Max Current 3A, 12V/24V Brushless DC Motor Driver PWM Control For Sensorless BLDC Motor with connector wires

5V -----Driver board internal output voltage
SC ---- Motor speed pulse signal output port, 5V pulse signal.

1. Control port
Z/F---- Rotating direction control ports. Connect “5V” high level or no connect is Forward direction,
connect 0 V low level or connect to GND is reverse direction.
VR ----Speed control port. Analog voltage linear speed regulation 0.1v -5V, The input resistance is 20K Ohm ,connect with GND when input PWM speed regulation, PWM frequency:1-20KHZ; Duty cycle 0-100%
GND—Used for Drive board internal control

2. Power port
MA ----motor phase A
MB ---- motor phase B
MC---- motor phase C
GND----DC-

VCC----DC +

3. Use shielded wires if the drivers board has more than 50 cm distance from the motor, otherwise it
may lead to abnormal driving, affecting the normal use.

4. Control port distance: 2.54mm,Power port distance:2.54 mm

5. Pay attention to the insulation between the driver MOSFET and the heatsink or the installation plate.
