5V–12V Brushless DC Motor Driver Controller Board | 3/4 Wire

5V–12V Brushless DC Motor Driver Controller Board

Take full control of your brushless DC motors with this compact, reliable driver controller board. Designed to drive sensorless (hall-free) 3-wire and 4-wire brushless motors — including hard disk drive (HDD) motors, CD-ROM spindle motors, and similar micro brushless motors — this board packs essential protection features into a small, easy-to-integrate package. Made in Mainland China.

Key Features

• Wide Voltage Range: Operates on DC 5V to 12V, making it compatible with a broad range of power supplies and project setups.
• Reverse Voltage Protection: Safeguards your board and motor from accidental reverse polarity connections.
• Over-Current Protection: Automatically limits current draw (≤1.2A working current) to protect the driver chip and connected motor.
• Phase Inversion Control: Easily reverse motor spin direction via phase inversion, giving you flexible directional control.
• Full Speed Adjustment: Smooth speed control from 0% to 100% — ideal for variable-speed applications.
• Compatible with Sensorless (Hall-Free) Motors: Drives brushless motors without hall-effect sensors, expanding compatibility with common salvaged and OEM motors.
• Compact Form Factor: Measures just 6 × 4.5 cm (approx. 2.36″ × 1.77″) — easy to fit into tight enclosures or DIY builds.

Usage Notes

• Ensure all brushless motor wires are firmly secured in the terminal block. Loose connections can cause phase loss, erratic operation, or damage to the driver chip.
• Use appropriately gauged wire for board terminal connections — thicker wire is recommended due to the screw terminal clearance design.
• Identifying the COM terminal on a 4-wire motor: Use a multimeter in resistance mode. Test all four terminals. The terminal that shows the lowest and equal resistance to each of the other three terminals is the COM (common) terminal.
• Colors shown in product images may vary slightly depending on your monitor calibration.

Package Includes

• 1 × 5V–12V Brushless DC Motor Driver Controller Board

Frequently Asked Questions

Q: What types of brushless motors is this driver controller board compatible with?

A: This brushless DC motor driver board is designed for sensorless (hall-free) 3-wire and 4-wire brushless DC motors, such as hard disk drive (HDD) spindle motors and CD-ROM brushless motors. It is not intended for motors that require hall-effect sensor feedback.

Q: What voltage and current does this motor driver board support?

A: The board supports a driver voltage of DC 5V to 12V and operates at a working current of ≤1.2A. It includes built-in over-current protection to help prevent damage to the chip and connected motor.

Q: How do I identify the COM terminal on a 4-wire brushless motor?

A: Use a multimeter set to resistance mode. Test each of the four terminals against the other three. The terminal that reads the lowest — and equal — resistance to all three remaining terminals is the COM (common) terminal. Correctly identifying this terminal before connecting to the driver board is important for proper operation.

Q: Can I control the motor speed with this driver board?

A: Yes. This driver controller board supports full variable speed adjustment from 0% to 100%, allowing precise speed control for your brushless motor application.

Q: Does this board offer any protection features?

A: Yes. The board includes reverse voltage protection (guards against accidental polarity reversal), over-current protection (limits current to protect the driver chip), and phase inversion control for directional flexibility.
