I always use USPS Priority Mail shipping from digikey and mouser and jameco, and with the order
I placed yesterday with digikey, the shipping is $4.91. Priority usually takes 2 days to the west
coast. Mouser is a little cheaper than digikey for small quantities, but only digikey had some other
parts I needed for this order.
I also ordered a few atmega32A chips to play with. From what I can tell, these have the same
pinout as 644/1284, but are essentially a 328 in DIP40, so you get a -UNO with 40-pins. Also
2/3 cheaper than the 644/1284. I don't know if there is a bootloader for the 32A, however.
I should have ordered some 644s too, just to play, but forgot.
