Features

User guide for the evaluation kit ATA8520-EK1-F and extension board
ATA8520-EK3-F (for the US market)

This kit demonstrates a Flash application with the

ATA8520-EK1-F evaluation kit: 
with the Atmel

®

 SIGFOX

 ATA8520E V2.3 transceiver device

and an Atmel ATmega328P AVR

®

 microcontroller with

AT30TS75A temperature sensor as a battery-powered kit for
standalone operation

ATA8520-EK3-F extension board: 
Includes Atmel SIGFOX ATA8520E V2.3 transceiver device with
an AT30TS75A temperature monitoring device. An additional
MCU application development kit, i.e., XplainedPro SAMD20 or
SAMD21 and 3V power-supply is required.

The PCB can be modified to be used together with an Atmel Xplained
mini or Arduino UNO kit

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
