Hardware and Document Revision History.
7.1 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.
7.1.1 Identifying Product ID and Revision
There are two ways to find the revision and product identifier of the Multi-Phase Power Board and its Adapters: The MPLAB X IDE Kit Window or the sticker on the bottom of the PCB.
The Kit Window appears in MPLAB X IDE when connecting a Curiosity Nano development board to the computer. An additional page for the MPPB and Adapters shows when the CNANO is plugged into the socket on the board.
The first nine digits of the serial number, listed under kit information, contain the product identifier and revision.
The same information is found on the sticker on the bottom side of the PCB. The data matrix code on the sticker contains a string with the product identifier, revision and serial number.
The product identifier and revision of the MPPB are printed in plain text as 02-00671/rr, where "rr" represents the revision. The serial number is printed on the following line.
The string in the data matrix code has the following format:
"nnnnnnnrrsssssssss"
n = product identifier
r = revision
s = serial number
7.1.2 Revision 3
Revision 3 removes all 5% resistors and replaces them with equivalent 1% alternatives:
| Resistor | Value |

| R104, R110, R505 | 1 kΩ |
| R120, R400, R402, R404, R406, R408, R409, R410, R411 | 150 kΩ |
| R100, R113, R116, R118, R305_CS1, R305_CS2 | 100Ω |
7.1.3 Revision 2
