Forward and reverse control The motor direction is determined by the control port: the motor runs CCW when the port is not connected, and runs CW when the port is connected to a low level (less than 0.6 V). This provides simple direction control with minimal wiring. MicroDC PWM speed controller Uses pulse width modulation to regulate motor speed with precise, smooth control and fast response to changes in duty cycle. Reverse speed control Reverse speed is regulated through PWM mode; at maximum speed, the connection to the power supply negative pole achieves the strongest reverse performance. Power input wiring Red wire is the motor power positive input, establishing the positive power connection for the motor. Compatibility and setup Designed for direct connection to DC motors using a single control signal for direction and PWM for speed. Sensitive to lowlevel control signals (below 0.6 V) for direction switching. Use scenarios Simple robotics projects: connect to a microcontroller or control circuit to set direction via the control port and adjust speed with PWM for precise motion. Educational PWM demonstrations: observe how varying PWM duty cycle changes motor speed in forward and reverse modes. Small DIY devices: implement compact motor control for fans, conveyors, or hobby machines where lowcost, straightforward PWM control is beneficial.
