- This PWM module generates the adjustable square wave signal to control the motor driver and relevant circuit; Dual channel fequency signal and duty cycle complementary output, easier to control; LCD Display: the blue LCD clearly displays frequency and duty ratio, PWM output can set frequency and duty ratio independently;
- The module has 4 independent keys for setting the frequency and duty cycle, support for short press (increase or decrease of one unit) and long press (fast increase or decrease). It is very simple, set parameters automatically save, power off is not lost.
- Working voltage: 3.3 30V; Frequency range: 1Hz 150KHz; Frequency accuracy: the accuracy in each range is about 2%;
- Signal load capacity: the output current can be about 5 30mA; Output amplitude: PWM amplitude equal to the supply voltage; Ambient temperature: -20 +70 ℃.
Module parameters:
Working voltage: 3.3 ~ 30V;
Frequency range: 1Hz ~ 150KHz;
Frequency accuracy: the accuracy in each range is about 2%;
Signal load capacity: the output current can be about 5 ~ 30mA;

1. set frequency of PWM
F101: set frequency to 101HZ (001 to 999)
F1.05: set frequency to 1.05KHZ (1.00 to 9.99)
F10.5: set frequency to 10.5KHZ (10.0 to 99.9)
F1.0.5: set frequency to 105KHZ (1.0.0 to 1.5.0)

2. set PWM duty cycle
DXXX: set PWM duty cycle to XXX: (001 to 100)
Such as D050, set PWM duty cycle is 50%

3.read the set parameters
Send a "read" string to read the set parameters.
Setup successfully return: Down;
Setup failed to return: FALL.
