                        PWM pulse frequency duty cycle adjustable module square wave rectangular wave signal generator

                        Module Highlights:

                        1.LCD display frequency and duty cycle, very clear, PWM output can be set to the frequency and duty cycle;
                        2. Wide frequency range, high precision;
                        3. Serial communication, TTL level
                        First, the module description
                        PWM output, you can set the frequency, duty cycle;

                        Frequency is divided into four ranges, automatic switching:

                        1. XXX (no decimal point): the smallest unit is 1Hz, the value range of 1Hz ~ 999Hz;
                        2. X.XX (decimal point in the hundred) the smallest unit is 0.01Khz, the range of 1.00Khz ~ 9.99Khz;
                        3. XX.X (decimal point in ten): the smallest unit is 0.1Khz; value range of 10.0KHz ~ 99.9KHz
                        4. X.X.X (decimal point in ten and hundred): the smallest unit is 1Khz; value range 1KHz ~ 150KHz
                        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.
                        Second, the 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.

                        Third, the 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 ℃.

                        Fourth, the 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 the relevant circuit (PWM dimming speed and other applications).
                        5, serial control (single-chip TTL level communication)
                         
                        Communication standard:


                        9600 bps Data bits: 8
                        Stop bit: 1
                        Check digit: none
                        Flow control: none
                        1, set the frequency of the PWM
                        "F101": Set the frequency to 101 HZ (001 to 999)
                        "F1.05": set the frequency of 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 of 105KHZ (1.0.0 ~ 1.5.0)
                        2, set the PWM duty cycle
                        "DXXX": set the PWM duty cycle to XXX; (001 ~ 100)
                        Such as D050, set the PWM duty cycle is 50%
                        3, read the set parameters
                        Send a "read" string to read the set parameters.
                        Set successfully return: DOWN;
                        Setup failed to return: FALL.
