SPI Isolator 9 Click is a compact add-on board designed for secure and reliable SPI communication across isolated domains. This board features the 4DIR1421H, a quad-channel digital isolator from Infineon, known for precise data communication and low power consumption. Featuring Infineon's ISOFACE™ Coreless Transformer (CT) technology, it provides exceptional noise immunity with a minimum CMTI of 100kV/µs, supports data rates up to 40Mbps, and withstands isolation voltages up to 5700Vrms, ensuring safety and efficiency in industrial environments. Its innovative Click Snap feature allows flexible implementation and autonomous operation by breaking the PCB along designated lines. SPI Isolator 9 Click is ideal for applications in industrial automation, motor drives, server and telecom systems, Switch-Mode Power Supplies (SMPS), and medical devices.

SPI Isolator 9 Click is fully compatible with the mikroBUS™ socket and can be used on any host system supporting the mikroBUS™ standard. It comes with the mikroSDK open-source libraries, offering unparalleled flexibility for evaluation and customization. What sets this Click board™ apart is the groundbreaking ClickID feature, enabling your host system to seamlessly and automatically detect and identify this add-on board, alongside a Click Snap feature introducing a new level of flexibility and ease of use.
