iButton click is an iButton™ probe Click board™. The iButton is based on Analog Device's 1-Wire® communication protocol and a chip usually packed in a robust stainless steel casing. The button-shaped iButton device has two contacts the lid and the base. These contacts carry the necessary connections down to a sensitive silicone chip, embedded inside the metal button.
