Cirrus Logic’s 6271-EV2 ('Lochnagar 2') is an evaluation and development platform with support for interchangeable daughtercards. It is designed to provide a variety of audio inputs and outputs to Cirrus Logic devices and to allow for configuring and programming them in a variety of possible use cases.

The 6271-EV2 (‘Lochnagar 2’) can stream up to 16 channels of USB audio from the PC. It has software-controlled signal routing options, a wide range of analogue and digital audio input and outputs, and a built-in current monitor feature that allows the power consumption of Cirrus Logic devices to be measured without any external equipment.
