🦄 Duemilanove: Historical Artifact or Unicorn?

I found this sweet baby on eBay… I dropped an ATMEGA328 in it and robbed a lowly UNO for it’s plastic bottom protector.

The above Duemilanove (2009 in Italian) was part of a limited production run.

From a geological layer not Cambrian but pretty far down in my goodie box for reference.



Definitely genuine. Purchased sometime in 2009.

It’s a better board than Uno. Use it. If you like, you can burn the Uno bootloader on the ATmega328P and have slightly faster uploads. I believe the 4 pads below the FTDI chip can be used to turn the FTDI into a bit-banging ISP programmer.

And also 1.5 kB more precious flash memory for your sketch programs (the Uno's Optiboot bootloader fits in a 0.5 kB boot section, while the traditional "ATmegaBOOT" bootloader requires a 2 kB boot section)!

I am pretty sure that is an old school date code made the week of Christmas in 2008.

That one is old enough to move out and get it’s own place. :smiley:

I believe you are right!
I have an even older NG embedded in a restaurant's meat dry aging room that I can't photograph. Sparkfun was a US distributor back then and they also made their own labeled Pro version with no FTDI chip.

It appears to have a real crystal for the ATmega328P chip instead of a resonator.

It's in beautiful condition. Nice find!

I have the Ninja protecting it…

Ugh. Don't remind me. I noticed that it's quite possible that some of the people needing help on the forum weren't even born when I started playing with Arduino...

Mine has the blue board like @EmilyJane . Even the same date code.

One thing to be aware of is that the onboard LED on pin 13 is not buffered. This can be a problem for some I/O cases.

I was doing some more research on Duemilanove. And, I found a document referring to the Duemilanove as "A000001". I never realized it was part number #1.
