TTP224 4-Way Capacitive Touch Switch Module

The TTP224 4-Way Capacitive Touch Switch Module is a touch input board that provides four independent capacitive touch keys. It uses the TTP224 capacitive touch sensor IC to detect finger touch, converting touch events into digital outputs without mechanical buttons. The board is suitable for low power touch control interfaces in embedded systems.

This module is ideal for home automation panels, touch user interfaces, access control, interactive installations, and microcontroller based projects where compact touch inputs replace traditional switches. The touch sensing provides reliable performance and easy interfacing with digital logic systems.
