This motor speed controller is a compact, easy way to control the speed and direction of a brushed DC motor! Just plug in your motor, a battery (between 9V and 30V), and a receiver to get your motor moving. Wiring ReceiverIf you are using an R/C receiver, simply plug this 3-wire connector into the desired channel. The built-in 6V BEC (which can supply 6A continually) will power your receiver via the red wire. It can also be plugged into a servo controller or an Arduino (via jumper wires) or anything that can produce a PWM signal. It responds proportionally to a signal between 1100 - 1900 microseconds. This range was chosen to allow most standard radio systems to achieve the full motor power without reprogramming. 9-30V InPlug a battery or power supply (9-30V) into the XT30 connector. XT30 connectors are keyed, which prevents them from being plugged in backwards. MotorIf you are rocking a Yellow Jacket, Saturn, or other motor which has 3.5mm bullet connectors, just plug it in! If your motor does not have bullet connectors, check out our bullet connector leads and adaptors. Brushed DC motors are reversible so you don't need to worry about plugging it in backwards. If the motor spins the wrong direction, just swap the red and black wires. Mounting The case has four holes, spaced on a 32mm square. This allows the motor controller to align with the 8mm grid pattern found throughout the goBILDA® lineup of parts. M4 attachment hardware is included to help you fasten it down to your project. If you have multiple motor controllers, you can stack them using longer M4 screws. If you're not working with goBILDA® parts, and just need to fasten the motor controller to a surface that is void of any holes, use the case as a template to mark the proper hole locations. The mounting holes have a 4mm diameter which is also compatible with #6 (yes, imperial) screws if your DIY project has you digging through random bits of hardware to piece your project together. Protection The board has safety features built in to protect it from silly wiring errors and/or punishment beyond what it should be asked to hold up to. While the XT30 connector itself is keyed, we know that sometimes input connectors get removed and/or replaced, so we added reverse-voltage protection. The board also has over-current protection that will kick in if your motor is pulling so much current that there's risk of damaging the board. In a similar fashion, if the motor controller gets too hot, it will shut down until the temperature reduces to a reasonable level. The case itself is another line of defense, protecting the electronics within from physical abuse as your project gets bashed around. Safety Features Reverse-Voltage Protection Over-Current / Short-Circuit Protection Over-Temperature Protection Signal Arm Zone Status LED The status LED communicates the motor controller's status via Blink Codes. These light sequences are colored according to Good, Warning, and Fault statuses, and their blinks help to indicate Over-Temperature and Over-Current events, as well as signal and arming statuses. Refer to this chart to know the specific status communicated by each possible pairing of color and Blink Code.
