NE555 Frequency Adjustable Pulse Generator Module

A single-channel signal output, the output is approximately fifty percent duty cycle square wave;
Onboard adjustable resistance, adjust the output frequency can be controlled resistance;
On-board power indicator. The working voltage: 5 ~ 12V;
Board size: 29 (mm) x12 (mm);
Onboard chip NE555A single channel output, square wave pulse generator module 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 set by on on-board multi-turn potentiometer. Useful for applications where an approximate frequency clock source is required such as for stepper motor step generation tone generation etc.
