1. The product delivers reliable performance and multiple functions. It can stably drive most small Hall-effect brushless DC (BLDC) motors. The board features an integrated potentiometer for speed control and supports external potentiometer speed control. 2. This is a low-power brushless DC motor driver with Hall-effect sensing. It is suitable for integration into other systems and commonly used in air pumps, water pumps, oil pumps, fans, and other small-space, low-power three-phase DC BLDC motor applications, as well as industrial control and power tools. 3. Designed for user convenience, the board uses terminal block interfaces and includes pre-wired Hall sensor leads. It incorporates an onboard speed control potentiometer. 4. It supports a wide input voltage range of 6V to 24V (maximum 28V), making it compatible with various power supply systems and enhancing operational flexibility. 5. Clear wiring instructions and adjustment guidelines are provided. The intuitive design enables straightforward installation and quick parameter adjustment.
