1st NE555 fyrkants pulsgenerator. Inställbar frekvens & dutycycle
med 2st 3D- printade korthållare. ( Kan bli i annan färg än visad. )
NE555 Pulse Frequency Duty Cycle Adjustable Module Square Wave Signal Generator
Input Voltage: 5V-15VDC. when power supply is 5V , the output current can be around 15mA.
when 12V power supply, the output current can be around 35mA. Input current: >=100MA
Output amplitude: 4.2V V-PP to 11.4V V-PP.
The output amplitude will vary with the input voltage.
Maximum output current: >=15MA (when 5V power supply, V-PP greater than 50%),
>=35MA (when 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 frequency range is selectable.
LF 1Hz~50Hz.50Hz~1kHz. 1KHz ~ 10kHz. 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.
Generating a square wave signal used to drive a stepper motor.
Generate adjustable pulse for MCU.
Generate adjustable pulse, to control circuitry associated.
Storlek ca: 3.1 x 2.4cm
Levereras med korthållare. ( 3D- utskrift i PETG.)
