PWM Pulse Frequency Duty Cycle Square Wave GL Signal Generator Module E70

Module Highlights:
LCD display frequency and duty cycle, very clear, PWM output can be set to the frequency and duty cycle;
Wide frequency range, high precision;
Serial communication, TTL level
 
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
 
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 automatically saved.
 
Parameter setting: 
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), set the parameters automatically save, power down Not lost.
