The revision and product identifier of the PIC18F47K42 Curiosity Nano can be found in two ways; either through Microchip MPLAB® X IDE or by looking at the sticker on the bottom side of the PCB.
By connecting a PIC18F47K42 Curiosity Nano to a computer with 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. The boards with limited space have a sticker with only a QR code, containing the product identifier, revision and the serial number.
The serial number string has the following format:
"nnnnrrssssssssss"
n = product identifier
r = revision
s = serial number
The product identifier for PIC18F47K42 Curiosity Nano is A09-3244.
