Specifications Just ‘Cuz Robotics Long All-in-One Power Distribution Board Parameter Spec Length 57mm, 2.24″ Width 14.4mm, 0.57″ Thickness 13.7mm assembled, 0.54″ Weight ~8.4g assembled (0.3oz) ea. ~4.2g unassembled, (0.15oz) Included as part of the assembly: Qty 1 (one) Long All-in-One Power Distribution board with 5V regulator, LED, and related SMD components preassembled Qty 1 (one) Tin plated steel #8-32 press insert nut, pressed into the power switch hole Qty 1 (one) #8-32 Button Head Screw for the power switch (3/32″ hex drive just like Fingertech switches use!) Long All-in-One Power Distribution Board Features: Convenient mounting points for up to four XT30 or XT30U connectors! Battery, Weapon, and two drive sides (I recommend using Male for Battery and Female for others on the board) Clearly marked orientation for connectors to avoid reverse polarity ruining your parts Use any connector or combination of direct soldering and connectors 5V BEC capable of handling input voltages of 6.5V to 36V (2S to 6S LiPo recommended) to power a receiver or other 5V devices up to 100mA (NOTE: a precharge circuit should be used above 3S, and additional solder on top of the circular pad under the screw head is recommended) Built-in screw switch to disconnect battery voltage from all devices (tested at 32A for 3.5 minutes, 50A for 30 seconds) Convenient bright power LED for power indication 3-pin servo connector compatible header for RX connection When the screw is tightened, this connects battery positive to all other connector positive terminals, sends 5V power to the receiver header, and turns on the power LED. (SW pad to the top circle pad must be shorted with 18AWG or larger wire for testing/use without a switch/link.) Massive copper pads on both sides for increased current-carrying and heat dissipation Can connect as many other devices as you wish to the copper pads under the board – no need to use just four! No need for a messy wire ‘squid’ to wire all your ESCs! Convenient M3/#6 mounting screw holes to hold down the board or attach a cover Clear labels for all components and pins for easy assembly and troubleshooting WARNING: The bottom of the board has exposed copper regions that, if in contact with a conductive surface, can short circuit. NOTE: Do not secure this board directly to a conductive metal plate, and ensure that an insulative spacer (electrical tape, hot glue, 3D printed plastic cover) is used before connecting a battery if resting on a conductive surface. These regions are exposed to allow easy soldering to the underside of the board, but they are separated for a reason! NOTE: a precharge circuit should be used above 3S. NOTE: additional solder on top of the circular pad under the screw head is recommended. NOTE: Operation with a battery at a higher voltage than 6S, or drawing too much current from the BEC without added cooling, may result in damage to the 5V regulator. It can be replaced by an off-the-shelf part, Contact Us for more info. NOTE: While this PCB is designed to safely operate inside a combat robot, it may get very hot. Touching it during, or shortly after operation, can result in serious burns. NOTE: In the unlikely case where you have difficulty turning off the switch while it is hot, waiting 30-60 seconds for it to cool should resolve the issue. NOTE: Just ‘Cuz has gotten word the switch can be hard to turn on if the board is flat against a baseplate without a proper spacer. This is because the screw is a bit longer than needed. Sanding off about 1/32 inch from the threaded side should fix this. Testing a robot with an active spinning weapon should never be done while maintaining a line of sight with the robot. Ideally, you should be testing inside an enclosed box or arena with at least 1/4″ thick polycarbonate windows or top to see through, and 1/2” or thicker plywood or MDF construction.
