That's right, $5.51 each what was closer to $8 not so long ago.
To be exact, Mouser charged me that for ATmega1284P-PU chips.
So if you've had a feeling like building a duino with 16K RAM, 2 serial and 4 ports of 8 open IO pins, it got cheaper.
This is the biggest, baddest AVR that comes in breadboard-friendly pins form, the rest are surface mount.
