TTP226 8-way Capacitive Touch Switch Module

The TTP226 8-way Capacitive Touch Switch module gives you eight touch-sensitive keys on one small board. Based on the TTP226 touch detector IC, it senses a finger on each pad and switches the matching digital output, so you can replace mechanical push buttons with smooth, sealed touch keys in Arduino, ESP32 and Raspberry Pi projects.

What's in the Box

• 1 × TTP226 8-way capacitive touch module

Tip: Read each output with a digital input pin and share a common ground with your board. Capacitive pads can sense through a thin non-metal panel such as plastic or acrylic, so you can mount the module behind a front cover; test the sensitivity with the cover in place.
