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 a 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. The sticker on SAM R21
Xplained Pro shows the identifier and revision plain text as
A09-nnnn\rr
where
nnnn
is the identifier and
rr
is the
revision. A uniqly assigned MAC64 address in hex, FCC ID and IC id are also printed on the sticker. A serial
number string is embedded in the matrix-barcode.
The serial number string has the following format:
"nnnnrrssssssssss"
n = product identifier
r = revision
s = serial number
