Cyberpunk Dual PCB Necklace: Functional Audio & Sensor Pendants, functional cyberpunk sci-fi necklace, Laser rangefinder, radio pcb necklace, can insert earphone and USB

The Curator's Note I have always appreciated the intricate, raw beauty of exposed hardware. I curated this dual-pendant necklace for the unapologetic tech enthusiast or cyberpunk fan. The best part? These aren't just aesthetic props—they are actual, functional circuit boards. Whether you wear them purely as a sci-fi statement piece or take them off to prototype a new development board project, this is hardware you can literally wear.

The Details

• The Main Board (VHM-314): A fully functional Bluetooth audio receptor. When powered via the micro-USB port, a blue indicator light turns on, allowing you to pair it with your phone and listen to music through the 3.5mm earphone jack. (Dimensions: 3 cm x 3 cm).

• The Secondary Board: An RGB motion detection sensor board (GY-9960-3.3 APDS-9960). Note: There are 3 distinct layouts for this purple PCB; you will receive one variation at random. (Dimensions: 2 cm x 1.5 cm).

• The Chain: Comes standard with a 70 cm chain.

• The Developer's Note: If you have the knowledge, you can absolutely wire these up for development (typically with an Arduino). Please note that no technical instructions or support are provided!

Wear & Care Instructions To maintain the quality of your hardware jewelry, please observe the following:

• Moisture is the Enemy: Circuit boards and water do not mix. Remove before showering, swimming, or exercising.

• Chemicals: Avoid direct contact with perfumes, lotions, and harsh chemicals. Polish gently with a soft, dry cloth.

• Allergy Alert & Disclaimer: The standard chain and metal finishes may contain nickel. If you have a known metal allergy, please purchase one of our Sterling Silver upgrade chains instead.
