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
The revision and product identifier of the AVR-IoT Wx boards can be found in two ways: Either by utilizing the Atmel
Studio/MPLAB X IDE Kit Window or by looking at the sticker on the bottom side of the PCB.
By connecting an AVR-IoT Wx to a computer with Atmel Studio/MPLAB X IDE running, the Kit Window will pop up.
The first six digits of the serial number, which is listed under kit information, contain the product identifier and revision.
Tip:
The Kit Window can be opened in MPLAB
®
X IDE through the menu bar
Window > Kit Window
.
The same information can be found on the sticker on the bottom side of the PCB. Most boards will 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, containing the product identifier, revision, and serial
number.
The serial number string has the following format:
"nnnnrrssssssssss"
n = product identifier
r = revision
s = serial number
The product identifier for AVR-IoT WG is A09-3203.
The product identifier for AVR-IoT WA is A09-3349.
