7.1.1 Identifying Product ID and Revision
There are two ways to identify the revision and product identifier of the MCP2222 Breakout Board:
Check the sticker on the bottom side of the PCB.
Read the information from the on-board USB bridge. This method requires familiarity with USB devices or the use of a dedicated application to read USB device information.
The first nine digits of the serial number contain the product identifier and revision information. The data matrix code on the sticker contains a string that includes the product identifier, revision, and serial number.
The product identifier and revision are printed in plain text on the MCP2222 Breakout board as 04-12560 rr, where “rr” represents the revision.
The string in the data matrix code has the following format:
"nn- nnnnn rr"
n = product identifier
r = revision
