NE555 Frquency Adjustable Pulse Generator Module

Description:- 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.
