Adjustable PWM Signal Generator Module - Square and Rectangular Wave XYLPWM

Welcome to our shop! This Signal Generator Module is designed to be used as a square wave signal generator for experimental development and controlling motor drivers. It can also generate adjustable pulses for MCU use and control related circuits, such as PWM dimming and speed regulation. This module is easy to operate, with PWM output. It allows you to set the frequency and duty cycle separately, providing a wide frequency range and high accuracy. The frequency and duty cycle are displayed clearly on the LCD screen, and the module can communicate with a serial port. All setting parameters are saved even after power off. The frequency range is divided into four categories, with automatic switching: - XXX (without decimal point): the smallest unit is 1Hz, ranging from 1Hz to 999Hz. - X.XX (one hundred decimal point): the minimum unit is 0.01KHz, ranging from 1.00KHz to 9.99KHz. - XX.X (ten in decimal): the minimum unit is 0.1KHz, ranging from 10.0KHz to 99.9KHz. - X.X.X (decimal in ten and one hundred): the minimum unit is 1KHz, ranging from 1KHz to 150KHz. The module has the following parameters: - Working Voltage: 3.3 ~ 30V - Frequency range: 1Hz ~ 150KHz - Frequency accuracy: about 2% in each range - Load capacity signal: output current of about 5 ~ 30mA - Output amplitude: PWM amplitude equal to the supply voltage - Ambient temperature: -20 ~ +70 ℃ - Serial Port Control (MCU TTL level communications) with communication standard: 9600 bps, 8 data bits, 1 stop bit, no parity bit, and no flow control. To set the PWM frequency, you can use the following format: - "F101": Set the frequency to 101Hz (ranging from 001 to 999). - "F1.05": Set the frequency to 1.05KHz (ranging from 1.00 to 9.99). - "F10.5": Set the frequency to 10.5KHz (ranging from 10.0 to 99.9). - "F1.0.5": Set the frequency to 105KHz (ranging from 1.0.0 to 1.5.0). To set the PWM duty ratio, you can use the following format: - "DXXX": Set the PWM duty cycle to XXX (ranging from 001 to 100). For example, "D050" sets the PWM duty cycle to 50%. You can also send the "read" command to read the set parameters. A successful read operation will return "DOWN", while a failed read operation will return "FALL". 100% Satisfaction: Our customers are our top priority.
