1 Introduction
This user guide describes the operation of the IQS227-228BEV02 Evaluation Kit. The EV-Kit
consists of ten parts, the main board device, six separate plug-in module boards and three
overlays. Additional unprogrammed IC's (3 x IQS227B and 3 x IQS228B) are included. To
visualise raw data from the EV-Kit, the main board can be interfaced to any personal computer
with USB support, and IQS227 or IQS228 software GUI (Graphical User Interface). The purpose of
the IQS227-228BEV02 EV-Kit is to help application and development engineers in evaluating the
IQS227B and IQS228B proximity and touch sensor in self-capacitance mode.
