Getting Started with the ATA8520-EK1-E Kit

Figure 1-1 shows the components which are included in the evaluation kit. The kit includes
●
A single PCB ATAB0101A with
● An Atmel
● An Atmel ATmega328P AVR
● An AT30TS75A temperature sensor with TWI
●
An 868MHz monopole antenna for connection to the SMA connector
The kit requires an external power supply or battery for 3.0V to 3.3V at 50mA which is not included in the kit.
Figure 1-1. ATA8520-EK1-E Kit Components
The 868MHz monopole antenna is connected to the SMA connector of the PCB and the external power supply or battery has
to be connected to connector X1.
Ensure correct polarity at the connection to avoid damage to the equipment. The PCB has no reverse polarity
Caution:
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 one-hour intervals
or when pressing the SW1 button. The red LED1 starts blinking for about 7-8s, i.e. during telegram transmission. The device
then enters power-down mode until a wake-up 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 ATA8520D 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 is installed in the front end. Atmel Studio 6 can be downloaded from
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 - ATA8520D Crystal Calibration" has
to be applied. This is mandatory to comply with the CE certification for the kit and boards and is valid for a temperature range
of –20°C to +55°C.
