NE555 Pulse Frequency Duty Cycle Adjustable Module

NE555 Pulse Frequency Duty Cycle Adjustable Module Square Wave Signal Generator is 5 V square wave signal generator. It generates a square wave signal used for experimental development. Also, use to drive a stepper motor for generating a square wave drive signal.The output duty cycle can fine-tune. Duty cycle and frequency is not separately adjustable, adjusting the duty cycle will change the frequency.

Input Voltage: 5V-15V DC.

The output frequency is adjustable:

Period T = 0.7 (RA 2 RB) C

RA, RB is 0-10K adjustable;

Low profile when C = 0.001UF;

IF stalls C = 0.1UF;

High-frequency file C = 1UF;

HF stalls C = 100UF;

So buyers can calculate the frequency of the waveform.
