Digital Signal Generator 1HZ~150KHZ PWM Pulse Frequency Duty Cycle Adjustable module Square wave XY-LPWM

Module description

PWM output can set frequency and duty cycle respectively.

Frequency is divided into four areas: automatic switching:
1.XXX (without decimal point): the smallest unit is 1Hz, and the value range is 1Hz~999Hz;
2.X.XX (decimal point in 100 bits) is 0.01Khz, and its range is 1.00Khz~9.99Khz;
3.XX.X (decimal point in ten places): the smallest unit is 0.1Khz; and the range is 10.0KHz~99.9KHz.
4.X.X.X (decimal point in ten bits and 100 bits): the smallest unit is 1Khz; and the range is 1KHz~150KHz.

E.g.

frequency display: 100 indicates PWM output 100Hz pulse;
1.01 represents the pulse of PWM output 1.01K.
54.1 represents the pulse of PWM output 54.1KHz.
1.2.4 indicates the pulse of PWM output 124KHz.
Duty cycle: 0~100%;
All settings are saved by power off.

Parameter

Frequency Range:1 Hz~150 K Hz
Working Voltage:3.3~30 V
Frequency accuracy:about 2%
Signal load capacity:the output current can be around 5~30 ma
Output amplitude:The PWM amplitude is equal to the supply voltage
Ambient temperature:-20~+70°C
Packaging Size:10*8*5 cm

Serial port communication:
The module has 4 independent buttons for setting the frequency and duty cycle.
It supports short press (increase or decrease one unit) and long press (fast increase or decrease).
It is very simple. The parameters are automatically saved after setting. Lost.

Scope of application:

1. Used as a square wave signal generator to generate a square wave signal for experimental development;
2. Used to generate a square wave signal that controls the motor driver;
3. Generate adjustable pulses for use by the MCU; control related circuits (applications such as PWM dimming speed regulation).
