2PCS NE555 pulse frequency duty cycle adjustable modulesquare/rectangular wave signal generatorstepping motor driver



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: !#!gt!*!=100MA
Output amplitude: 4.2V V-PP to 11.4V V-PP. (Different input voltage the output amplitude will be different)
Maximum output current: !#!gt!*!=15MA (5V power supply V-PP greater than 50%)
!#!gt!*!=35MA (12V power supply V-PP greater than 50%)
Output with LED indication(low level LED will on; high levelLED 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 generatorgenerates 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 pulseto control circuitry associated.
