The King of Space Efficiency in Combat Robotics. All-In-One on Steroids! Motherboard V4 redesign is here! Lighter weight, shorter, better than V2 and in the same footprint. Pair with our new Speedy Brushless Servo! 3D model access is included here! And a quick reference user guide can be found here. You can also find a 3D printable soldering jig here. The Motherboard has been specially developed for use in our SSP Kit, but can find use in many other small combat robots in the antweight (1lb) and beetleweight (3lb) weight classes. This board combines the functionality that typically would come from a myriad of discrete components, saving you weight, time, space, money, and improving the repairability and cleanliness of your robot’s internals. This is NOT a replacement for ESCs. But it will make the wiring clean and compact! Specs Specs and Features: Convenient mounting points for up to four XT30 or XT30U connectors! Battery, Servo, Drive, Weapon, Another weapon? (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 4.5-Amp high voltage BEC capable of handling powerful hobby servos! Input voltage 9-30V or 3-6S, and the SB bridge will create 7.4V for a servo Built-in screw switch to disconnect battery voltage from all devices (tested at 32A for 3.5 minutes, 50A+ for 30 seconds, 100A+ for 3 seconds) Convenient bright power LED Onboard receiver direct mount for FS2A and similar receivers Separate 5V-only BEC dedicated to the receiver! Power the receiver and still get all 4 signal channels broken out for devices and ESCs Current rating: massive copper traces on both sides for increased current-carrying and heat dissipation. Anything an XT30 can take, this can too! Convenient 3.8mm M3/#6 mounting screw holes to hold down the board or attach a cover Size is about 49.5mm x 28.4mm or 1.95" x 1.12" Weight of ~12 grams (0.42 oz) assembled (V2 was ~18g) Clear labels for all components and pins for easy assembly and troubleshooting 3D model access is included here NOTE: a precharge circuit is recommended >4S, and additional solder on top of the circular pad under the screw head is highly recommended at >3S NOTE: As of October 2024 V2 has been discontinued, with V4 replacing it. V4 is a drop-in replacement with two major changes - V2.2 used an off-the-shelf DC-DC converter module that was big, heavy, and stuck up from the board. V4 has done away with this; instead, a custom Just 'Cuz-designed 4.5A 7.4V regulator is integrated seamlessly. There is no more solder bridge needed, the servo BEC only outputs 7.4V and it is sized to handle even our super powerful Speedy Brushless Servo.
