NE555 Duty Cycle Adjustable Pulse Frequency Module Square Wave Signal Generator Description 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%), >=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.
