Capacitive Touch Sensor Button TTP223

This small capacitive touch sensor replaces a push button. It works from 2.5 V and therefore suits 3.3 V and 5 V microcontrollers as well as the Raspberry Pi. As supplied, the I/O output goes high on touch. Solder bridges allow it to work as a switch or with an inverted level.
