NE555 Pulse Frequency Duty Cycle Adjustable Module
Features: Size: 31mm x 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%)£¬ >=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.
