HW-753 PWM Signal Generator - LCD display - XY - LPWM Arduino
PWM signal generator. Wide frequency range, high accuracy. A wide range of voltages allows the use and testing of many electrical and electronic devices. Additional TX and RX UART serial communication output.
The PWM signal generator will find many applications in our projects. First of all, we can use it to create square waveforms, which will be useful in diagnosing electronics, controlling DC motors or lighting, and even generating a clock for most microcontrollers.
This product is equipped with four buttons that are responsible for the frequency and adjustment of the PWM signal fill. In addition, it also has holes for pins in a standard 2.54 mm raster with which we can connect the voltage and output the PWM signal.
The generator has a large and clear LCD display, where the frequency is described by four modes: without a dot - up to 999Hz, with two decimal places - up to 9.99KHz, with one decimal place - up to 99.9KHz and with two dots - up to 150KHz.
