pin name.

Pin function:

3-6V: The positive pole of the 3-6V power supply can be used with the 9-30V port

9-30V: The positive pole of the 9-30V power supply can be used with the 3-6V port

GND: negative power supply

AIN: Voltage signal input terminal

PWMA: PIM signal output terminal, the duty cycle increases as the voltage increases

PWMB: PIM signal output terminal, the duty cycle decreases as the voltage increases

4. Instructions for use

Correctly connect the supply voltage between the 3-6V or 9-30V port and GND, it will require

The input analog voltage signal is connected to AIN, and the signal needs to share the ground with the module, so the signal

The negative pole also needs to be connected to GND, to change the input analog voltage, the corresponding PWMA and

The duty cycle of the signal output by the PWMB port also changes.
