Click Boards Catalog

iButton click - is an iButton™ probe Click board™. The iButton is a Analog Devices technology based on Analog'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. When the iButton touches the reader probe on the Click board™, it establishes the communication with the host MCU, via the 1-Wire® interface. The communication is almost instant, so it is enough to press the iButton lightly to the probe contacts.

Note: The Click board™ comes with Analog's DS1990A, a serial number iButton™ device with a unique 64-bit serial number. For more information on the serial number iButton™ device, please visit the official product page.
