Signal Generator PWM Pulse Frequency Duty Cycle Adjustable Module LCD Display 1Hz-150Khz 3.3V-30V
1. Description:

PWM output, you can set the frequency, duty cycle;

Frequency is divided into four ranges, automatic switching:

    XXX (no decimal point): the smallest unit is 1Hz, the value range of 1Hz ~ 999Hz;

    X.XX (decimal point in the hundred) the smallest unit is 0.01Khz, the range of 1.00Khz ~ 9.99Khz;

    XX.X (decimal point in ten): the smallest unit is 0.1Khz; value range of 10.0KHz ~ 99.9KHz

    X.X.X (decimal point in ten and hundred): the smallest unit is 1Khz; value range 1KHz ~ 150KHz

    e.g. frequency display:

    100 indicates PWM output 100Hz pulse; 1.01 indicates PWM output 1.01K pulse; 54.1 indicates that the PWM output has a pulse of 54.1 kHz; 1.2.4 indicates that the PWM output is 124 kHz pulse;

    Duty cycle range: 0 ~ 100%;

    All set parameters, power-down automatically saved.

2. Feature:

    LCD display frequency and duty cycle, very clear, PWM output can be set to the frequency and duty cycle;

    Wide frequency range, high precision;

    Serial communication, TTL level

3. Parameter Settings:

The module has four independent keys, used to set the frequency and duty cycle, support touch (increase or decrease a unit) and long press (fast increase or decrease), set the parameters automatically save, power down Not lost.
4. Parameters:

    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 about 5 ~ 30ma;
    Output amplitude: PWM amplitude equal to the supply voltage;
    Ambient temperature: -20 ~ +70 ℃.

5. Application:

    Used as a square wave signal generator, generate square wave signal for experimental development and use;

    Used to generate a square wave signal that controls the motor driver;
    generate adjustable pulse for MCU use;
    generate adjustable pulse, control the relevant circuit (PWM dimming speed and other applications).
    serial control (single-chip TTL level communication)

6. Communication Standard:

    9600 bps Data bits: 8
    Stop bit: 1
    Check digit: none
    Flow control: none
