1 Introduction
This user manual describes the operation of
the IQS213EV03 Evaluation Kit. The EV-Kit is
manufactured in five parts, consisting of the
mainboard device, and four separate swipe
plug-in module boards. To visualise raw data
from the EV-Kit, the main board can be
interfaced to any personal computer with USB
support, and IQS213 software GUI. The
purpose of the IQS213EV03 EV-Kit is to help
application and development engineers in
evaluating the IQS213 proximity, touch and
swipe sensor, in both self-capacitance and
projected capacitance modes.
2 Standalone/Datastreaming
EV-Kit
Figure 2.1 illustrates the evaluation kit
mainboard and a plug-in swipe module board.
Simply plug in the desired swipe module board
and turn on the power switch, as depicted in
Figure 2.2
Features included in the IQS213EV03:
Modular design: Connect one of the
supplied plug-in modules into the
mainboard, to evaluate and compare
swipe performance
Reference designs for IQS213 with user
proximity, touch and swipe detection ability
Four separate module boards to evaluate
2 or 3 channel swipe operation, in either
projected capacitance mode, or self-
capacitance mode

3 Standalone operation
3.1 Powering on the device
Figure 3.1 illustrates the top view of
IQS213EV03 EV-KIT
Ensure desired swipe module is plugged
in (swipe module are hot-swappable once
the device is powered on)
Power on the device by using the slide
switch as indicated in figure 3.1
Figure 3.1 IQS213EV03 after power on
(top view)
After the device is powered by means of the
On/Off slide switch, the system calibrates itself
and displays information by means of indicator
LEDs.
The power indicator LED lights up in green to
indicate the system is powered up. The
system automatically detects which swipe
module is plugged in and displays this
information as illustrated in Figure 3.1.
The Swipe Engine Mode is displayed in the
upper left corner by means of three indicator
LEDs (please see the IQS213 datasheets for
information on configuring the Swipe Engine
Mode).
3.2 Device operation
Slide over the SwipeSwitchTM from left to
right, or from right to left to bring the
device out of standby mode
The Swipe Active indicator will light up as
illustrated in Figure 3.2.
Figure 3.2 IQS213EV03 Swipe Active
Indicator
In active mode the device will indicate touch
detection on each corresponding channel by
means of the touch detection indicator LEDs
as illustrated in Figure 3.3.
Figure 3.3 Swipe Mode Active
The swipe direction will be indicated by the
swipe direction indicator LEDs as depicted in
Figure 3.3.
When the swipe is completed the
corresponding LED (left or right), will pulse
once and turn off again indicating a successful
swipe detection.

4 Datastreaming Operation
For operation in data streaming mode, it is
necessary to interface the IQS213EV03 EV-Kit
to a personal computer by means of a Mini-
USB cable. The IQS213 GUI software is used
to stream and visualize data from the
IQS213EV03 EV-Kit in real-time.
Figure 4.1 IQS213 Graphical User Interface
The IQS213 Software GUI is available from the Azoteq website at www.azoteq.com.
Install the IQS213 GUI software
Plug in the desired module into the Mainboard
Connect the Mainboard to a personal computer with Mini-USB cable
Run the IQS213 Software GUI and Click on “Start”
The GUI display is illustrated in Figure 3.3 where channel 3 shows a valid touch, and proximity is
detected on all other channels.
Important Note: The IQS213 GUI User Guide contains additional information and operating
instructions and is available for download at www.azoteq.com.
