it is designed for efficiency and works with advanced flight configurations, giving lightweight durability for high-current handling.
It is built to withstand up to 100 amps and has FMU PWM and I/O PWM outputs for precise motor control, so you can connect up to eight ESCs. The compact circular design has a 35mm radius, which minimises drag and helps integration on a multi-rotor.
The robust glass fibre material is meant to be reliable without adding much weight, and the board weighs only 17 grams.
High current capacity: handles up to 100 amps.
Flexible motor connectivity: supports 1 to 8 ESC connections.
FMU and I/O PWM outputs: for precise motor control.
Lightweight: only 17 grams.
Compact circular shape: 35mm radius.
Premium glass fibre: durable material.
A power distribution board (PDB) takes the current from the flight battery and shares it between the ESCs and other parts of the aircraft. Instead of soldering every ESC lead to a single battery lead, you solder them to wide copper pads on the board, which handles the current safely and keeps the wiring tidy. Many boards also include voltage regulators, so that a flight controller, receiver or camera can be powered from the same board.
When you choose a PDB, check that its current rating comfortably exceeds the total of all your ESCs at full throttle, that its input voltage range covers your battery and that the pad spacing and connectors match your frame and wire gauge. Solder with a hot iron and plenty of flux so that each joint flows, and cover joints with heat-shrink.
Check every joint for cold solder and shorts before you connect a battery, and use a smoke stopper for the first power-up. A small hairline crack in a solder joint can heat up under load and fail, so re-inspect the board after crashes.
