Giới thiệu Mô Đun Phát Tín Hiệu Điều Chỉnh Tần Số Ne555

Features:
-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.
-Size: 31mm * 22mm;
-Main chip: NE555;
-Input Voltage: 5V-15V DC. when power supply is 5 V , the output current can be 15 MA around;when 12V power supply, the output current can 35 MA around;
-Input current: >=100 MA
-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;
Package including:
1 x NE555 Pulse Frequency Duty Cycle Adjustable Module
