TTP223 Touch Key Module (Capacitive Touch Switch Sensor Module)

The TTP223 Touch Key Module is a compact capacitive touch switch designed to replace conventional mechanical push buttons in electronic circuits. Based on the TTP223 capacitive touch sensor IC, it detects finger touch through capacitive sensing technology and generates a digital output signal without requiring physical button movement. Operating from 2.0V to 5.5V, the module is compatible with Arduino, ESP32, ESP8266, STM32, Raspberry Pi, and other microcontroller platforms. It is ideal for touch control panels, home automation, consumer electronics, smart appliances, and embedded system applications.
