## Overview

The HiLetgo 2pcs 3 Channel PWM Pulse Generator is a versatile signal generator module that allows for adjustable frequency and duty cycle settings across three channels. With a wide frequency range of 1Hz to 150KHz and an intuitive LCD display, this module is designed for ease of use and real-time adjustments, making it ideal for both hobbyists and professionals in electronics.

## Description

Description:  Three-channel PWM is outputted,wide frequency range and the duty ratio 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.XX(The decimal is in the hundreds place):0.01KHZ Stepping Unit,Range: 1.00Khz~9.99Khz; 3.X.XX(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 represent the pulse of 100Hz ; 1.01 represent the pulse of 1.01KHz;  54.1 represent the pulse of 54.1KHz 1.2.4 represent 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 independent keys,used to set the frequency and duty ratio,support short press (increase or decrease a unit) and long press (fast increase or decrease),very simple,set the parameters automatically save,power loss. 3-Way duty ratio button can be pressed at the same time,real-time adjustment, liquid crystal display is the last pressed button duty ratio,real-time is very strong,can be used as a simple several road duty ratio scan. 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). Package included:  2* 3 Channel PWM Pulse Generator Module Adjustable Frequency

### ⭐⭐⭐⭐⭐ Here's How you can program these with Serial commands
*by M***A on January 23, 2025*

The media could not be loaded. I use this PWM generator with the Drok 160W dual motor H-bridge. Yes, if you want to program it with the Arduino or another SBC, you will have to hunt around for the code. Here is how I program my Arduino Due in my HB Sat tracking unit. // Freq and the duty cycle are set for Azmuith and Elevation. Note the code below sets up the module for 5,000 Hz at 30% on both motors. My 10rpm worm drive motors operate very smoothly. See my video. The working code below. Put this in your setup area in the sketchSerial3.begin(9600); // Due board D14 & D15 tx/rx to rx/tx on pwm multiple channel generatorSerial3.write("F05.00");delay(100);Serial3.write("D1:030");delay(100);Serial3.write("D2:030");delay(100);Have fun!MikeKD0ZW.com

### ⭐⭐⭐⭐⭐ Quality module and works great!
*by K***R on August 19, 2024*

The media could not be loaded. Good quality module with a nice durable build. It does exactly what it is supposed to do and I didn't have any problems at all. I used this as a stand-alone module to manually dim a 5mm LED and power a 6v dc motor. You can also add a trigger (button/pir motion sensor/photoresistor...etc) to turn the module on and off. I added a momentary button to start and stop the motor.You can also use this precision module for:*Servo Motor Position Control*Pulse Width Modulation for Heating Elements*Tone Generation for Buzzersand *Light Flasher/Strobe to name a fewYou can attach a fan blade to a dc motor shaft and use it with an oscilloscope for educational purposes. Using a flan blade and motor shaft setup to view waveforms on an oscilloscope helps in understanding the conversion of mechanical motion into electrical signals, the characteristics of periodic signals, and practical applications of sensors and signal processing. It’s a hands-on method that makes abstract concepts more concrete and easier to grasp.Keep in mind:While a PWM module can dim 5mm LEDs effectively, it is not suitable for controlling WS2812B LEDs due to their need for precise digital signaling. For WS2812B, use a dedicated LED controller or a microcontroller capable of handling the required digital communication.You can use this module with basic digital servo motors but you will need to manually change duty cycle for position control. For better servo control, you might want to consider a dedicated servo controller or a PWM driver board designed specifically for servos, which can provide the necessary resolution, accuracy, and power to ensure optimal performance.

### ⭐⭐⭐⭐⭐ Convenient
*by M***T on September 3, 2024*

Works well. Not sure how accurate it is but I have full adjustability for what I need.
