Description
This user guide describes an evaluation kit and an extension board for
SIGFOX™ applications. The example application uses an Atmel
ATmega328P AVR® or SAMD20/D21 microcontroller to read out an
AT30TS75A temperature sensor using the built-in TWI connection and
controls the RF telegram transmission using the SIGFOX ATA8520E V2.3
transceiver device. This application requires a SIGFOX base station
infrastructure to capture the RF telegram and supply payload data at the
SIGFOX back end of the SIGFOX Cloud. For more information on operating
the SIGFOX network and SIGFOX Cloud, see http://www.sigfox.com
information.
The evaluation and development kit tool packs are available for download
from the Atmel website: http://www.atmel.com/devices/ATA8520E.aspx

1. Getting Started with the ATA8520-EK1-F Kit
Figure 1-1 shows the components which are included in the evaluation kit. The kit includes
• A single PCB ATAB0102A with
– An Atmel® ATA8520E SIGFOX™ transceiver device
– An Atmel ATmega328P AVR® microcontroller at 8MHz
– An AT30TS75A temperature sensor with TWI
• An 902MHz monopole antenna for connection to the RP-SMA connector
The kit requires an external power supply or battery for 3.0V to 3.3V at 300mA which is not included in
the kit.
Figure 1-1. ATA8520-EK1-F Kit Components
The 902Hz monopole antenna is connected to the RP-SMA connector of the PCB and the external power
supply or battery has to be connected to connector X1.
Caution: Ensure correct polarity at the connection to avoid damage to the equipment. The
PCB has no reverse polarity protection for the power supply connection.
The kit comes with preconfigured devices for starting the Flash application of the Atmel ATmega328P
once the power is applied. This application controls the RF telegram transmission and reads out the
temperature sensor at 15 min. intervals or when pressing the SW1 button. The red LED1 starts blinking
for about 2-3s, i.e. during telegram transmission. The device then enters power-down mode until a wakeup from the internal timer or a button press occurs.

Every fifth transmission is executed as an uplink/downlink request, i.e. it will first transmit the RF telegram
with sensor data and requests a payload data packet from the SIGFOX cloud via a base station. The
execution of these request will take about 40-50s.
The Atmel ATA8520E device includes the SIGFOX ID and PAC registration code (see label attached to
PCB) to register the kit with the user's account for the SIGFOX back end. The user has to open a
SIGFOX cloud account to access the back end. From this account the data payload transmitted from the
devices can be retrieved in various ways as described in the SIGFOX online help.
An Atmel debugger (Atmel JTAGICE3 or Atmel ICE), which can be connected to connector XISP1, is
required for application development. Please see the marker for pin1 to connect with the correct
orientation. The debugger can only be used if Atmel Studio 6 or 7 is installed in the front end. Atmel
Studio 6 or 7 can be downloaded from http://www.atmel.com with additional user instructions and tools.
The documentation for the kit components and for the software is included in the tool pack zip folder [7]
which can be downloaded from the Atmel website [5].
The kit and the boards are preprogrammed and temperature calibrated to operate at room temperature
(24°C). For operation with a wider temperature range a temperature calibration as described in
“ATAN0142 - ATA8520E Crystal Calibration” has to be applied.

2. Getting Started with the ATA8520-EK3-F Extension Board
The kit as shown in Figure 2-1 includes
• A single PCB ATAB0102A with
– An Atmel® ATA8520E SIGFOX™ transceiver device
– An AT30TS75A temperature sensor with TWI
• An 902MHz monopole antenna for connection to the RP-SMA connector
Figure 2-1. ATA8520-EK3-F Xplained Pro Extension Board
The kit requires an additional XplainedPro SAMD20 or SAMD21 development kit and a 3.0V power
supply with 300mA (connected to X1) as shown in Figure 2-2.

Figure 2-2. ATA8520-EK3-F Xplained Pro Extension Board with SAMD20 or SAMD21 Xplained Pro Kit
The 902MHz monopole antenna is connected to the RP-SMA connector of the PCB and the board is
powered by an external 3V supply.
The tool pack [7] includes an example application for the SAMD20 and SAMD21 Xplained Pro kit at 3V/
48MHz.
This application controls the RF telegram transmission and reads out the temperature sensor at 15minute intervals or when pressing the SW1 button. The red LED1 starts blinking for about 2-3s, i.e. during
telegram transmission. The device then runs in a main loop until an event from the internal timer or a
button press occurs.
Every fifth transmission is executed as an uplink/downlink request, i.e. it will first transmit the RF telegram
with sensor data and requests a payload data packet from the SIGFOX cloud via a base station. The
execution of these request will take about 40-50s.
The ATA8520E device includes the SIGFOX ID and PAC registration code (see label attached on the
PCB) to register the kit with the user's SIGFOX back-end account. The user has to open a SIGFOX cloud
account to access the back end. From this account the data payload transmitted from the devices can be
retrieved in various ways as described in the SIGFOX online help.
The Atmel debugger included in the development kits can be used for application development.
Application development and use of the debugger is only possible if Atmel Studio 6 or 7 is installed in the
front end. Atmel Studio 6 or 7 can be downloaded from http://www.atmel.com with additional user
instructions and tools. The documentation for the kit components and for the software is included in the
tool pack zip folder [7] which can be downloaded from http://www.atmel.com/devices/ATA8520E.aspx.
