Identifying Product ID and Revision
The revision and product identifier of Curiosity Nano boards can be found in two ways; either through the MPLAB X
IDE or by looking at the sticker on the bottom of the PCB. By connecting a Curiosity Nano board to a computer with
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 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
