5V 12V Brushless Motor Driver Board with Adjustable Speed Control for HDD CDROM 3‑Wire 4‑Wire Motors

Compact 5V to 12V brushless motor driver board for HDD and CDROM motors Key benefits Drives small brushless motors taken from hard disk drives and CDROM drives, supporting micro 3wire and 4wire brushless motors without Hall sensors. Adjustable speed from 0 percent to 100 percent for precise control of motor rpm. Builtin protections reduce risk of damage during use: reverse voltage protection, over current protection, and phase inversion control. Small, lightweight and easy to integrate into DIY electronics, robotics, laboratory setups, and motor repurposing projects. Features and specifications Material: plastic and electrical components Color: green and black Driver voltage: DC 5 to 12 V Working voltage: <=1.2A Speed adjustment range: 0 percent to 100 percent Protections: reverse voltage protection, over current protection, phase inversion control Compatible motor types: hard disk brushless motors, CDROM brushless motors, and other small 3wire or 4wire brushless motors without Hall sensors Size: 6.0 x 4.5 cm (2.36 x 1.77 inches) Quantity: 1 piece Package includes: 1 piece 5V12V DC brushless motor driver board controller Installation and usage notes Ensure motor wires are pressed firmly into the receiving terminals on the driver board. Poor contact can cause loss of phase operation and may burn out the chip. Terminal screws have some clearance. Use thicker, solid conductors where possible to ensure reliable connection. Identifying the common port on a fourwire motor: measure resistance between terminals with a multimeter. The COM terminal is the one whose resistance to each of the other three terminals is the lowest and approximately equal. Practical applications DIY projects: repurpose HDD or CDROM motors for custom turntables, spindles, or motorized displays where compact, adjustable speed control is required. Robotics and automation: power small brushless motors in experimental robots, actuators, or prototype devices that require variable speed and simple control. Electronics education and testing: use the board for motor control experiments, electronics labs, and hobbyist testing of brushless motor behavior without Hall sensors. Important reminder Follow wiring and terminal seating guidance to avoid poor contacts and potential damage to the driver board. Color of the actual item may vary slightly from images due to monitor differences.
