Application Fields
Remote-controlled electric vehicles, self-balancing scooters, remote-controlled wheelchairs, medical robots, recreational vehicles, robotics, etc.
Application Guidelines
1. Confirm the motor's voltage and power parameters. Do not exceed the specifications of the driver board.
2. The driver board is compatible with Hall-type three-phase brushless DC motors, but not all such motors can be used directly. Ensure the motor's Hall sensor angle is 120 degrees.
3. The JYQD_YL01D braking function is regenerative braking. Rotating motors during braking generate recoverable energy. Do not test the braking function with a regulated power supply, as this may cause damage.
4. The 5V output port on the driver board can provide <100mA current for microcontroller control.
5. Ensure proper insulation and heat dissipation for power components on the driver board during operation.
6. Safety startup function: After power-on, speed adjustment will be disabled until reset. To resolve, perform either a speed reset or brake reset.

Wiring Diagram
I. Control Port (Right Side) | 2.54mm Pitch
1. 5V – Internal 5V output from control board.
2. EL – Brake control port with reactive linear braking and energy recovery. Analog voltage braking range 0-5V: Higher voltage under constant RPM increases braking force (0-100% linear scaling).
3. M – RPM signal output port. Pulse frequency proportional to motor speed (pulse ratio varies by motor model).
4. Z/F – Forward/reverse control port. Hard commutation logic:
- Connect to 5V or leave floating → clockwise rotation
- Connect to GND → counterclockwise rotation
5. VR – Speed control port. Analog voltage regulation:
- 0-5V (effective range 0-2.5V) for linear speed scaling (low to high)
- Requires common ground with driver board for external PWM input
6. GND – Control board internal ground.
II. Power Port (Left Side) | 3.96mm Pitch
1. P+ – DC power input positive (12V-48V, supports lithium batteries)
2. P- – DC power input negative
3. MC/W – Motor phase wire W
4. MB/V – Motor phase wire V
5. MA/U – Motor phase wire U
6. GND – Hall sensor ground
7. HA/HB/HC – Hall sensor signal outputs
8. 5V – Hall sensor power supply
III. Critical Notes
1. Cable Length – Motor wires should not too long to prevent signal interference.
2. Thermal Management – For continuous high-current operation : When working with continuous high current, attention should be paid to heat dissipation
IV. Safety Compliance
- Do not reverse-polarity connect P+/P-
- Verify insulation resistance (>10MΩ) between power and control ports
