Product Description:brand new high qualityMade of high quality material,Module highlights:1. LCD display frequency and duty cycle, clear at a glance, for PWM output can set frequency and duty cycle;2. Wide frequency range and high for precision;3. Serial communication, for TTL level1. Module Description for PWM output, frequency and duty cycle can be set;The frequency is divided into four ranges with automatic switching:1. XXX(no decimal point): the minimum unit is 1Hz, and the value range is 1Hz～999Hz;2. The minimum unit of X.XX(hundreds decimal point) is 0.01Khz, and the range is 1.00Khz～9.99Khz;3. XX.X(ten decimal places): the minimum unit is 0.1Khz; the value range is 10.0KHz～99.9KHz4. X.X.X(decimal point for tens and hundreds): the minimum unit is 1Khz; the value range is 1KHz～150KHz Frequency display: 100 means for PWM output 100Hz pulse;1.01 means for PWM output 1.01K pulse;54.1 means that the for PWM output has a 54.1kHz pulse;1.2.4 means that the for PWM output is 124kHz pulse;Duty cycle range: 0~100%;All setting parameters are automatically saved when power off.2. Parameter settingThe module has four indep endent buttons for setting the frequency and duty cycle. It supports touch(increase or decrease by o ne unit) and long press( increase or decrease). The parameters are automatically saved and will not be lost when power is off.3. Module parameters:1. Working voltage: 3.3~30V;2. Frequency range: 1Hz～150KHz;3. Frequency accuracy: the accuracy of each range is about 2%;4. Signal carrying capacity: the output current can be around 5-30ma;5. Output amplitude: for PWM amplitude is equal to the power supply voltage;6. Ambient temperature:-20～+70℃.4. Scope of application:1. Used as a square wave signal generator to generate square wave signals for experimental development;2. Used to generate a square wave signal to control the motor driver;3. Generate adjustable pulses for MCU use;4. Generate adjustable pulses and control related circuits( for PWM dimming speed and other applications).5. Serial port control(SCM for TTL level communication)Communication standard:9600 bps Data bits: 8stop bits: 1Check digit: none Control: None1. Set the frequency of for PWM"F101": Set the frequency to 101 HZ(001 to 999)"F1.05": set frequency 1.05KHZ(1.00～9.99)"F10.5": Set the frequency to 10.5KHZ(10.0～99.9)"F1.0.5": Set the frequency to 105KHZ(1.0.0～1.5.0)2. Set the for PWM duty cycle"DXXX": set the for PWM duty cycle to XXX;(001~ 100)Such as D050, set the for PWM duty cycle to 50%3. Read setting parametersSend a"read" string to read the set parameters.Set successfully return: DOWN;Installation failure returns: FALLPackage Included:1* moduleNote:1.The real color of the item may be slightly different from the pictures shown on website caused by many factors such as brightness of your monitor and light brightness.2.Please allow slight manual measurement deviation for the data.
