NE555 Frquency Adjustable Pulse Generator Module

NE555 Frequency Adjustable Pulse generator Module utilizes the NE555 timer IC to generate pulses from about 4Hz to 1.3Khz, which can be used for experimental development, or driving a stepper motor, it would be also a good choice for users learning& experiencing the analog RC circuits.

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;

Applications:-

• 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.
