The 5V to 35V 5A PWM DC Motor Controller & LED Dimmer Module is a versatile power management solution designed for variable speed control of DC motors and power regulation of high-brightness DC LED arrays. Utilizing high-efficiency Pulse Width Modulation (PWM) technology, the module rapidly pulses power at a fixed switching frequency of approximately $20\text{ kHz}$. This ensures smooth power modulation across a $1\%$ to $100\%$ duty cycle range while delivering maximum torque and minimal thermal dissipation compared to traditional linear regulators.

Capable of operating across a broad supply range of $5\text{V DC}$ to $35\text{V DC}$, the board safely handles continuous load currents up to $5\text{A}$ and peak output power up to $90\text{W}$. It incorporates a standby disconnect feature (default jumper setting) that prevents unintended output enablement upon power connection. The onboard rotary potentiometer provides linear duty cycle control and includes an integrated click power switch to shut down the load completely.

Key Features and Benefits

• Wide Operating Voltage Range ($5\text{V}-35\text{V DC}$): Directly compatible with standard $5\text{V}$, $9\text{V}$, $12\text{V}$, $24\text{V}$, and $30\text{V}$ power sources or battery packs.

• High Efficiency PWM Control: Delivers up to $90\text{W}$ output power ($5\text{A}$ continuous) with minimal thermal waste.

• Dual Functionality (Motor Driver & LED Dimmer): Functions equally well as a motor rotational speed governor or a flicker-free DC LED brightness dimmer.

• Integrated Click Power Switch: Smooth potentiometer allows adjustment from $1\%$ to $100\%$ and turns off power completely when turned fully counter-clockwise.

• Automatic Standby Protection: High-level default design keeps the output disconnected until activated, protecting downstream loads from sudden power surges.

• Solderless Screw Block Terminals: 4-position terminal block provides quick, secure, solder-free power and load wiring.

IMPORTANT OPERATING NOTES:

1. DC Input Only: Strictly designed for DC voltage input sources. Never connect directly to $110\text{V}$ or $230\text{V}$ AC mains power.

2. Continuous Load Limits: While rated up to $90\text{W}$, ensure adequate airflow or additional heat sinking if running continuously near the $5\text{A}$ current limit.

Applications

• DC Motor Speed Regulation: Smooth speed tuning for brushed DC motors in power tools, robotics, and small conveyor systems.

• LED Strip Brightness Control: High-frequency flicker-free dimming for $12\text{V}$ and $24\text{V}$ single-color LED strips and panel lights.

• Fan & Blower Control: Speed control for high-current $12\text{V}/24\text{V}$ automotive or industrial enclosure cooling fans.

• Heating Element Power Tuning: Output power regulation for low-voltage DC heating pads and wire heaters.
