NE555 pulse frequency, duty cycle adjustable module,square/rectangular wave signal generator,stepping motor driver

Description

Is used as a square wave signal generator generates a square wave signal used for experimental development.

To drive a stepper motor for generating a square wave drive signal.

Adjustable pulse generated for use by MCU.

Adjustable pulse generation, control circuitry associated.

Description:

Size: 3.1CM * 2.3CM

The main chip: NE555;

Input voltage: 5V-15VDC. 5V power supply, the output current can 15MA around; 12V power supply, the output current can 35MA around;

The input current: 100MA

The output amplitude: 4.2V V-PP to 11.4V V-PP. (Different depending on the input voltage, the output amplitude will be different)

The maximum output current: 15MA (5V power supply, V-PP greater than 50%), 35MA (12V power supply, V-PP greater than 50%)

Advantages:

The output with LED indication, there is no output straightforward (low LED volume, high LED off frequency is relatively low, the LED flashes);

The output level selectable frequency range, the output frequency is more continuously adjustable:

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 the frequency of the waveform buyers can own calculations.
