Designed in house by the HobbyKing Enginerds, this handy power distribution board has the same foot print as our Multri-rotor control boards and is the ultimate solution for tidy power distribution wiring. Simply use 3.5mm male connectors on your ESCs and plug a battery in. The PCB is Gold plated for optimality efficiency and also features a bling port (aka 2 pin JST size auxiliary power out) Perfect for powering LEDs or any accessory fitted to your Quadcopter.
Features. Current: 4 x 20A Outputs (MAX) Power Input: XT60 with 12AWG wire Motor output: 4 x 3.5mm Female bullet plug Aux output: 2 pin JST compatible Weight: 27.3g (including wires)
It's a JST 12 volt accessory plug. You can use it to power LED lights or supply 12 volts to anywhere you like. If you had a Y adapter you could send one end to a KK board to monitor battery voltage and the other end to LEDs or whatever you choose:). The control board receives its power from the ESC's connected to the motors. Look , Hardware & Accessories>Wires&Plugs>Battery and you will find these JST plugs and plugs with wires to use for this.
Good product though quite heavy. Nice when you exchange your escs one in a while to other quads because you dont have to de-solder the leads from normal power distr boards. To be used with larger quads, not for mini/micro quads. I will mod mine with XT60 connectors instead of the 3.5mm bullits as I use these as a standard with escs. I like the optional LED-outlet.
Good board, simplifies the connection of ESCs, however for me, I preferred to desolder the connectors of 3.5 mm and weld Nylon T-Female Connectors. Can always extra welding points empty, for example a Bec.
