Adjustable Square Wave Pulse Generator for Electronic Circuits and Microcontrollers
A compact digital PWM signal generator with an LCD display, designed to produce square-wave pulses with adjustable frequency and duty cycle. It supports a wide frequency range from 1 Hz to 150 kHz and duty cycle adjustment from 0% to 100%.
The built-in display shows the selected parameters, while the control buttons allow convenient adjustments. The generator also supports UART serial communication for setting and reading operating parameters. Settings are retained when the power is disconnected.
Main specifications:
• Operating voltage: DC 3.3–30 V
• Frequency range: 1 Hz – 150 kHz
• Frequency accuracy: ±2%
• Duty cycle adjustment: 0–100%
• Output current: approximately 5–30 mA
• Output amplitude: equal to the supply voltage
• LCD display
• UART serial communication
• Settings memory after power loss
The generator is suitable for laboratory experiments, electronic circuit development and testing, generating pulses for microcontrollers, and providing control signals to PWM motor drivers. It can also be used when testing electronic circuits for lighting dimming and motor speed control.
Important: This is a PWM square-wave pulse generator, not a general-purpose analog function generator for sine or triangular waveforms. Its output is intended for signal control and cannot directly power motors, LED strips, or other high-current loads. When connecting it to a microcontroller, make sure the output amplitude does not exceed the controller's permitted input voltage.
