The rated current of 12A~15A needs to be used for simple heat dissipation, and 15A~20A needs to be used for thick heat dissipation. The rated power marked on the motor generally refers to the output power. Considering the motor work loss, the rated current is calculated. When considering the motor efficiency, rated current = rated power/rated voltage/efficiency)

Installation Instructions
Drive logic
COM is the signal ground, 5VO is the 5V output, which can provide 5V power for controllers such as single-chip microcomputers; the PWM pin can be connected to an external PWM, if the button control method is used, the PWM pin should be connected with 5VO; IN1 and IN2 are the forward and reverse rotation of the two-way motor , Brake (or brake) control signal. Control logic table below. Among them, 0 is low level, 1 is high level, × is any level, and it is low level when floating.

Note: When the PWM is 100% (that is, the PWM pin is always at a high level), if you want to change the rotation direction of the motor, you should first brake for more than 0.1s and then give a reverse signal, otherwise the reverse electromotive force of the motor may cause the power supply voltage. The sudden change makes the driver chip enter the protection state and does not work; for the non-full PWM state, if you want to change the rotation direction of the motor, it is best to brake for more than 0.1s before giving the reverse signal, so as to avoid large fluctuations in the power supply voltage.
Wiring method
Wiring method of using single chip microcomputer to control motor rotation The wiring method of using a single chip microcomputer to control the rotation of the motor is shown in Figure 1.6. The power supply 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 of the motor and braking; 5VO can provide 5V power for the MCU.
Use the button to control the motor forward and reverse wiring method Use the wiring method to control the forward and reverse rotation of the motor as shown in Figure 1.7. Among them, PB1 and PB2 are two buttons. When PB1 is pressed and PB2 is not pressed, IN1 is high level, IN2 is low level, the motor is running forward; when PB2 is pressed but PB1 is not pressed, IN1 is low level, IN2 is high level, The motor is reversed; when both PB1 and PB2 are bounced, IN1 and IN2 are both low, and the motor is braked (or braked)
