For more details, please see the link picture, thank you

Highlights

1 LCD display frequency and duty cycle, very clear, PWM output can be set separately frequency and duty cycle;

2. Wide frequency range, high precision;

3. It can use serial communication

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

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 save.

Parameter settings

The module has four independent keys, used to set the frequency and duty 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)
