NE555 Pulse Adjustable Module Square Wave Signal Generator,Default NO

Applications:

1. Used as a square wave signal generator to generate square wave signals for experimental development.

2. Used to generate a square wave signal that drives the stepper motor driver.

3. Generate adjustable pulses for use by the MCU.

4. Generate adjustable pulses to control the associated circuit.

Adevantages:

1, the output with LED indication,

2. The output frequency range is optional, so that the output frequency is more continuously adjustable;

Low frequency file: 1Hz ~ 50Hz

Medium frequency file: 50Hz ~ 1kHz

Medium and high frequency files: 1KHz ~ 10kHz

High frequency file: 10kHz ~ 200kHz

3, the output duty cycle can be fine-tuned

4, the output frequency is adjustable;

The period T=0.7 (RA+2RB) CRA, RB is 0-10K adjustable;

C=0.001UF in low frequency gear;

C=0.1UF in the intermediate frequency file;

Medium and high frequency file C=1UF;

C=100UF in high frequency gear
