5pcs 1Hz-150Khz 3.3V-30V Signal Generator PWM Pulse Frequency Cycle Adjustable Module LCD Display
Parameter settings:
The module has four independent keys, used to set the frequency and 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 percent;
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 degree
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 cycle
DXXX: set PWM cycle to XXX: (001 to 100)
Such as D050, set PWM cycle is 50 percent
3.read the set parameters
Send a "read" string to read the set parameters.
Setup successfully return: Down;
Setup failed to return: FALL.
Package Contains:
5pcs x 1Hz-150KHz 3.3V-30V Signal Generator
