X2pcs 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%;
• 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   cycle

• DXXX: set PWM   cycle to XXX: (001 to 100)
• Such as D050, set PWM   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.
