The TTP223 Capacitive Touch Key Module is built around the TTP223 touch-sensing IC and functions as a digital touch switch. It features a single touch-sensitive area measuring 11 x 10.5mm, with a typical sensing range of approximately 5mm.

An onboard LED provides visual feedback when the sensor is activated. By default, the output remains low and switches to high upon touch. Configurable solder jumpers allow you to change the output mode to either active low or toggle.

Designed to mimic the function of a tactile push button, this module offers a modern, reliable alternative to mechanical switches. It can be easily integrated into various projects where simple touch input is required.
