PWM Pulse Frequency Duty Cycle Adjustable Module XY-LPWM Squarre Wave Rectangular Wave Signal Generator

PWM Pulse Frequency Duty Cycle Adjustable Module XY-LPWM Squarre Wave Rectangular Wave Signal Generator
Description:
Output, frequency and duty cycle can be set separately;
Frequency is divided into four ranges, 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 (the decimal point is in the hundreds place) is 0.01Khz, and the value range is 1.00Khz~9.99Khz;
(decimal point in tens):the minimum unit is 0.1Khz; value 10.0KHz~99.9KHz (decimal point in tens and hundreds):minimum unit is 1Khz; value 1KHz~150KHz
e.g. Frequency display:100 means PWM output 100Hz pulse;
1.01 means PWM output 1.01K pulse; 54.1 means PWM output 54.1KHz pulse;
1.2.4 means PWM output 124KHz pulse;
Duty cycle value range:0~100%;
All setting parameters are saved after power off.
Specifications:
Working voltage:3.3~30V
Frequency range:1HZ~150KHZ; Frequency accuracy:the accuracy in each range is about 2%
Signal load capacity:the output current can be around 5~30MA
Output amplitude:PWM amplitude is equal to the supply voltage
Ambient temperature:-20~+70?}
Features:
1. LCD liquid crystal display frequency and duty cycle, very clear, PWM output can
Set frequency and duty cycle separately;
2. Wide frequency range and high precision
3. Serial port communication
Package Include:
1??PWM Pulse Frequency Duty Cycle Adjustable Module
Parameter Settings:
The module has 4 independent buttons, which are used to set the frequency and duty cycle. It supports short press (increase or decrease by one unit) and long press (increase or decrease quickly). Very simple, the parameters are automatically saved after setting, and will not be lost when power off.
Serial port control:
Communication standard:9600 BPS Data bits:8
stop bit:1
Check digit:NONE
Flow Control:NONE
1. Set the frequency of PWM
‘F101’:Set the frequency to 101HZ (001~999)
‘F1.05’:Set the frequency to 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 to 105KHZ (1.0.0~1.5.0)
2. Set the duty cycle of PWM
‘DXXX’:set the duty cycle of PWM to XXX; (001~100)
For example, D050, set the PWM duty cycle to 50%
3. Read setting parameters
Send ‘READ’ string to read the set parameters.
Set successfully return:DOWN;
If the setting fails, return:FALL.
