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.
Why Choose the 1203B PWM Motor Speed Controller?
- 100% Authentic: Sourced from trusted, verified suppliers - guaranteed genuine components and reliable performance.
- Beginner-Friendly: Simple hookup with just power supply and motor - no programming, microcontroller, or complex wiring needed.
- Versatile Application Range: Works with brushed DC motors, cooling fans, water pumps, LED strips, and other resistive/inductive DC loads.
- Energy Efficient: PWM control means your motor only draws the power it needs at any given speed, saving energy and extending battery life in portable projects.
- Fast 1-5 days shipping: Ships from our Bengaluru warehouse to most locations across India; same-day delivery available in Bengaluru.
- Expert Technical Support: Our engineering team is available 24/7 via email and WhatsApp to help with wiring, troubleshooting, and project integration.
Project Ideas
- Robotics Speed Control: Regulate wheel motor speeds for differential-drive robots, line followers, or obstacle-avoiding bots with precise throttle control.
- Variable-Speed Cooling Fan: Build a temperature-responsive or manually adjustable fan system for 3D printer enclosures, electronics cooling, or workbench ventilation.
- LED Brightness Dimmer: Use the PWM output to smoothly dim 12V or 24V LED strips for ambient lighting, photography setups, or display signage.
- Mini Water Pump Controller: Adjust flow rates in hydroponic systems, aquarium filters, or DIY water cooling loops by varying pump speed.
- Model Train & RC Speed Regulation: Integrate into model railway layouts or RC vehicles for realistic, smooth acceleration and deceleration.
- Conveyor Belt Prototyping: Control conveyor belt speed in small-scale automation and industrial prototyping projects.
- Educational Motor Labs: Demonstrate PWM principles, duty cycle effects, and motor characteristics in physics and electronics classrooms.
