3. Setup & Wiring
Careful wiring is essential for proper function and safety. Ensure all connections are secure and correct before applying power.
3.1 General Wiring Diagram
Figure 3: Detailed wiring diagram showing motor phase lines (MA, MB, MC), power supply (VCC, GND), 5V output, ground, PWM signal input (P), ground for external signal (G), speed pulse output (S), and Hall sensor connections (Hc, Hb, Ha, +5V, GND).
- Motor Phase Lines: Connect MA, MB, MC terminals to the corresponding phase wires of your three-phase BLDC motor.
- Power Supply: Connect DC 6-60V power to VCC (+) and GND (-) terminals.
- Hall Sensor: Connect the motor's Hall sensor wires to the dedicated 5-pin connector: GND, Hc, Hb, Ha, +5V.
- PWM Signal Input (P): For external PWM speed control.
- Ground for External Signal (G): Connect to the ground of your external control signal.
- Speed Pulse Output (S): Reserved interface for tachometer or speed feedback.
3.2 Hall Motor Connection
Figure 4: Illustrates connecting the motor phase lines (MA, MB, MC) and the Hall sensor wires (GND, Hc, Hb, Ha, +5V) from the controller to a DC three-phase brushless motor with Hall sensors.
3.3 External Signal Speed Control Wiring
Figure 5: Shows wiring for external speed control using a potentiometer or PWM signal. Note the jumper cap position for selecting between onboard potentiometer and external control. Positive and negative brakes are high-level effective PWM control, requiring an amplitude of 5V and frequency of 1-20KHz.
- PWM Input: Connect your external PWM signal to the 'P' terminal and its ground to 'G'. The amplitude should be 5V, and frequency 1-20KHz for effective control.
- External Potentiometer: Connect the potentiometer as shown in Figure 5. The potentiometer should be adjusted to its minimum position (fully counter-clockwise) when using external PWM input.
- Jumper Cap: The jumper cap on the board allows selection between using the onboard potentiometer for speed control or an external PWM/voltage control. Remove the jumper cap for external control.

4. Operation
4.1 Speed Control
- Onboard Potentiometer: If the jumper cap is in place, use the blue speed regulating potentiometer on the board to adjust motor speed. Turn clockwise to increase speed, counter-clockwise to decrease.
- External PWM/Analog Control: If the jumper cap is removed, connect an external PWM signal (5V amplitude, 1-20KHz frequency) or a 0-5V analog voltage to the 'P' terminal for speed control. Ensure the onboard potentiometer is set to its minimum position when using external control.
4.2 Direction Control
The controller supports forward and reverse operation. Connect a switch or control signal to the 'DR' terminal for direction control. Typically, a high or low signal will determine the direction.
4.3 Brake Function
The brake function is supported. Connect a control signal to the 'BRAK' terminal. A high-level signal (2.5V-5V) activates the brake, providing strong braking force.
5. Maintenance
- Cleaning: Keep the module clean and free from dust and debris. Use a soft, dry cloth for cleaning. Avoid liquids.
- Inspection: Periodically inspect all wiring connections for looseness or damage. Ensure proper ventilation around the module to prevent overheating.
- Storage: Store the module in a dry, cool environment when not in use.
6. Troubleshooting
- Motor Not Spinning: Check power supply connections, motor phase connections, and Hall sensor wiring. Verify that the speed control input (PWM or potentiometer) is active and correctly configured.
- Erratic Motor Behavior: Ensure Hall sensor wires are correctly connected and not swapped. Check for stable power supply. Verify PWM signal quality if using external control.
- Overheating: Ensure the module is not overloaded beyond its 400W/15A capacity. Provide adequate ventilation.
- No Speed Control: If using external PWM, ensure the jumper cap is removed and the onboard potentiometer is at its minimum. Check the external PWM signal amplitude (5V) and frequency (1-20KHz).
