SPI Isolator 2 Click is a compact add-on board that contains a digital isolator optimized for a serial peripheral interface. This board features the ISO7741, a high-performance quad-channel digital isolator with a double capacitive silicon dioxide insulation barrier capable of galvanic isolation up to 5000Vrms from Texas Instruments. The ISO7741 provides high electromagnetic immunity and low emissions at low power consumption while isolating digital I/Os. It has three forward and one reverse-direction channel with enable pins that can be used to put the respective outputs in Hi-Z state. This Click board™ provides a simple, compact solution for isolated SPI data communication.
SPI Isolator 2 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.

DS1990A is a unique serial number identification iButton™. The iButton is a technology based on the one-wire communication protocol, and a chip packed in a robust stainless steel casing. This button shaped 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 one-wire interface. The communication is almost instant, so it is enough to press the iButton lightly to the probe contacts.
