NE555 Timer Module (Square Wave Signal Generator)

Description

NE555 Timer Module is a 5 V square wave signal generator. It generates a square wave signal used for experimental development. Also, use to drive a stepper motor, PWM Controlled BLDC Motors 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:

1. Period T = 0.7 (RA +2 RB) C
2. RA, RB is 0-10K adjustable;
3. Low profile when C = 0.001UF;
4. IF stalls C = 0.1UF;
5. High-frequency file C = 1UF;
6. HF stalls C = 100UF;

Application:

• Used in Speed Control or PWM 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.

Specifications:

1. The output current can be 15mA around; when 12V power supply, the output current can 35 mA
2. Output with LED indication(low level – LED will ON; High level – LED will OFF; Low frequency – the LED flashes).
3. Max Output Current: >= ≥15mA (5V power supply, V-PP greater than 50%), >=35mA (12V power supply, V-PP greater than 50%)

Package Includes :

1 x NE555 Timer Module (Square Wave Signal Generator)
