Description

Parameter settings:

The module has four independent keys, used to set the frequency and duty cycle, support short press (increase or decrease a unit)
and long press (fast increase or decrease), very simple, set the parameters automatically save, power failure Lost.
 
Module 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 ℃.
 
Scope of 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 related circuit (PWM dimming speed and other applications)
 
Serial Port Control:

Communication standards: 9600 bps data bits: 8
Stop bit: 1
Check digit: none
Flow control: none

1. set frequency of PWM
F101: set frequency to 101HZ (001 to 999)
F1.05: set frequency to 1.05KHZ (1.00 to 9.99)
F10.5: set frequency to 10.5KHZ (10.0 to 99.9)
F1.0.5: set frequency to 105KHZ (1.0.0 to 1.5.0)

2. set PWM duty cycle
DXXX: set PWM duty cycle to XXX: (001 to 100)
Such as D050, set PWM duty cycle is 50%

3.read the set parameters
Send a "read" string to read the set parameters.
Setup successfully return: Down;
Setup failed to return: FALL.
 
Package included:
 
5 x 1Hz-150Khz 3.3V-30V Signal Generator
