Beschreibung

This document describes the characteristic and operation of the Active Semi ACT2861EVK1-201evaluation kit(EVK). It provides setup and operation instructions, schematic, layout, BOM, and test data. This EVKdemonstrates the ACT2861QI201 CMI version of the IC. Other ACT2861QIxxx options can be evaluated onthis EVK by replacing the IC and any other necessary components.
