1-100PCS PWM Pulse Frequency Duty Cycle Square Wave Signal Generator Module New

1-100PCS PWM Pulse Frequency Duty Cycle Square Wave Signal Generator Module New Item Description 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.
