Just 'Cuz Robotics has designed a helpful, functional, compact, lightweight PCB to make wiring your bots, simple, easy, and less error-prone. In addition, this version incorporates a screw power switch, 5V BEC, power indicator LED, and a convenient 3 pin header for connecting a receiver.
What's included per purchase:
One (1) board with a pin header, 5V regulator, LED, and related SMD components preassembled
One (1) Tin plated steel #8-32 press insert nut, pressed into the power switch hole
One (1) #8-32 Button Head Screw for the power switch (3/32" hex drive just like Fingertech switches use!)
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 500mA
(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.
SW pad to run wires for an external switch/link, bypassing the included screw switch - just connect one switch side to the big top circular pad, and the other to SW
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 M2 mounting screw holes to hold down the board or attach a cover
Size is about 34.5mm x 26.5mm or 1.36" x 1.04"
Weight of ~10.8 grams (0.38 oz) assembled
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. 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!
