NE555 Adjustable Signal Generator – Pulse Frequency & Duty Cycle Control Module

Description

• Main chip: NE555
• Input Voltage: 5V-15V DC.
• Generate an adjustable pulse for MCU.
• Generate an adjustable pulse, to control circuitry associated.

NE555 Pulse Frequency Duty Cycle Adjustable Module Square Wave Signal Generator is a 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. The duty cycle and frequency is not separately adjustable, adjusting the duty cycle will change the frequency.

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.
