It allows the connection of most Cirrus Logic devices on mini-cards, as well as allowing connection of various application processor systems to provide a full evaluation platform. Audio system topology, clocking and power can all be controlled through the Lochnagar, allowing the device under test to be used in a variety of possible use cases.
