6. Hardware Revision History and Known Issues
6.1. Identifying Product ID and Revision
The revision and product identifier of Xplained Pro boards can be found in two ways; either 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 Kit's 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 product identifier for ATBTLC1000 Xplained Pro is A09-2528.
6.2. Revision 2
Revision 2 is the initially released revision.
ATBTLC1000 Xplained Pro revision 2 is partially incompatible with SAM L21 Xplained Pro extension
header EXT1, pin 10 (Chip Enable) is shared with the user button SW0 on the SAM L21 Xplained Pro. A
workaround for the incompatibility is to modify the kit by cutting a track in the PCB from pin 10, and
soldering a wire from a test point to pin 4, of the Xplained Pro extension header as shown in the image
below.
