5.1 Hardware Revision History and Known Issues

This user guide provides information about the latest available revision of the board. The following sections contain information about known issues, a revision history of older revisions, and how older revisions differ from the latest revision.

5.1.1 Identifying Product ID and Revision

There are two ways to find the revision and product identifier of the PIC18F16Q20 Curiosity Nano: Either by utilizing the MPLAB X IDE Kit Window or by looking at the sticker on the bottom of the PCB.

The Kit Window will pop up when connecting PIC18F16Q20 Curiosity Nano to a computer with MPLAB X IDE running. The first six digits of the serial number, listed under kit information, contain the product identifier and revision.

Tip: If closed, the Kit Window can be opened in MPLAB X IDE through the menu bar Window > Kit Window.

The same information is found on the sticker on the bottom side of the PCB. Most boards will have the identifier, revision, serial number, and manufacturing date printed in plain text as 02-nnnn\rr SN: mmmssssss [Manufacturing date], where “nnnn” is the identifier, “rr” is the revision, "mmm" is the manufacturer, and "ssssss" is the serial number.

The serial number string has the following format:

"nnnnnnrrmmmssssss"

n = product identifier

r = revision

m = manufacturer

s = serial number

The product identifier for PIC18F16Q20 Curiosity Nano is 02-00457.
