3 Channel PWM, Frequency, Duty Module


16 People watching this product now!




3-way PWM output, wide frequency range, duty cycle can be adjusted independently and in real time.
Frequency is divided into four ranges, automatic switching:
#The smallest unit is 1Hz, the range of values is 1Hz ~ 999Hz;
#The duty cycle ranges from 0% to 100%, of which 100% is represented by %.
#All setting parameters,
#power down save.


1. 3-way PWM output, frequency adjustable, 3-way frequency output consistent, duty cycle can be independently adjusted, suitable for most occasions;
2. LCD LCD display frequency and duty cycle, very clear, easy to adjust.
3. Wide frequency range and high accuracy;

4. Serial Communication

Used as a square wave signal generator to generate square wave signals for experimental development and use;
Square wave signal used to control motor driver;
Generate adjustable pulses for MCU use.

Generate adjustable pulses and control related circuits (PWM dimming and speed regulating applications).

The module has 8 independent keys to set the frequency and duty cycle. It supports short press (increase or decrease a unit) and long press (increase or decrease quickly). It is very simple. After setting parameters, it can save automatically without losing power.
3-way duty cycle button can be pressed at the same time, real-time adjustment, LCD display is the last pressed button duty cycle, real-time performance is very strong, can be used as a simple scan of several ways duty cycle.
