TTP229 16 Channel Capacitive Touch Sensor Module

The TTP229 16-Channel Capacitive Touch Sensor Module provides 16 independent touch-sensitive pads numbered 1–16, making it ideal for touch keypads, menu navigation, and interactive control panels in Arduino and microcontroller projects. Based on the TTP229 IC, it uses capacitive sensing technology — no physical press required, just a light touch. The module outputs digital signals via a serial interface (SDO/SCL).
