NE555 Frequency Adjustable Pulse Generator Module

NE555 Frequency Adjustable Pulse Generator Module 

The NE555 Frequency Adjustable Pulse Generator Module is a small, easy-to-use board based on the popular NE555 timer IC.
It is designed to generate adjustable square-wave pulses with controllable frequency and duty cycle.
Using onboard potentiometers, you can fine-tune the signal output, making it useful for testing circuits, driving motors, LEDs, servos, and more.

The module outputs a clean square wave signal and can be used as a standalone function generator for many electronics experiments. It operates on a 5V–15V supply, making it compatible with a wide range of projects.
