16 Channel - Touch Sensor Module Board (TTP229 Touch Key / Capacitive Touch Switch)

16 Channel TTP229 Capacitive Touch Sensor Module Board

The 16 Channel TTP229 Capacitive Touch Sensor Module is a versatile input solution for your electronics projects. It is built around the TTP229 touch-sensing IC, offering 16 independent touch keys. This module provides a reliable and stable alternative to traditional mechanical switches. An onboard LED indicates when a sensor is triggered, offering immediate visual feedback. Users can easily reconfigure its operation mode via solder jumpers, supporting both active low or toggle output. With features like momentary or latching modes and adjustable sensitivity, it's highly adaptable. This high-quality module is perfect for creating intuitive user interfaces and integrating touch functionality into various applications. Enhance your designs with responsive and modern touch control.
