The DC brushless Hall driver board uses the JY01 chip as the core, with the LM339 comparator and the IR2101s gate driver IC, to provide an efficient and stable DC brushless motor drive solution. The driver board supports precise control of the Hall brushless motor. It only needs to connect the Hall signal line and the motor UVW three-phase line to control the motor rotation. Supports SPWM drive mode, speed adjustment through PWM signal, and can control the motor forward and reverse rotation through pins. The driver board has overcurrent and overtemperature protection functions to ensure safe and stable operation of the motor. Input power supply voltage: 12~37V Supports maximum output current 5A Onboard Hall sensor interface, supports Hall brushless motor Motor speed is adjusted by potentiometer Built-in protection circuit, with over-current and over-temperature protection function to ensure safe operation of the motor Support SPWM drive mode Adopt LM339 high-performance comparator to improve signal stability Instructions for use: 1. Power the driver board (DC 12-37V) 2. Connect the potentiometer and turn the potentiometer knob counterclockwise to the lowest gear to prevent the motor from automatically turning on when powered on 3. Connect the brushless motor output line (the three wires of the three-phase brushless motor can be connected in any order, and the direction of rotation of the motor can be changed by changing the connection order of any two wires) 4. Connect the motor's Hall signal lines HA, HB, HC 5. Slowly rotate the potentiometer knob clockwise and the motor will start to rotate.
