The Atmel® QT3 Xplained Pro is an extension board, which enables the evaluation of a capacitive touch 12 key numpad in mutual capacitance configuration. The board is designed to use the Peripheral Touch Controller (PTC) in Atmel microcontrollers. The board shows how easy it is to design a capacitive touch solution for the PTC without the need for any external components. The kit includes one board with a 3 by 4 touch key matrix and a 4 by 4 LED matrix for a visual feedback of the touch.
