The Capacitive Touch Pad 16 is a versatile sensor module featuring 16 individual touch-sensitive pads powered by the reliable TTP229 touch-sensing IC. It’s designed to easily replace traditional mechanical buttons with sleek, modern capacitive input, giving your projects a cleaner, more professional look. Simply power it with 2.4 – 5.5 V DC, and all 16 pads become active and ready to detect touch. It’s perfect for Arduino, microcontrollers, or even standalone setups, responding smoothly when a finger or conductive object comes close to the pads.

What makes this module even more appealing is its flexibility—sense-pads can be extended with wires or crafted from nearly any conductive material, and it can even detect touch through glass, plastic, fabric, or wood. This allows you to hide controls in walls, furniture, or creative surfaces for seamless, intuitive designs. Ideal for custom control panels, home automation, interactive art, or modernizing any interface, the Capacitive Touch Pad 16 offers an easy way to upgrade your projects to sleek, touch-based interaction.
