The TTP229 16-Way Capacitive Touch Switch Module is a digital touch sensor keypad based on the TTP229 IC, designed to easily integrate capacitive touch input into your projects. It features 16 highly sensitive touchpads, making it an excellent modern replacement for traditional mechanical keypads.

Capacitive touch technology enables the detection of a finger approaching within a few millimeters of the surface, simulating a button press without physical force. This makes it ideal for applications where a low-force or contactless interface is desired.
