1 Introduction
This user manual describes the operation of
the IQS232/43EV02 Evaluation Kit. The EV-
Kit is manufactured in three parts, consisting of
a
mainboard, and three separate plug-in
module boards. To adjust IC OTP settings, the
main board can be interfaced to any personal
computer with the Azoteq Configuration Tool
(CTxxx), and making the adjustments by
means of theUSBProg software. The purpose
of the IQS232/43EV02 EV-Kit is to help
application and development engineers
in
evaluating the IQS232 and IQS243 proximity
and touch sensors.
2 EV-Kit Mainboard
Figure 2.1 illustrates the evaluation kit
mainboard and the three supplied controller
modules. 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. Features included in the EV-Kit
mainboard:
Modular design: Connect one of the
supplied IC modules into the mainboard,
or
wire into a prototype for rapid
prototyping
Reference designs for IQS232 and
IQS243 with user proximity & touch
detection ability
LEDs to indicate
proximity AND contact to
the buttons for IQS232

Figure 2.2 illustrates the bottom view of the
EV-Kit mainboard.The EV-Kit is powered by
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
provided
on
the
mainboard.
