TTP229 16 Channel Capacitive Touch Sensor Module (16-Key Capacitive Touch Keypad Module)

The TTP229 16 Channel Capacitive Touch Sensor Module is a multi-key touch keypad designed to replace traditional mechanical switches with capacitive touch inputs. Based on the TTP229 touch controller IC, it provides sixteen independent touch-sensitive channels and communicates through a two-wire serial interface, reducing the number of I/O pins required on the host microcontroller. The module is compatible with Arduino, ESP32, ESP8266, STM32, Raspberry Pi, and other development platforms, making it ideal for touch control panels, password keypads, home automation, interactive devices, and embedded electronics projects.
