Wiring Diagram:
5V -----Driver board internal output voltage
M ---- 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:3.96 mm
5. Pay attention to the insulation between the driver MOSFET and
the heatsink or the installation plate.

Precautions
♦When using this motor drive module to adjust the speed, the motor
will have excessive current at high speed, the speed will be
unstable, and the efficiency will be reduced.
When using this motor drive module to adjust the speed, the motor
reverses at the start, the current is large, and the motor starts
to shake.
The above situation proves that the matching degree between the
motor and the drive module is low. Please ask the customer service
to adjust the data. You can replace the hardware resistor and
capacitor to achieve the best driving effect.
♦ If you use less than 60W, you don't need to add heat sink. If you
use more than 60W, you must add heat sink without heat dissipation.
The driving efficiency of the chip is reduced. If the temperature
is too high, it will cause permanent damage! The area of the heat
sink depends on the working environment (recommended heat
dissipation surface area is more than 200 square centimeters)! When
installing the heat sink, be sure to pay attention to the
insulation problem. If it is not insulated, it will cause The drive
board is permanently damaged!
♦ The power supply can't be reversed, and the reverse will be
broken immediately! Therefore, it is necessary to make sure that
the polarity of the power supply is not connected before wiring.
Xi
♦ The phase lines of the three motors can be connected freely. If
the direction is reversed, you can reverse the two phase lines.
♦ 5V on the driver board is only used for external potentiometer
speed control. Do not connect other power equipment, otherwise it
will be damaged.
♦ This drive board is connected to the speed potentiometer 1-30K,
it is recommended to use 10K potentiometer
We can supply extra assy as connector wires and heatsink.
