1) Main chip: NE555
2) Input Voltage: 5V-15V DC.
3) Generate an adjustable pulse for MCU.
4) Generate an adjustable pulse, to control circuitry associated.
Description:
NE555 Pulse Frequency Duty Cycle Adjustable Module Square Wave Signal Generator is 5 V square wave signal generator. It generates a square wave signal used for experimental development. Also, use to drive a stepper motor for generating a square wave drive signal. 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.
Applications:
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 an adjustable pulse for MCU.
Generate an adjustable pulse, to control circuitry associated.
Features:
Generate an adjustable pulse for MCU.
Generate an adjustable pulse, to control circuitry associated.
The output current can be 15 MA around; when 12V power supply, the output current can 35 MA around
Output with LED indication(low level, LED will on; high level, LED will off; low frequency, the LED flashes).
Max Output Current: >= ≥15MA (5V power supply, V-PP greater than 50%), >=35MA (12V power supply, V-PP greater than 50%)
Package Include:
1 x Square/Pulse Generator NE555 Frequency Adjustable Module.
