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.

Product parameters:
1. Working voltage: 3.3~30V;
2. Frequency range: 1Hz~150KHz;
3. Frequency accuracy: The accuracy in each range is about 2%;
4. Signal load capacity: The output current can be around 5~30ma;
5. Output amplitude: PWM amplitude and supply voltage are equal;
6. Ambient temperature: -20~+70°C

Serial Port Control
Communication standards: 9600 bps data bits: 8
Stop bit: 1
Check digit: none
Flow control: none

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

Application scope:
1. It is utilized as a square wave signal generator to generate square wave signals for experimental development and use;
2. Utilized to generate a square wave signal to control the motor driver;
3. Generate adjustable pulses for use by the MCU;
4. Generate adjustable pulses, control related circuits (PWM dimming speed control, etc. applications)

Package Included:
1 x Signal Generator PWM Pulse Frequency Duty Cycle Adjustable Module LCD Display
