1Hz-150Khz Signal Generator PWM Pulse Frequency Duty Cycle Adjustable Module LCD Display 3.3V-30V PWM Board Module

Origin:CN(Origin)
Package:Yes
Model Number:1Hz-150Khz 3.3V-30V Signal Generator

WM output, wide frequency range, duty cycle adjustable independently
Frequency is divided into four ranges, automatic switching
1.XXX (no decimal point): The minimum unit is 1Hz, the value range is 1Hz~999Hz
2.X.XX (the decimal point is in the hundred places) is 0.01Khz, the value range is 1.00Khz~9.99Khz
3,XX.X (decimal point in ten): The minimum unit is 0.1Khz: Value range 10.0KHz~999KHz
4.X.X.X (decimal point is in ten and one hundred place): the minimum unit is 1Khz: the value range is 1KHz~150KHz
Frequency display:
100 indicates PWM output 100Hz pulse
101 indicates PWM output 1.01K pulse
54.1 indicates PWM output 54.1KHz pulse
1.2.4 indicates PWM output pulse of 124KHz
Duty cycle values range from 0 to 100%, where 100% is expressed in A%.
All setting parameters, save power off
Feature:
1>. LCD display frequency and duty cycle, very clear, PWM output can be set to the frequency and duty cycle;
2>. Wide frequency range, high precision;
3>. Serial communication, TTL level
Parameters:
1>. Working voltage: 3.3 ~ 30V;
2>. Frequency range: 1Hz ~ 150KHz;
3>. Frequency accuracy: the accuracy in each range is about 2%;
4>. Signal load capacity: the output current can be about 5 ~ 30ma;
5>. Output amplitude: PWM amplitude equal to the supply voltage;
6>. Ambient temperature: -20 ~ +70 °.
Application:
1>. Used as a square wave signal generator, generate square wave signal for experimental development and use;
2>. Used to generate a square wave signal that controls the motor driver;
3>. generate adjustable pulse for MCU use;
4>. generate adjustable pulse, control the relevant circuit (PWM dimming speed and other applications).
5>. serial control (single-chip TTL level communication)
Communication standard:
9600 bps Data bits: 8
Stop bit: 1
Check digit: none
Flow control: none
1>. set the frequency of the PWM
"F101": Set the frequency to 101 HZ (001 to 999)
"F1.05": set the frequency of 1.05 KHZ (1.00 ~ 9.99)
"F10.5": Set the frequency to 10.5KHZ (10.0 ~ 99.9)
"F1.0.5": set the frequency of 105KHZ (1.0.0 ~ 1.5.0)
2>. set the PWM duty cycle
"DXXX": set the PWM duty cycle to XXX; (001 ~ 100)
Such as D050, set the PWM duty cycle is 50%
3>. read the set parameters
Send a "read" string to read the set parameters.
Set successfully return: DOWN;
Setup failed to return: FALL.
