TTP223 Touch button Module

SKU: S018

The TTP223 Touch Key Module is based on a touch-sensing IC (TTP223) capacitive touch switch module. A capacitive touch sensor module based on the dedicated TTP223 touch sensor IC. The module provides a single integrated touch sensing area of 11 x 10.5mm with a sensor range of ~5mm.The TTP223 is a touchpad detector IC replicating a single tactile button. This touch detection IC is designed for replacing traditional direct button key with diverse pad size.
