We've first wrote about this tiny US$25 PC back in October last year, and it's still yet to go on sale. Still, we couldn't resist posting this board diagram of the ridiculously small Raspberry Pi.
Despite the fact the board is smaller than an iPhone (see some comparison photos here), it still includes USB 2.0 (there's a version with two USB ports), HDMI, Ethernet, audio RCA video, DSI and micro USB power connectors. You boot the machine from an SD card (Fedora is the recommended OS).
The designers claim the graphics capabilities are "roughly equivalent to Xbox 1 level". Overall performance is "something like a 300MHz Pentium 2." (click to enlarge).
The Raspberry Pi will come with either 128MB or 256MB RAM - not much, but it has enough grunt, say the manufacturers, to output HD video. It can reportedly also play some older 3D games, like Quake, but the main intention is to provide a dirt cheap system that can be plugged into TV for basic jobs like word processing and spreadsheets. The group behind it say they want kids to learn programming with it.
The FAQ also reveals other limitations, which are to be expected for a machine of this size and cost. You can't add extra RAM, and while you can connect to a DVI monitor using an adapter, VGA would be trickier.
There won't be a case at launch, but cases are promised. That's something we'll be interested to see.
