The JYQD_V9.20B Brushless DC Motor Driver Board is a compact and efficient solution designed for driving three-phase sensorless BLDC motors. With a wide input voltage range of 9V to 30V and support for both PWM and analog speed control, this driver ensures stable and precise motor performance.

Engineered for reliability and ease of integration, it is ideal for a wide range of applications including fans, pumps, and smart automation systems.

• Wide operating voltage: 9V – 30V DC
• Peak current up to 6A, continuous 3A
• Supports PWM speed control (1–20kHz)
• Supports 0–5V analog voltage control
• Built-in speed pulse signal output
• Forward and reverse rotation control
• Compact design for easy installation
• Stable performance for motors under 100W

The JYQD_V9.20B BLDC motor driver is widely used in:

• Water pumps
• Cooling fans
• Air circulation systems
• Smart home devices
• Industrial automation equipment
• Small electric machinery

• 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)

• 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

• 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

• 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
