The LLC SPI click is a very useful Click board™ which can be utilized as the level converter for logic signals. The topology of this logic level conversion (LLC) circuit is perfectly suited for SPI communication between devices with unmatched voltages of their logic signals. Although there are some specialized integrated circuits on the market, sometimes it is more convenient to have a simple solution made of just a few passive elements and four MOSFETs.
It comes in the package which also includes the mikroSDK™ software and a library with all the functions. The Click board™ comes as a fully tested and approved prototype, making it a reliable device ready to use on the development board.
