HQ NE555 pulse frequency, duty cycle adjustable module motor stepper

Detail HQ NE555 pulse frequency, duty cycle adjustable module motor stepper

hai kak. Mohon maaf untuk minimal order 20 ribu ya kak baru bisa kita proses, diluar ongkirSTOCK per 31 maret = 20 PCS

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.\
