LLC-SPI Click Board

The LLC SPI Click Board™ is a very useful Click Board™ that 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 specialised 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.
