DESCRIPTION:

Module highlights:

1. Dual mode, 0.1% duty cycle step by step in fine mode;

2. LCD display frequency and duty cycle are very clear, and it is very convenient to adjust by using coding potentiometer; PWM output can set frequency and duty cycle respectively;

3. With locking function to prevent misoperation;

4. Upper and lower duty cycle limits can be set; kpwm with switch can turn on and off PWM output with one key;

4. Wide frequency range and high precision;

5. Serial communication

Module description

PWM output, frequency and duty cycle can be set respectively;

Normal mode:

Frequency range: 1Hz ~ 150kHz duty cycle: 000 ~ 100%, duty cycle step by step: 1%

Fine mode:

Frequency range: 1Hz ~ 15KHz duty cycle: 00.0 ~ 100%, duty cycle step: 0.1%

The frequency is divided into four ranges, which are switched automatically:

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

2. The minimum unit of x.xx (decimal point is in the hundreds) is 0.01khz, and the value range is 1.00khz ~ 9.99khz;

3. XX. X (decimal place is ten): the minimum unit is 0.1khz; the value range is 10.0khz ~ 99.9khz

4. X.x.x (decimal point in tens and hundreds): the minimum unit is 1kHz; the value range is 1kHz ~ 150kHz

e. G. frequency display: 100 represents the pulse with PWM output of 100Hz;

1.01 is the pulse with PWM output of 1.01k;

54.1 means the PWM output 54.1khz pulse;

1.2.4 represents the PWM output 124khz pulse;

Duty cycle value range: 0 ~ 100%;

All setting parameters, power down and save.
