PWM Controller Pulse Frequency Duty Ratio Adjustable Module Square Wave Rectangular Wave Signal Generator

Product Description
Module features:The display frequency and duty ratio of LCD with enclosure are very clear. PWM output can set the frequency and duty ratio respectively;Wide frequency range and high accuracy;Serial communication
I. module description
PWM output, the frequency and duty cycle can be set respectively;
Frequency is divided into four ranges, automatic switching: XXX(no decimal point) : the minimum unit is 1Hz, and the value range is 1Hz~999Hz; The minimum unit of X.XX (decimal point in the hundreds place) is 0.01Khz, with a value range of 1.00Khz~9.99Khz;XX.X(the decimal point is in the tens place) : the smallest unit is 0.1khz;Value range is 10.0KHz~99.9KHzX.X.X (decimal in tens and hundreds) : the smallest unit is 1Khz;Values range from 1KHz to 150KHz
Frequency display: 100 represents PWM output pulse of 100Hz;1.01 means the PWM output pulse of 1.01K;54.1 denotes PWM output pulse of 54.1KHz;1.2.4 indicates PWM output pulse of 124KHz;
Range of duty cycle: 0~100%;
Set all parameters, power down and save.
Input PWM amplitude = input voltage
2. Parameter Setting
The module has 4 independent buttons to set frequency and duty ratio. It supports short press (increase or decrease one unit) and long press (rapid increase or decrease). It is very simple.
3. ParameterWorking voltage: 3.3~30V;Frequency range: 1Hz~150KHz;Frequency accuracy: about 2% in each range;Signal load capacity: output current can be around 5~30ma;Output amplitude: PWM amplitude is equal to the supply voltage;The environment temperature: - 20 ~ + 70 ℃.
4. ApplicationUsed as square wave signal generator to generate square wave signals for experimental development and use;Square wave signal used to control the motor driver;Generate adjustable pulse for MCU use;Generate adjustable pulse and control related circuits (PWM dimming and speed regulation, etc.).
5. Serial Control
Communication standard :9600 BPS data bit :8
Stop bits: 1.
Check digit: none
Flow control: none
1. Set the frequency of PWM
"F101" : set frequency to 101 HZ (001~999)
"F1.05" : set frequency as 1.05 KHZ (1.00~9.99)
"F10.5" : set frequency to 10.5KHZ (10.0~99.9)
"F1.0.5" : set frequency to 105KHZ (1.0.0~1.5.0)
2. Set the duty cycle of PWM
"DXXX" : set the duty cycle of PWM to be XXX;(001 ~ 100)
For example D050, set the PWM duty ratio to be 50%
3. Read the setting parameters
Send the "read" string and read the parameters set.
Set successful return: DOWN;
Set failed return: FALL.
