Description
NE555 Pulse Frequency Duty Cycle Adjustable Module Square Wave Signal Generator
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%), Â >=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 requency 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;
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.
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 adjustable pulse for MCU.
- Generate adjustable pulse,to control circuitry associated.
