Attention:
The rated power marked on a motor generally refers to the output power, considering the work loss of the motor, so the motor efficiency should be considered when calculating the rated current, rated current=rated power/rated voltage/efficiency.


Use a switching power supply chip to provide 5V for the internal circuit of the module, with low heat generation and high efficiency. It supports a wider voltage range; use a half-bridge chip to drive high-power MOS tubes, which are high-rate and reliable.

Note: It is recommended to connect a 20A fuse in series at the power supply.


Using imported high-power MOS tube with 110A peak current. Its driving ability is very strong to drive motor.

Drive Logic:
COM is the signal ground, and 5VO is the 5V output, which can provide 5V power supply for MCUs and other controllers. The PWM pin can be connected with PWM. If the button control mode is used, the PWM pin should be connected with 5VO. IN1 and IN2 are two-way motor forward and reverse, brake (or brake) control signals. The control logic is as follows. Among them, 0 is low level, 1 is high level, X is any level, and it is low level when floating.


Attention:
- When switching between forward and reverse, it is best to brake for more than 0.1S and then reverse, otherwise the driver may be damaged. When PWM is 100%, if you want to switch the motor direction, you must brake for more than 0.1S before giving the reverse signal.
- It is recommended to connect a 20A fuse in series at the power supply.

Electrical Parameters:
- Motor power supply input voltage: DC6.5V～40.0V (please connect the positive and negative poles of power supply correctly. The voltage should not exceed 40V, otherwise it may burn the device)
- Maximum load current: 12A (no heat dissipation); 15A (simple heat dissipation); 20A (thick large heat sink) (simple heat dissipation: for example, put a 1mm thermal silica pad under the module and then use a 5mm copper pillar to fix the module to the device wall .Please make the heat dissipation treatment by yourself according to the current situation)
- Output power: 12V 180W; 24V 360W; 36V 540W (assuming simple heat dissipation, the maximum long-term load current is 15A)

The size of the drive module is 5.5x5.5cm/2.2x2.2", and the height is 2.0cm/0.8". The diameter of the mounting hole is 3mm/0.12", and it is recommended to use M3 screws for fixing. Please be careful not to short-circuit the back components during installation. It is recommended to use a 1mm/0.04" thick thermally conductive silicone pad on the back of the module, and then use a 5mm/0.2" high copper pillar to fix the module.


Wiring Methods:
1. Use MCU to Control Motor Rotation
The wiring method of using MCU to control motor rotation is shown in the figure. The power supply ground of the MCU is connected to the COM of the drive module; the PWM pin is connected to the PWM output of the MCU for speed regulation; IN1 and IN2 are connected to the two IOs of the MCU to control the forward and reverse rotation and braking of the motor; 5VO can provide 5V power supply for the MCU.


2. Use Buttons to Control the Motor Forward and Reverse
Use the wiring method to control the forward and reverse rotation of the motor as shown in the figure. Among them, PB1 and PB2 are two buttons. When PB1 is pressed but PB2 is not pressed, IN1 is high, IN2 is low, and the motor rotates forward; when PB2 is pressed but PB1 is not pressed, IN1 is low and IN2 is high, the motor reverses; when both PB1 and PB2 bounce up, IN1 and IN2 are both low, and the motor brakes (or brake).
