First, module description
3-way PWM output, wide frequency range, duty cycle can be adjusted independently in real time;
Duty cycle values range from 0 to 100%, where 100% is expressed in A%.
All setting parameters are saved after power off.
Second, the parameter settings
The module has 8 independent keys to set the frequency and duty cycle, support short press (increase or decrease a unit) and long press (fast increase or decrease), it is very simple, set parameters automatically save, power off is not Lost.
The 3-way duty-cycle button can be pressed at the same time, real-time adjustment, LCD display is the duty cycle of the last pressed button, real-time is very strong, can be used as a simple several-way duty cycle scan.
Third, the module 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¡ãC.
Fourth, the scope of application:
1. It is used as a square wave signal generator to generate square wave signals for experimental development and use;
2. Used 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 the relevant circuit (PWM dimming and other applications).
