Frequency is divided into four ranges, automatic switching:

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

2. X.XX (decimal point in the hundred) the smallest unit is 0.01Khz, the range of 1.00Khz ~ 9.99Khz;

3. XX.X (decimal point in ten): the smallest unit is 0.1Khz; value range of 10.0KHz ~ 99.9KHz

4. X.X.X (decimal point in ten and hundred): the smallest unit is 1Khz; value range 1KHz ~ 150KHz

5. e.g. frequency display:

100 indicates PWM output 100Hz pulse;

1.01 indicates PWM output 1.01K pulse;

54.1 indicates that the PWM output has a pulse of 54.1 kHz;

1.2.4 indicates that the PWM output is 124 kHz pulse;

6. Duty cycle range: 0 ~ 100%

Parameter Settings:

The module has four independent keys, used to set the frequency and duty cycle.

Support touch (increase or decrease a unit) and long press (fast increase or decrease).

The parameters automatically save, power down Not lost.
