PWM Pulse Frequency Duty Cycle Adjustable Module Square Rectangular Wave Signal Generator

Module highlights:

1. LCD liquid crystal display with case for frequency and duty cycle, very clear, PWM output can be set separately for frequency and duty cycle;

2. Wide frequency range, high precision;

3. Serial communication

I. Module Description

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

Frequency is divided into four ranges, automatic switching:

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

2. X.XX (decimal point in hundredths): the smallest unit is 0.01Khz, value range 1.00Khz~9.99Khz;

3. XX.X (decimal point in tens place): the smallest unit is 0.1Khz; value range 10.0Khz~99.9Khz

4. X.X.X (decimal point in tenth and hundredth place): the smallest unit is 1Khz; the value range is 1KHz~150KHz.

e.g. Frequency Display: 100 means PWM outputs 100Hz pulse;

1.01 means PWM outputs 1.01K pulse;

54.1 means PWM outputs 54.1KHz pulse;

1.2.4 means PWM outputs 124KHz pulse;

Duty cycle value range: 0~100%;

Parameter setting

The module has 4 independent buttons to set the frequency and duty cycle, support short press (increase or decrease a unit) and long press (fast increase or decrease), very simple, the parameters are automatically saved after setting, power down is not lost.

Third, the module parameters:

1. Operating voltage: 3.3~30V;

2. Frequency range: 1Hz~150KHz;

3. Frequency accuracy: the accuracy on each range is about 2%;

4. Signal loading capacity: output current can be around 5~30ma;

5. Output amplitude: PWM amplitude is equal to the supply voltage;

6. Ambient temperature: -20~+70℃.

IV.Scope of application:

1. Used as a square wave signal generator to produce square wave signals for experimental development;

2. Used to generate square wave signals for controlling motor drivers;

3. Generate adjustable pulses for MCU use;

4. Generate adjustable pulses to control related circuits (PWM dimming and speed control and other applications).

V. Serial port control (microcontroller TTL level communication)

1、 Set the frequency of PWM

"F101": set frequency to 101 HZ (001~999)

"F1.05": set frequency to 1.05 KHZ (1.00~9.99)

"F10.5":Set frequency to 10.5 KHZ (10.0~99.9)

"F1.0.5":Set frequency to 105KHZ (1.0.0~1.5.0)

2、 Set the duty cycle of PWM

"DXXX":Set the duty cycle of PWM to XXX; (001~100)

For example, D050, set PWM duty cycle is 50%.

3、 Read the setting parameters

Send "read" string to read the set parameters.

Setting success returns: DOWN;

Setting failure returns: FALL.
