Product Description
The NE555 Pulse Frequency Duty Cycle Adjustable Module Square Wave Signal Generator is a device that produces a 5 V square wave signal. This signal can be used for experimental development or for driving a stepper motor with a square wave drive signal.
The module allows fine-tuning of the output duty cycle. However, the duty cycle and the frequency are not independent of each other. Changing the duty cycle will also affect the frequency.
The output frequency is adjustable:
- Period T = 0.7 (RA +2 RB) C
- RA, RB is 0-10K adjustable.
- Low profile when C = 0.001UF.
- IF stalls C = 0.1UF.
- High-frequency file C = 1UF.
- HF stalls C = 100UF.
- So, buyers can calculate the frequency of the waveform.
Features
- Generate an adjustable pulse for MCU.
- Generate an adjustable pulse, to control circuitry associated.
- The output current can be 15 MA around; when 12V power supply, the output current can 35 MA around
- Output with LED indication(low level, LED will on; high level, LED will off; low frequency, the LED flashes).
- Max Output Current: >= ≥15MA (5V power supply, V-PP greater than 50%), >=35MA (12V power supply, V-PP greater than 50%)
Application
- 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 an adjustable pulse for MCU.
- Generate an adjustable pulse, to control circuitry associated.
