INTRODUCTION
The WM9081-6222-CO28-M-REV2 Customer Mini Board is compatible with the 6222-EV1 customer
evaluation board and together provide a complete hardware platform for evaluation of the WM9081.
The WM9081 Customer Mini Board can also be used independently and connected directly to a
processor board using flying wires or appropriate headers. This document will cover both, but
performance data will be based on the Wolfson system with 6222-EV1 main board. Configurations
covered are listed below:
•
