Adjustable PWM Pulse Frequency 1/2/3Way Signal Generator Module Duty Cycle<br>Item Description<br>Description:<br>1 Way Signal Generator (<br>Red Blue Wave)<br>100% Brand New<br>Adjustable frequency 1-160KHz<br>Duty cycle 0-100% adjustable<br>Operating voltage: 4V~30V<br>Frequency range: 1Hz~160KHz<br>Frequency accuracy: 2%<br>Signal load capacity: output current 5~30mA<br>Output amplitude: The amplitude is equal to the working voltage.<br>PWM output, can set the frequency, duty cycle<br>The frequency is divided into four ranges, automatically switching:<br>1.XXX (no decimal point): 1Hz~999Hz, unit 1Hz<br>2.X.XX (decimal point in hundreds): Value is 1.00KHz to 9.99KHz in 0.01KHz<br>3.XX.X (decimal point in ten digits): The value is 10.0KHz~99.9KHz, the unit is 0.1KHz<br>4.X.X.X. (full decimal point): Value 100KHz~160KHz, unit 1KHz<br>E.g:<br>100 represents 100Hz<br>1.00 means 1.00KHz<br>10.0 means 10KHz<br>1.0.0. Represents 100Khz<br>Setting process:<br>1. Press the SET button. The frequency parameter flashes. Set the frequency with the UP or DOWN button.<br>2. Press the SET button. The duty cycle parameter flashes. Set the duty cycle by pressing the UP or DOWN keys.<br>3. Press the SET button to exit the setting<br>4. Long press the UP and DOWN keys to quickly increase or decrease<br>5. The data is automatically memorized and all setting parameters are saved when power is off.<br>Package Included:<br>1 x Digital PWM Pulse Frequency 1-160KHz Duty Cycle Square Wave Signal Generator<br>2 Way Signal Generator<br>Two independent PWM generators can set the frequency, duty cycle;<br>The wide frequency range, high accuracy;<br>Can serial communication.<br>First, the module description:<br>Frequency is divided into three ranges:<br>XXX (no decimal point): the smallest unit is 1Hz, the range 1Hz ~ 999Hz;<br>XX.X (decimal point in ten): The minimum unit is 0.1Khz; the range of 0.1KHz ~ 99.9KHz<br>X.X.X. (there are three decimal point): the smallest unit is 1Khz; the range 1KHz ~ 150KHz<br>Frequency display example:<br>"100" indicates that the PWM output pulse of 100Hz;<br>"54.1" indicates that the PWM output pulse of 54.1KHz;<br>"1.2.4." Indicates that the PWM pulse output 124KHz<br>Duty Cycle in the range: 0 to 100;<br>Three frequencies duty cycle is the same, all the parameters non-volatile.<br>Second, the module parameters:<br>Working voltage: 5--30V, support micro USB 5.0V power supply;<br>Frequency range: 1Hz ~ 150KHz;<br>The frequency accuracy: ± 2%;<br>Output Current: <30mA;<br>Output amplitude: Default 5Vp-p (settable);<br>Operating temperature range: -30 ~ + 70 ℃.<br>Third, the parameter settings:<br>Module has three buttons [Set], [Up], [Down];<br>Press [Set] key to switch the display four parameters (FR1: PWM1 frequency; dU1: PWM1 duty cycle; FR2: frequency of PWM2; dU2: PWM2 duty cycle), before the handover parameters, there will be corresponding parameter name flash.<br>Press [Up], [Down] keys to modify the current parameter value (long press can quickly add or subtract fast).<br>Two PWM each have three preset frequency, the frequency display interface, long press [SET] key to switch between three types of frequencies, three kinds of frequency duty cycle is the same value. (XXX: range 1Hz ~ 999Hz; XX.X: range 0.1Khz ~ 99.9Khz; X.X.X .: range 1Khz ~ 150Khz,).<br>Fourth, the scope:<br>As square wave signal generator which generates a square wave signal;<br>to provide a signal to the stepping motor driver;<br>Adjustable pulse generation for chip use;<br>produce variable pulse signal, the control-related circuit (PWM dimming, speed).<br>Fifth, the serial control<br>Baud rate: 9600 bps<br>Data bits: 8<br>Stop bits: 1<br>Parity bit: none<br>Flow control: none<br>1, set the PWM frequency<br>"S1FXXXT": setting PWM1 frequency of XXX HZ (001 ~ 999)<br>"S1FXX.XT": set the frequency of PWM1 XX.X KHZ (00.1 ~ 99.9)<br>&a
