Key Features
- Wide Voltage Compatibility: Operates from 6V to 28V DC, supporting a broad range of motor voltages including 6V, 9V, 12V, and 24V systems.
- Smooth Stepless Speed Control: Onboard potentiometer provides continuous 0-100% duty cycle adjustment for precise, jitter-free motor speed regulation.
- High-Frequency PWM (~20 kHz): Operates above the audible range, eliminating annoying motor whine and ensuring silent operation.
- 3A Continuous Current Handling: Capable of driving small to medium DC motors, fans, pumps, and LED strips without external drivers.
- Ultra-Compact PCB Design: Tiny footprint makes it easy to embed inside enclosures, project boxes, or tight spaces in robotic assemblies.
- High Efficiency with Low Heat: PWM switching design minimizes power loss compared to resistive speed control, keeping the module cool during extended operation.
- Easy Screw Terminal Connections: No soldering required for basic setups - simply connect power supply and motor via screw terminals.
- Reverse Polarity Awareness: Simple two-wire interface reduces wiring errors; clearly labeled input/output terminals.
