6.1
Identifying Product ID and Revision
The revision and product identifier of Xplained Nano boards can be found in two ways; either through Atmel Studio/
Microchip MPLAB
®
X IDE or by looking at the sticker on the bottom side of the PCB.
By connecting an Xplained Nano board to a computer with Atmel Studio/Microchip MPLAB
®
X IDE 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.
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 ATtiny416 Xplained Nano is A09-2795.
6.2
Fuse masking
The ATtiny416 RSTPINCFG fuse is masked in the mEDBG firmware. The user is not allowed to disable UPDI (use
pin as GPIO or RESET), as it will lock the debugger out of the device.
6.3
