ATA8520-EK1-E Standalone Kit
The Atmel® ATA8520-EK1-E evaluation kit is for demonstrating Atmel's RF SIGFOX com-
pliant ATA8520D device and includes a
●Single PCBTAB0101A-V3.0 (S8S8520) with
●Atmel ATA8520D SIGFOX transceiver device
●Atmel ATmega328P AVR® microcontroller at 8MHz
●Atmel AT30TS75A temperature sensor with TWI
●868MHz monopole antenna to be connected to the SMA connector

The devices are preprogrammed, i.e.
●The Atmel® ATA8520D device is preprogrammed with the SIGFOX ID and PAC registration code (see label attached
on the PCB) to register the kit within the user's SIGFOX back-end account. (The user has to open an account for the
SIGFOX cloud to have access to the back end. For more information, see http://www.sigfox.com.)
●The Atmel ATmega328P includes a Flash application to read out the temperature sensor and to control transmission
within the SIGFOX network. This requires a SIGFOX base station to be in range to capture the RF telegram.
Not included in the kit is a battery or external power supply for 3.0V to 3.3V at 50mA. This power supply has to be connected
to connector X1. (Please observe correct polarity! There is no protection against incorrect polarity!)
The SIGFOX data transmission is repeated at one-hour intervals with the temperature and battery voltage value transmitted
as long as the kit is powered. In addition a transmission can be triggered by pressing the SW1 button. The red LED flashes
for about 7-8s during transmission of the SIGFOX telegram.
A tool pack for this kit is available for download from http://www.atmel.com/devices/ATA8520.aspx and includes
●The ATAN0054 kit quick start guide and ATAN0104 user guide
●The schematic, layout and Gerber data for the ATAB0101A PCB
●The source code for the ATmega328P as an Atmel Studio 6 project
An AVR® debugger (JTAGICE3 or Atmel ICE) and Atmel Studio 6 are required for application development.
The kit is 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 - ATA8520D Crystal Calibration” has to be applied.
This is mandatory to comply with the CE certification for this kit and is valid for a temperature range of –20°C to +55°C.

1. ATA8520-EK2-E and -EK3-E
The Atmel® ATA8520-EK2-E and -EK3-E extension boards are intended for Flash application development for Atmel's RF
SIGFOX compliant ATA8520D device and are available in two versions
1. An ATA8520-EK2-E Xplained Mini extension board for Atmel’s Xplained Mini or Arduino UNO kit
2. An ATA8520-EK3-E Xplained Pro extension board for the Atmel’s Xplained Pro kits
Both extension boards do not include the development kits. This has to be ordered separately.
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 - ATA8520D Crystal Calibration” has to be
applied. This is mandatory to comply with the CE certification for these boards and is valid for a temperature range of –20°C
to +55°C.
1.1 ATA8520-EK2-E Xplained Mini Extension Board
The ATA8520-EK2-E Xplained Mini extension board is a board for Atmel’s Xplained Mini or the Arduino UNO development
kit. This kit includes
●A single PCB ATAB0101A-V3.0 (U8S8520) with
●ATA8520D SIGFOX transceiver device
●AT30TS75A temperature sensor with TWI
●Four shield connectors and SMA connector
●868MHz monopole antenna to be connected to the SMA connector
●4 connectors for Xplained Mini kit
The kit does not include the Xplained Mini or Arduino UNO development kit and the four connectors for the Xplained Mini to
connect to the ATAB0101A PCB. These must be ordered separately. Figure 1-1 shows the ATAB0101A PCB with attached
external antenna.
Figure 1-1. ATA8520-EK2-E Xplained Mini Shield
The Atmel ATA8520D device is preprogrammed with the SIGFOX ID and PAC registration code (see label attached on the
PCB) to register the kit within the user's SIGFOX back-end account. (The user has to open an account for the SIGFOX cloud
to access the back end. For more information, see http://www.sigfox.com.)
A sample application is supplied with the tool pack zip folder for the Xplained Mini and Arduino UNO. This application reads
the temperature sensor and controls transmission within the SIGFOX network. This requires a SIGFOX base station to be in
range to capture the RF telegram.
A tool pack zip folder for this kit is available for download from http://www.atmel.com/devices/ATA8520.aspx and includes
●The ATAN0054 kit quick start guide and ATAN0104 user guide
●The schematic, layout and Gerber data for the ATAB0101A PCB
●The source code for the Xplained Mini with ATmega328P as an Atmel Studio6 project
●An Arduino UNO sketch with ATA8520D library for the Arduino IDE

Atmel Studio 6 must be installed before connecting the Xplained Mini kit. See additional instructions provided with the
Xplained Mini kit. No additional debugger is required because this is integrated on the Xplained Mini. The Xplained Mini also
provides a virtual COM port which is used by the Flash application together with a PC terminal application (TeraTerm,
HTerm, etc.) to print or read ASCII messages. Use the following COM port settings for communication: 38.4kBaud, 8bit, 1
stop, no parity.
Instead of the Xplained Mini kit, an Arduino UNO kit can be used together with the Arduino IDE for application development.
The ATA8520D library is included together with a sample sketch application for this environment.
1.2 ATA8520-EK3-E Xplained Pro Extension Board
The ATA8520-EK3-E Xplained Pro extension is an extension board for Atmel®’s Xplained Pro development kits. Included in
this kit are a
●Single PCB ATAB0101A-V3.0 (P8S8520) with
●ATA8520D SIGFOX transceiver device
●AT30TS75A temperature sensor with TWI
●Xplained Pro and SMA connector
●868MHz monopole antenna to be connected to the SMA connector
The Xplained Pro development kit is not included and must be ordered separately. Figure 1-2 shows the ATAB0101A PCB
attached to a SAMD21 Xplained Pro kit.

The Atmel ATA8520D device is preprogrammed with the SIGFOX ID and PAC registration code (see label attached on the
PCB) to register the kit within the user's SIGFOX back-end account.
