Received my first raspberry pi. I’ve been looking for a use for one of these for a while and finally found it. Come to find out there are three different types of pi’s on the market: Model A, Model B Rev 1 and Model B Rev 2. The Model A has no ethernet. To get connectivity, you must use a USB adaptor. Model B Rev 1 has wired ethernet whereas Rev 2 is the same, but with an extra 256mb RAM (512 total).
Raspberry Pi’s are now starting to show up on Amazon Prime, but the price is a bit higher than ordering from Sparkfun or Adafruit, but it will appeal the instant gratification crowd.
