PCB Key Chain

The PCB keychain is a compact and portable electronic device that combines functionality and style. It features a custom-designed printed circuit board (PCB) integrated into a keychain form factor. The keychain incorporates six 3mm LEDs, a coin cell holder, and a switch, creating an eye-catching accessory with practical applications.

The primary feature of the PCB keychain is the array of six 3mm LEDs. These LEDs are carefully arranged on the PCB to provide a visually appealing light display. Whether you want to showcase your favorite colors, create mesmerizing patterns, or simply illuminate your surroundings, the LEDs offer a vibrant and customizable lighting experience.

To power the LEDs, the keychain is equipped with a coin cell holder. This holder securely houses a small coin cell battery, providing the necessary power for the LEDs to operate. The coin cell holder is designed to be easily accessible, allowing for convenient battery replacement when needed.

To control the LED illumination, a switch is integrated into the PCB keychain. This switch allows you to toggle the LEDs on or off with a simple press, conserving battery life and offering control over when and where you want the light display to be active. The switch is positioned ergonomically, ensuring easy operation while maintaining the compact form factor of the keychain.

The PCB keychain is not only a functional device but also a fashionable accessory. The compact size and sleek design make it an ideal addition to your keyring, backpack, or purse. It serves as a conversation starter, showcasing your love for technology and creativity.

Whether you want to add a touch of personalization to your belongings, have a handy source of light in dark environments, or simply express your style, the PCB keychain with its six 3mm LEDs, coin cell holder, and switch provides an innovative and visually appealing solution. It combines practicality, design, and technology in a portable and versatile package, making it a must-have accessory for electronics enthusiasts and those seeking a unique and functional keychain.
