1 Introduction
This user manual describes the operation of
the IQS259EV02 Evaluation Kit. The EV-Kit is
manufactured in two parts, consisting of a
mainboard, and a separate plug-in module
board. The purpose of the IQS259EV02 EV-
Kit is to facilitate application and development
engineers in evaluating the IQS259 projected
capacitive proximity and touch sensor.
2 EV-Kit Mainboard
Figure 2.1 illustrates
mainboard and the supplied controller module.
The mainboard supplies power and other
functions to the controller module boards and
is easily operated. Simply plug in the desired
module board into the mainboard and turn on
the mainboard by means of the on/off slide
switch (if using battery or external power).
Features included in the EV-Kit mainboard:
Modular design: Connect the supplied IC
module into the mainboard, or wire into a
prototype for rapid prototyping
Reference design for IQS259 with user
proximity & touch detection ability
GUI interface indicates proximity AND
contact to the buttons

the Azoteq CTxxx or optionally two 3V coin cell
batteries in series, which is regulated to 3.3V
and supplied to the module board. The EV-Kit
mainboard can also draw power from a USB
source by means of the mini-USB connector
