5. Hardware Revision History and Known Issues
This user guide provides the latest available revision of the kit. This section contains information about known issues,
a revision history of older revisions, and how older revisions differ from the latest revision.
5.1 Identifying Product ID and Revision
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.
5.2 Revision 2
Revision 2 adds the Target Power strap and staggered the holes along the edge of the PCB for convenient use of pin
headers without soldering.
5.3 Revision 1
Revision 1 is the initially released revision with limited distribution.
The holes along the edge of revision 1 are not staggered as described in 4.1.2 Using Pin Headers , and requires that
any pin headers must be soldered into the board for use.
Revision 1 does not have the Target Power strap described in 3.4 Target Current Measurement , instead current can
be measured across the Power Supply strap as described in 3.5 Disconnecting the On-Board Debugger .
