Identifying Product ID and Revision
The revision and product identifier of the PIC18F16Q40 Curiosity Nano board can be found in two ways: Either by
utilizing the MPLAB
®
X IDE Kit Window or by looking at the sticker on the bottom side of the PCB.
By connecting PIC18F16Q40 Curiosity Nano to a computer with 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 PIC18F16Q40 Curiosity Nano is A09
