AM-143 NE555 Adjustable Pulse Frequency Duty Cycle Module Square Wave Signal Generator
This is an adjustable square wave signal generator with pulse frequency duty cycle.
Features:
- Generates a square wave signal used for experimental development.
2. Used to drive a stepper motor for generating a square wave drive signal.
3. Generates adjustable pulse for MCU.
4. Generates adjustable pulse, to control circuitry associated.
Specifications:
5. Size: 31mm x 22mm
6. Main chip: NE555
7. 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
8. Input current: >=100 MA
9. Output amplitude: 4.2V V-PP to 11.4V V-PP. (Different input voltage, the output amplitude will be different)
10. Maximum output current: >=15MA (5V power supply, V-PP greater than 50%), >=35MA (12V power supply, V-PP greater than 50%)
11. Output with LED indication (low level, LED will on; high level, LED will off; low frequency, the LED flashes)
12. The output frequency range is selectable:
LF file: 1Hz ~ 50Hz
IF file: 50Hz ~ 1kHz
High-frequency file: 1KHz ~ 10kHz
HF file: 10kHz ~ 200kHz
13.The output duty cycle can fine-tune; duty cycle and frequency is not separately adjustable; adjusting the duty cycle will change the frequency
