  • Features analog voltage speed regulation (0-5V) for linear speed control.
  • Includes speed pulse signal output for monitoring motor performance.
  • Equipped with over-voltage and under-voltage protection for enhanced safety.
  • Designed for sensorless three-phase brushless DC motors, ensuring compatibility with a wide range of motors.
  • Compact and lightweight bare PCB design, ideal for motors below 36W without forced cooling.
  • Control and power ports use a 2.54 mm pitch for easy connectivity and integration.
Faqs:
  • What is the operating voltage range of the JYQD-V8.20B BLDC Motor Driver Board?
    The JYQD-V8.20B operates within a voltage range of 5V to 28V, making it versatile for various brushless motor applications.
  • Can the JYQD-V8.20B be used with any brushless motor?
    The driver is designed for sensorless three-phase brushless DC motors, but not all motors are compatible. Users may need to fine-tune resistors or capacitors for optimal performance if issues like startup jitter or reverse rotation occur.
  • Does the JYQD-V8.20B require forced cooling?
    For motors below 36W, no forced cooling is required, but proper ventilation must be ensured to maintain optimal performance.
  • What is the purpose of the 5V output terminal on the board?
    The 5V output terminal is intended only for external potentiometers or switches used for speed and direction control and must not be used to power external devices.
