Getting Started
Quick-start
Three steps to start exploring the Atmel Xplained Pro platform:
A.
Download and install Atmel Studio.
B.
Launch Atmel Studio.
C.
Connect Ethernet1 Xplained Pro to an Xplained Pro MCU board and connect a USB cable to DEBUG USB
port on the Xplained Pro MCU board.
Connecting Ethernet1 Xplained Pro to the Xplained Pro MCU Board
Atmel Ethernet1 Xplained Pro has been designed to be connected to the Xplained Pro header marked EXT1.
However it is compatible with all Xplained Pro EXT headers. Refer to the pin-out of your Xplained Pro MCU
board to find out which Xplained Pro EXT headers that can be used.
Once the Xplained Pro MCU board is powered the green power LED will be lit and Atmel Studio will auto detect
which Xplained Pro MCU- and extension board(s) that are connected. You will be presented with relevant
information like datasheets and kit documentation. You also have the option to launch Atmel Software
Framework (ASF) example applications for the combination of Xplained Pro MCU board and extensions
connected. The target device is programmed and debugged by the on-board Embedded Debugger. No external
programmer or debugger tool is needed.

Xplained Pro
Xplained Pro is an evaluation platform that provides the full Atmel microcontroller experience. The platform
consists of a series of Microcontroller (MCU) boards and extension boards that are integrated with Atmel Studio,
have Atmel Software Framework (ASF) drivers and demo code, support data streaming, and more.
Xplained Pro MCU boards support a wide range of Xplained Pro extension boards that are connected through a
set of standardized headers and connectors. Each extension board has an identification (ID) chip to uniquely
identify which extension boards are attached an Xplained Pro MCU board. This information is used to present
relevant user guides, application notes, datasheets, and example code through Atmel Studio. Available Xplained
Pro MCU and extension boards can be purchased in the Atmel Web Store.
Hardware Identification System
All Xplained Pro compatible extension boards have an Atmel ATSHA204 CryptoAuthentication™ chip mounted.
This chip contains information that identifies the extension with its name and some extra data. When an Xplained
Pro extension board is connected to an Xplained Pro MCU board the information is read and sent to Atmel
Studio. The Atmel Kits extension, installed with Atmel Studio, will give relevant information, code examples, and
links to relevant documents. Table 1-1 Xplained Pro ID Chip Content shows the data fields stored in the ID chip
with example content.

Standard Headers and Connectors
Xplained Pro Standard Extension Header
All Xplained Pro kits have one or more dual row, 20-pin, 100mil extension headers. Xplained Pro MCU boards
have male headers while Xplained Pro extensions have their female counterparts. Note that all pins are not
always connected. However, all the connected pins follow the defined pin-out described in Table 1-2 Standard
Layout of Xplained Pro Extension Header. The extension headers can be used to connect a wide variety of
Xplained Pro extensions to Xplained Pro MCU boards and to access the pins of the target MCU on Xplained Pro
MCU board directly.

Hardware Revision History and Known Issues
Identifying Product ID and Revision
The revision and product identifier of Xplained Pro boards can be found in two ways, through Atmel Studio or by
looking at the sticker on the bottom side of the PCB.
By connecting an Xplained Pro MCU board to a computer with Atmel Studio running, an information window will
pop up. The first six digits of the serial number, which is listed under kit details, contain the product identifier and
revision. Information about connected Xplained Pro extension boards will also appear in the Atmel Kits window.
The same information can be found on the sticker on the bottom side of the PCB. Most kits will print the identifier
and revision in plain text as A09-nnnn\rr where nnnn is the identifier and rr is the revision. Boards with limited
space have a sticker with only a QR-code which contains a serial number string.
The serial number string has the following format:
"nnnnrrssssssssss"
n = product identifier
r = revision
s = serial number
The kit identifier for Ethernet1 Xplained Pro is 2258.
Revision 1
Revision 1 of Ethernet1 Xplained Pro is the initial released version. There are no known issues.
