Package Included

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

Description

1. As a square wave signal generator generates a square wave signal used for experimental development.
2. Used to drive a stepper motor for generating a square wave drive signal.
3. Generate an adjustable pulse for MCU.
4. Generate adjustable pulse, to control circuitry associated.
5. Input Voltage: 5V-15V DC. When a power supply is 5V, the output current can be 15 MA around; when 12V power supply, the output current can 35 MA around
6. Input current: >=100 MA
7. Output amplitude: 4.2V V-PP to 11.4V V-PP. (Different input voltage, the output amplitude will be different)
8. Maximum output current: >=15MA (5V power supply, V-PP greater than 50%), >=35MA (12V power supply, V-PP greater than 50%)
9. Output with LED indication(low level, LED will on; high level, LED will off; low frequency, the LED flashes)
10. The output frequency range is selectable:
LF file: 1Hz ~ 50Hz
IF file: 50Hz ~ 1kHz
High-frequency file: 1KHz ~ 10kHz

HF file: 10kHz ~ 200kHz
