1. ATA8520-EK1-F Standalone Kit

The Atmel® ATA8520-EK1-F evaluation kit is for demonstrating Atmel's RF SIGFOX™ compliant

ATA8520E device and includes a

•Single PCB ATAB0102A-V1.0 with

–Atmel ATA8520E SIGFOX transceiver device

–Atmel ATmega328P AVR® microcontroller at 8MHz

–Atmel AT30TS75A temperature sensor with TWI

•902MHz monopole antenna to be connected to the RP-SMA connector

Figure 1-1. Atmel ATA8520-EK1-F

The devices are preprogrammed, i.e.

•The Atmel ATA8520E 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 300mA. 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 15 minutes 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 2-3s during transmission of the SIGFOX

telegram.

[APPLICATION NOTE]

Atmel-9413B-ATAN0157_Application Note-06/2016

A tool pack for this kit is available for download from http://www.atmel.com/devices/ATA8520E.aspx and

includes

•The ATAN0157 kit quick start guide and ATAN0156 user guide

•The schematic, layout and Gerber data for the ATAB0102A 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.

1.1. Compliance Statements

The Atmel® ATA8520-EK1-F kit is designed to be used for standalone operation and not to be integrated

into systems and devices.

This kit complies with Part 15 of the FCC Rules and with Industry Canada licence-exempt RSS

standard(s). Operation is subject to the following two conditions:

1. this device may not cause harmful interference, and

2. this device must accept any interference received, including interference that may cause undesired

operation.

Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts

de licence. L'exploitation est autorisée aux deux conditions suivantes:

1. l'appareil ne doit pas produire de brouillage, et

2. l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible

d'en compromettre le fonctionnement.

Changes or modifications made to this equipment not expressly approved by Atmel may void the FCC

authorization to operate this equipment.

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant

to Part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful

interference in a residential installation. This equipment generates, uses and can radiate radio frequency

energy and, if not installed and used in accordance with the instructions, may cause harmful interference

to radio communications. However, there is no guarantee that interference will not occur in a particular

installation. If this equipment does cause harmful interference to radio or television reception, which can

be determined by turning the equipment off and on, the user is encouraged to try to correct the

interference by one or more of the following measures:

•Reorient or relocate the receiving antenna.

•Increase the separation between the equipment and receiver.

•Connect the equipment into an outlet on a circuit different from that to which the receiver is

connected.

•Consult the dealer or an experienced radio/TV technician for help.

This equipment complies with FCC and IC radiation exposure limits set forth for an uncontrolled

environment. This equipment should be installed and operated with minimum distance of 20cm between

the radiator and your body.

This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.

[APPLICATION NOTE]

Atmel-9413B-ATAN0157_Application Note-06/2016

Cet équipement est conforme aux limites d'exposition aux rayonnements IC établies pour un

environnement non contrôlé. Cet équipement doit être installé et utilisé avec un minimum de 20cm de

distance entre la source de rayonnement et votre corps.

Ce transmetteur ne doit pas etre place au meme endroit ou utilise simultanement avec un autre

transmetteur ou antenne.

2. ATA8520-EK3-F Xplained Pro Extension Board

The ATA8520-EK3-F Xplained Pro extension is an extension board for Atmel®’s Xplained Pro

development kits. Included in this kit are a

•Single PCB ATAB0102A-V1.0 with

–Atmel ATA8520E SIGFOX transceiver device

–Atmel AT30TS75A temperature sensor with TWI

–Xplained Pro and RP-SMA connector

•902MHz monopole antenna to be connected to the RP-SMA connector

The Xplained Pro development kit is not included and must be ordered separately. Figure 2-1 shows the

ATAB0102A PCB attached to a SAMD21 Xplained Pro kit.

A separate power supply with 3V/300mA must be connected to connector X1 to supply the RF module.

This power supply must be connected before starting the software application in the Xplained Pro kit.

Figure 2-1. ATA8520-EK3-F Xplained Pro Extension

The Atmel ATA8520E 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.

A sample application is supplied with the tool pack zip folder for the SAMD21 Xplained Pro. 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/

ATA8520E.aspx and includes

•The Atmel ATAN0157 kit quick start guide and the Atmel ATAN0156 user guide

•The schematic, layout and Gerber data for the ATAB0102A PCB

[APPLICATION NOTE]

Atmel-9413B-ATAN0157_Application Note-06/2016

•The source code for the Xplained Pro with Atmel SAMD21 as an Atmel Studio6 project

Atmel Studio 6 must be installed before connecting the Xplained Pro kit. See additional instructions

provided with the Xplained Pro kit. No additional debugger is required because this is integrated on the

Xplained Pro. The Xplained Pro 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.

The board 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.
