Hardware Revision History and Known Issues
This user guide is written to provide information about the latest available revision of the board. The following
sections contain information about known issues, a revision history of older revisions, and how older revisions differ
from the latest revision.
6.1
Identifying Product ID and Revision
There are two ways to find the revision and product identifier of the Xplained Pro boards: either through Atmel Studio/
MPLAB
®
X or by looking at the sticker on the bottom side of the PCB.
When an Xplained Pro MCU board is connected to a computer with Atmel Studio/MPLAB
®
X running, an information
window with the serial number is shown. The first six digits of the serial number contain the product identifier and
revision. Information about connected Xplained Pro extension boards is also shown in the window.
The same information can be found on the sticker on the bottom side of the PCB. Most kits have stickers that have
the identifier and revision printed 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 data matrix 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 product identifier for the ATtiny3217 Xplained Pro is A09-2835.
