These boards come from a numbered, very limited edition of only ten units. We'll be auctioning two a day for the next five days, starting with the unit numbered #10, counting down to #01. They will be sent to the auction winners with a numbered certificate of authenticity, stating that the board is one of the first ten ever built. We'll also throw in a USB power supply and an SD card with a pre-release Linux distribution on it.
You are bidding on a development board, which does not attract a warranty or support. All the money raised from this auction will be put straight back into the Raspberry Pi Foundation, and will be used to fund its charitable activities.
