Introduction

This user guide describes the operation of the IQS72xxxEV01 Evaluation Kit. The EV-Kit consists of

6 parts:

•IQS7211A Stamp + 5 x IC’s

•IQS7222A Stamp + 5 x IC’s

•IQS7222B Stamp + 5 x IC’s

•IQS7222C Stamp + 5 x IC’s

•IQS7228A Stamp + 5 x IC’s

•Connector board

To visualise raw data from the EV-Kit, the stamp board can be interfaced to any personal computer

with USB support, and the relevant IQS72xxx software Graphical User Interface (GUI). The purpose

of the IQS72xxxEV01 EV-Kit is to help application- and development engineers to a range of

Azoteq’s IC’s.
