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
1、 Module description
PWM output, frequency and duty cycle can be set respectively;
Normal mode:
Frequency range: 1Hz to 150kHz duty cycle: 000 to 100, duty cycle step by step: 1
Fine mode:
Frequency range: 1Hz to 15KHz duty cycle: 00.0 to 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 to 999hz;
2. The minimum unit of x.xx (decimal point is in the hundreds) is 0.01khz, and the value range is 1.00khz to 9.99khz;
3. XX. X (decimal place is ten): the minimum unit is 0.1khz; the value range is 10.0khz to 99.9khz
4. X.x.x (decimal point in tens and hundreds): the minimum unit is 1kHz; the value range is 1kHz to 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 to 100;
All setting parameters, power down and save.
Packing: 1Pc
