2-channel PWM pulse frequency duty cycle adjustable module square wave rectangular wave signal generator stepper motor drive_Various types Modules

Module Highlights

1. Two independent PWM outputs, which can be set for frequency and duty cycle respectively;

2. Wide frequency range and high accuracy;

3. Can communicate via serial port

Dimensions: 41 * 28mm Thickness: 1.6mm

Two independent PWM outputs, which can be set for frequency and duty cycle respectively;

The frequency is divided into three ranges:

1. XXX (without decimal point): The small unit is 1Hz, with a value range of 1Hz~999Hz;

2.XX. X (decimal point to ten): The small unit is 0.1Khz; Value range: 0.1KHz~99.9KHz

3. x.X.X. (all three digits have a decimal point): The small unit is 1KHz; Value range 1KHz~150KHz

e. G. Frequency display: 100 represents PWM output of 100Hz pulses;

54.1 represents PWM output of 54.1KHz pulses;

1.2.4. Representing PWM output of 124KHz pulses

Duty cycle value range: 0~100;

Three frequency ranges share one duty cycle, all set parameters are saved in case of power failure.
