PWM Pulse Frequency Duty Cycle Adjustable Module Square Wave Square Wave Signal Generator XY-LPWMItem NO.: XY-LPWM1

XY-LPWM Signal Generator

Module Highlights:

1. LCD display frequency and duty cycle, very clear, PWM output adjustable frequency and duty cycle;

2. Wide frequency range and high accuracy;

3. Serial communication, TTL level

Module Description:

● PWM output, frequency and duty cycle can be set;

● The frequency is divided into four regions and automatically switches:

1. XXX (without comma): The minimum unit is 1Hz, and the value range is 1Hz~999Hz;

2. The minimum unit of X.XX (hundred place comma) is 0.01 Khz, ranging from 1.00 Khz to 9.99 Khz;

3. X XX (ten midpoints): The minimum unit is 0.1 Khz; Value range: 10.0 KHz~99.9 KHz

4. XXX (Decimal separator of ten and hundred): the minimum unit is 1 Khz; Value range: 1KHz~150KHz

● Frequency display: 100 represents PWM output of 100Hz pulses;

1.01 Display PWM output 1.01 K pulse;

54.1 indicates that the PWM output has a pulse of 54.1kHz;

1.2.4 indicates that the PWM output is a 124kHz pulse;

● Duty cycle range: 0-100%;

● All set parameters are automatically saved when powered off.

Parameter Settings:

The module has four independent buttons for setting frequency and duty cycle. It supports touch (increase or decrease by one unit) and long press (quick increase or decrease), and the set parameters are automatically saved without loss upon power failure

Module Parameters:

1. Working voltage: 3.3-30V;

2. Frequency range: 1Hz~150KHz;

3. Frequency accuracy: Each range accuracy is above 2%;

4. Signal load capacity: The output current can be around 5-30ma;

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

6. Environmental temperature: -20~+70 ℃.

Applicable Scope:

1. As a square wave signal generator, generate square wave signals for experimental development and use;

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

3. Generate adjustable pulses for MCU use;

4. Generate adjustable pulses and control related circuits (for purposes such as PWM dimming speed).

5. Serial port control (microcontroller TTL level communication)
