TTP224 4-way Switch / Touch Sensor / Capacitive Touch Sensor Module

Description

The TTP224 is a touch pad detector IC which offers 4 touch key. The touching detection IC is designed for replacing traditional direct button key with diverse pad size. Capacitive touch allows electronics to sense when your finger is within a few millimeters of a surface to simulate a button “press” just like how the push button works. Capacitive sensing may be used in any place where low to no force human touch sensing is desirable.
