5. Typical Wiring Diagram

JYQD_V9.20B BLDC Motor Driver Board withJY03B IC 9-30V 6A Sensorless Brushless DC Controller with PWM & Analog Control 0

Control Interface (SET Port)
  • GND — Internal control ground
  • VR — Speed control input
    • Analog control: 0–5V linear speed regulation
    • PWM control requires common ground
  • Z/F — Direction control
    • Connect to 5V or leave floating → one direction
    • Connect to GND → opposite direction
  • M — Speed pulse output (5V signal)
  • 5V — Internal 5V output (for potentiometer/switch only)
Power Interface
  • P+ / VCC — DC power positive
  • P- / GND — DC power negative
  • MA / U — Motor phase U
  • MB / V — Motor phase V
  • MC / W — Motor phase W

6. Advantages
  • Cost-effective solution for BLDC motor control
  • Easy to integrate into existing systems
  • High efficiency and low heat generation
  • Flexible control methods (PWM + Analog)
  • Compact size saves installation space

7. Important Notes
  • Ensure motor specifications match the driver limits
  • Not all BLDC motors are directly compatible; tuning may be required
  • Keep motor wires short to reduce interference
  • Do not use the onboard 5V output for external loads
  • Ensure proper insulation and ventilation during operation
