FNIRSI-PWM Square / Rectangular Wave Signal Generator

Precise PWM and Square Wave Output in Your Pocket
The FNIRSI-PWM Square Wave Rectangular Wave Signal Generator is a compact, versatile tool for engineers, makers, repair technicians and electronics hobbyists who need a reliable test signal on the bench or in the field. Small enough to fit in your pocket but powerful enough for serious work, it outputs clean PWM, square and rectangular waveforms for testing circuits, microcontroller projects, driver boards, audio paths and more.

Whether you’re developing new hardware, troubleshooting a project, or teaching electronics, this handy generator gives you a quick, consistent signal source without needing a full-size bench instrument. It’s perfect for labs, workshops, classrooms and on-site service calls.

Adjustable PWM, Frequency and Duty Cycle
At the core of the FNIRSI-PWM is its flexible pulse-width modulation and square wave output. You can adjust frequency and duty cycle over a wide range (model-dependent), allowing you to simulate clock signals, control logic pulses, drive LEDs, test motor drivers or mimic microcontroller outputs.

Fine-tuning duty cycle makes it easy to explore how your circuits respond to different PWM ratios—useful for dimming tests, speed control, switching circuits and digital input testing. This level of control helps you diagnose problems quickly and refine designs more efficiently.

Clear Interface and Simple Operation
Designed to be user-friendly, the FNIRSI-PWM generator typically features a clear display and straightforward buttons or controls, so you can set frequency, duty cycle and waveform type without a steep learning curve. Values are shown directly on the screen, making it easy to match requirements from datasheets or test procedures.

The intuitive interface is especially helpful for students, beginners and busy technicians who need to set up signals fast. You spend less time navigating confusing menus and more time actually testing and fixing circuits.

Compact, Portable and USB-Powered Convenience
With its compact body and light weight, this signal generator is easy to carry between workstations, classrooms, job sites or home labs. It fits comfortably in a toolkit, backpack or desk drawer, always ready when you need a quick test source.

USB power (model-dependent) means you can run it from a power bank, laptop, bench supply or USB adapter without needing a bulky dedicated power brick. This makes it ideal for mobile work, field repairs and hobby benches where space and sockets are limited.

Essential Tool for DIY Electronics and Professional Use
From simple logic testing and timing experiments to development of PWM-controlled circuits, the FNIRSI-PWM Square Wave Rectangular Wave Signal Generator is a practical, budget-friendly alternative to larger lab gear. It gives you the control and flexibility needed for everyday electronic debugging and design, all in a portable, easy-to-use package.
