3 Introduction

The DA7322 Evaluation Board (EVB) has been designed to allow measurement and evaluation of

the DA7322 device. The EVB is supplied with a USB memory stick containing various documents

and software to allow you to control the DA7322.

The software is called Power Commander and uses a simple graphical user interface to allow you to

control the DA7322 via the USB port of a PC.

The EVB has a number of jumper links providing the flexibility to change the system configuration

and to allow the required measurements to be made.
