1 Introduction

This user manual describes the IQS127

evaluation kit. The EV-kit is made in two

parts, consisting of a mother board and

separate plug-in boards. It is developed to

facilitate

development engineers in evaluating the

IQS127 capacitive proximity and touch

output of the device. The design of the EV-

kit allows for flexibility, allowing the user to

use the IQS127 in direct mode, streaming

mode to a PC, or use the small plug-in

boards in an application circuit.
