MIKROE SPI Isolator Click carries the ADuM4154 5kV digital isolator optimized for a serial peripheral interface (SPI), from Analog Devices. The click is designed to run on either 3.3V or 5V power supply. It communicates with the target microcontroller over SPI interface.

The ADuM4154 has four high-speed channels. The first three channels, CLK, MI/SO, and MO/SI (the slash indicates the connection of the particular input and output channel across the isolator) are optimized for either low propagation delay in the B grade, or high noise immunity in the A grade.

SPI (Serial Peripheral Interface) communication is one of the most popular protocols for sending data between microcontrollers and different peripherals.

It is a synchronous protocol; the clock signal is provided by the controller.
