DAOKAI NE555 Pulse Generator 5Pcs – Frequency with Dupont Cable

Description

Product Overview

The DAOKAI NE555 Pulse Generator is a compact, high‑performance module designed for precise timing and signal generation in a wide range of electronic applications. Built around the classic NE555 integrated circuit, the module delivers a clean rectangular wave with a duty cycle close to 50 %, ensuring consistent pulse widths for reliable operation. The device operates on a flexible supply voltage range of 5 V to 12 V, making it compatible with common battery packs, USB power sources, and regulated bench supplies. Its output stage can source up to 225 mA (maximum), allowing direct driving of LEDs, small relays, or other low‑power loads without the need for additional driver circuitry. The included Dupont cable simplifies wiring to development boards such as Arduino, Raspberry Pi, or any microcontroller with standard 0.1 in (2.54 mm) header spacing.

Key specifications include a compact footprint of 0.47 × 0.51 × 0.51 in (12 × 13 × 13 mm) and a lightweight design of just 1.06 oz (30 g), enabling easy integration into breadboards, prototype enclosures, or portable test rigs. The module’s frequency range spans from 5 Hz to 2 kHz, adjustable via a built‑in potentiometer; users can also modify the range by swapping the external capacitor C1, offering flexibility for specialized experiments. Rise and fall times are specified at 100 ns, providing sharp transitions suitable for digital logic testing and edge‑triggered circuits. The product is identified by model number WE‑DA‑108 and carries the DAOKAI brand reputation for reliable industrial‑grade components.

Usage

This pulse generator excels in educational settings, hobbyist workshops, and professional prototyping environments. In university laboratories, instructors can demonstrate fundamental concepts such as timing, pulse width modulation, and oscillator behavior using a single, easy‑to‑configure module. Hobbyists building DIY projects—ranging from LED chasers and motor speed controllers to simple communication protocols—will appreciate the straightforward frequency adjustment and the ready‑made Dupont cable that eliminates the need for custom wiring.

For engineers developing embedded systems, the module serves as a convenient test signal source when evaluating input capture peripherals, interrupt handling, or signal conditioning circuits. Its ability to produce a stable 50 % duty cycle waveform simplifies the verification of PWM‑controlled devices, while the adjustable frequency range supports a variety of timing requirements, from slow blinking indicators to faster data‑rate simulations. The compact size allows the generator to be mounted directly on a PCB prototype or placed within a handheld test kit for field diagnostics.

Because the unit operates from 5 V to 12 V, it can be powered directly from common development board outputs, battery packs, or regulated supplies, providing flexibility for portable or stationary applications. The high output current capability means that users can drive small loads without additional transistors, reducing circuit complexity and component count. Whether you are designing a stepper‑motor driver, creating a simple alarm system, or conducting a graduation design project, this NE555 module offers a reliable, low‑cost solution.

FAQ

What supply voltage range does the module accept?

The NE555 Pulse Generator operates safely from 5 V up to 12 V, making it compatible with most development boards, battery packs, and regulated power supplies.

Can I change the frequency range beyond 5 Hz‑2 kHz?

Yes. While the built‑in potentiometer provides the default 5 Hz‑2 kHz range, you can modify the external timing capacitor (C1) to extend the lower or upper limits according to your specific needs.

Is the output suitable for driving a small DC motor?

The module can source up to 225 mA, which is sufficient for driving small DC motors or motor driver inputs. For larger motors, an external driver transistor is recommended.

How do I connect the module to an Arduino board?

Use the included Dupont cable to connect the module’s power pins to the Arduino’s 5 V and GND, and connect the output pin to any digital input pin. You can then read the pulse using interrupt or digitalRead functions.

What warranty does DAOKAI provide?

DAOKAI offers a standard one‑year warranty covering manufacturing defects, along with access to technical support for troubleshooting and usage guidance.
