NE555 Frequency Adjustable Pulse Generator Module
The NE555 Frequency Adjustable Pulse Generator Module is a square wave pulse generator based on the ubiquitous NE555 timer IC.
The module can be powered from a wide power supply range (4.5 to 12V) and will produce a continuous square wave output between 15Hz to 24KHz which can be adjusted via the on-board multi-turn potentiometer.
Useful for where an approximate frequency clock source is required such as for stepper motor step generation tone generation etc.
