1Hz-150Khz Signal Generator PWM Board Module Pulse Frequency Duty Cycle Adjustable Module LCD Display 3.3V-30V 1Hz - 150Khz

Highlights
1 LCD display frequency and duty cycle, very clear, PWM output can be set separately frequency and duty cycle;
2. Wide frequency range, high precision;
3. It can use serial communication

Description
PWM output, you can set the frequency, duty cycle;
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
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;

Duty cycle range: 0 ~ 100%;
All set parameters, power down save.
