MIKROE-2883

Cap Extend 3 click board™ features four capacitive sensor pads integrated on the PCB that can sense touch through a variety of different materials. This click can sense touch through plastic, wood or even metal. All these materials can be used to protect the surface of the PCB and sensor pad traces allowing implementation of all kinds of human machine interfaces and seamless integration of the touch sensitive buttons into various kinds of front panels. The click also features a connector used for connecting to external sensors. It can be used as a reliable replacement for buttons or switches in many applications, including light switches, office equipment and toys, display and keypad backlight activation and similar.
