NE555 Frequency Adjustable Pulse Module

NE555 Frequency Adjustable Pulse Generator Module

This is a very simple and compant module for generating square wave. It is based on NE555 IC and can be used to generate square wave pulses from about 4 Hz to 1.3 Khz, this can be used for experimental development, or driving a stepper motor, it would be also a good choice for users learning working of LM555 IC. 

Features

• Size : 31mm * 22mm;

• Main chip : NE555;

• Input Voltage : 5V-15VDC. when power supply is 5V , the output current can be 15MA around;when 12V power supply, the output current can 35MA around;

• Input current : >=100MA

• Output amplitude : 4.2V V-PP to 11.4V V-PP. (Different input voltage, the output amplitude will be different)

• Maximum output current : >=15MA (5V power supply, V-PP greater than 50%),                                                                 

                                                           >=35MA (12V power supply, V-PP greater than 50%)

• Output with LED indication(low level ,LED will on; high level,LED will off;low frequency, the LED flashes);

• The output frequency range is selectable :   

            LF file : 1Hz ~ 50Hz
            IF file : 50Hz ~ 1kHz
            High - frequency file: 1KHz ~ 10kHz
            HF file : 10kHz ~ 200kHz

• The output duty cycle can fine-tune;duty cycle and frequency is not separately adjustable ; adjusting the duty cycle will change the frequency

Application

• As a square wave signal generator,generates a square wave signal used for experimental development.

• Used to drive a stepper motor for generating a square wave drive signal.

• Generate adjustable pulse for MCU.

• Generate adjustable pulse,to control circuitry associated.

Package includes:

• 1 x NE555 Pulse Frequency Duty Cycle Adjustable Module Square Wave Signal Generator
