1. Two independent PWM outputs, the frequency and duty cycle can be set separately;

 

2. Wide frequency range and high precision;

 

3. Serial communication possible

 

Dimensions: 41*28mm Thickness: 1.6mm

 

 

Two independent PWM outputs, the frequency and duty cycle can be set separately;

 

It is divided into three frequency ranges :

 

1.  XXX ( no decimal point ) : the smallest unit is 1Hz , and the value range is 1Hz~999Hz ;

 

2.  XX.X (the decimal point is in the tens place ) : the smallest unit is 0.1Khz ; the value range is 0.1 K H z~99.9K H z

 

3.  XXX ( three digits have a decimal point ) : the smallest unit is 1Khz ; the value range is 1K H z~150K H z

 

eg  Frequency display: 100  means PWM output 100Hz pulse;

 

54.1  represents the PWM output 54.1K H Z pulse;

 

1.2.4.  Represents a PWM output 124K H Z pulse

 

Duty cycle value range: 0 ~ 100 ;

 

The three frequency ranges share a duty cycle, and all setting parameters are saved after power-off.
