The TTP224 is a touchpad detector IC which offers 4 touch key. The touching detection IC is designed for replacing the traditional direct button key with a diverse pad size. Capacitive touch allows electronics to sense when your finger is within a few millimetres of a surface to simulate a button “press” just like how the pushbutton works. Capacitive sensing may be used in any place where low to no force human touch sensing is desirable. Features: On-board TTP224 capacitive touch induction IC On-board 4-Channel level indicator. Adjustable output mode, key output mode, longest time and fast/low power output. Package Includes: 1 x TTP224 4-Channel Capacitive Touch Switch Module.
