Does anyone know where to get a schematic for the ATMEGA-A1 XPLAINED reference design? I believe the board is Rev 7, recently purchased from Digi-Key. Thanks
It should be part of AVR1907 app note i.e. the Xplain board.
If there is another board called 'Xplained', then you will need to look elsewhere.
Thanks for your speedy reply.
Apparently there are two different XMega reference boards, one called XPLAIN & the other XPLAINED. The one I have is clearly marked in the silkscreen as "ATMEGA-A1 XPLAINED". I have seen photos of another board which is simply marked "XPLAIN". Lots of room for customer confusion here!
I bought this from DigiKey and they offer two app notes on their associated product page: AVR1907 (as you referred to) and AVR1924. The 1924 seems to be the app note which is specifically about the XPLAINED board I have.
In AVR1924 is a link which purports to point to the schematic, BOM, PCB files, etc. However, it just leads to a morass of general purpose XPLAIN/ED hype on the Atmel website.
I was hoping one of the AVR Freaks would have already solved this puzzle and knew where exactly to go to get it.
By the way, the package in which I received the XPLAINED board "explained" how there was no CD included with the board to "protect the environment". I guess they were afraid a baby dolphin would stick its nose in the CD hole and suffocate. If they would only pay as much attention to the value of their customers' time! I have already spent several frustrating hours looking for this schematic.
The A1-Xplained schematic can be found in the archive file for AVR1924 ( http://atmel.com/dyn/products/to... )

Thanks for clarifying this for me! I did indeed find the zip file under the "Software" icon that contains the schematic pdf and more that I've been looking for.
I made the rash assumption that "Software" meant software associated with the AVR1924 app note - like code examples, AVR demo projects and the like. Silly me, now I know that "software" can also mean "hardware" (at least in the Atmel World).
The Romans had an expression which sort of fits this situation. Actually, the Romans inherited the expression from the Egyptians, who, it is rumored, actually stole it from the Phoenecians.
I can't quote it to you in Latin, or Old Kingdom Egyptian, or archaic Phoenecian, but I can say it in plain old English:
"Say what you mean, and mean what you say."
Perhaps, as good advice to the Atmel web designers today, as it was to the Egyptian heiroglyphic carvers.
Thanks Again, now I can get back to being a EE....
