<div>Welcome to our store! We hope you have a wonderful shopping experience!</div>

<ul><li>Three-channel PWM is outputted,wide frequency range and the duty can be adjusted independently 
Frequency is divided into four areas,automatic switching: 1. XXX(No decimal point): 1HZ Stepping Unit,Range:1Hz~999Hz; 2. X.(The decimal is in place):0.01KHZ Stepping Unit,Range: 1.00Khz~9.99Khz; 3. X.(The decimal is in the tens place):0.1KHZ Stepping Unit,Range: 10.0Khz~99.9Khz; 4. X.X.X(The decimal is in the ones place):1KHZ Stepping Unit,Range: 1Khz~150Khz; 
E.g. ,frequency display:100 the pulse of 100Hz ; 1.01 the pulse of 1.01KHz; 54.1 the pulse of 54.1KHz; 1.2.4 the pulse of 124Hz 
The value range of dutyfactor: 0~100%,100% is represented by A0%. 
All parameters setted up can be automatically saved in case of power cut. 
Parameter: 
Has 8 keys,used to set the frequency and duty ,support short press (increase or decrease a unit) and long press (fast increase or decrease), simple,set the parameters automatically save,power loss. 
3-Way duty button can be pressed at the same time,real-time adjustment, liquid crystal display is the last pressed button duty ,real-time is strong,can be used as a simple several road duty . 
Applications: 
1.Used as square wave signal generator to generate square wave signal for experiment development and use 
2.Used to generate a square wave signal to control the motor driver; 
3.Generating adjustable pulses for MCU use; 
4.Generate adjustable pulse, control related circuit (PWM dimming speed and other applications). 
color:Photo color 
Material:PCB + electronic components 
Package Contents: 
2 x 3 Channel PWM Pulse Generator Module 
Only the above package content, other products are not included. 
Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.</li></ul>
