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
application
engineers
and
development engineers in evaluating the

sensor. LEDs are used to display the
output of the device. The design of the EV-
kit allows for flexibility, allowing the user to

mode to a PC, or use the small plug-in
boards in an application circuit.
