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.

SPI Isolator Click is a compact add-on board with a digital isolator optimized for a serial peripheral interface. This board features the ADuM4154, a 5kV digital isolator optimized for a serial peripheral interface (SPI) from Analog Devices. Based on the iCoupler® chip scale transformer technology, the low propagation delay and jitter in the SCLK, SI, SO, and SSS SPI bus signals support SPI clock rates of up to 17MHz.It also provides a slave select multiplexing system that allows up to four slave devices to be serviced from one isolator. When a target slave is selected, the slave select signal propagates to the desired output with low propagation delay, allowing tight timing control. This Click board™ is suitable for general SPI-bus isolation, industrial automation systems, sensor isolation, and many other applications.
SPI Isolator Click is supported by a mikroSDK compliant library, which includes functions that simplify software development. This Click board™ comes as a fully tested product, ready to be used on a system equipped with the mikroBUS™ socket.
