1 Hardware Revision History
Information about known issues, revision history of current and older revisions, and how older revisions differ from the latest revision.
1.1 Identifying Product ID and Revision
There are two ways to find the revision and product identifier of the Curiosity Nano Explorer: The MPLAB® X IDE Kit Window or the sticker on the bottom of the PCB.
The Kit Window will appear in MPLAB X IDE when connecting a Curiosity Nano development board to the computer. An additional page for the Curiosity Nano Explorer is shown when the CNANO is plugged into to 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 02-00630, revision, and serial number.
The product identifier and revision is also printed in plain text as 02-00630/rr, where "rr" represents the revision. The serial number is printed on the next line.
The string in the data matrix code has the following format:
"nnnnnnnrrsssssssss"
n = product identifier
r = revision
s = serial number
1.2 Revision 3
Revision 3 is the initially released board revision.
1.3 Revision 2
Revision 2 is an early adopters revision.
I2C PULL-UP A: 4.7 kΩ (R101 and R102)
I2C PULL-UP B: 4.7 kΩ (R505 and R506)
A 10 nF capacitor (C405) is mounted instead of a 10 kΩ resistor (R452).
