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.
I'm using the 30amp afro simon k escs with the NTM Prop Drive 28-26 1000KV / 235W which have a max current draw of 15amps. Should i use a 20 amp ESC instead? Would a 20 amp ESC be enough for those motors?
You can use this board if your motors do not use more than 20A EACH for a longer time period. As you have 4 motors you can use it safely with 80A of current draw. I use this board on my quadcopter too and I get current draws of up to 100A and did not have any problems with the board until now. The "discharge outputs" from the batteries you mentioned just tell you how much current your batteries can deliver for a longer time period without beeing damaged. How much current you really draw depends only on your motors/speed controllers.
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.
