How to assemble your case
Heatsink
The design is based around a Broadcom BCM2835 SoC, which includes an ARM1176JZF-S 700 MHz processor, VideoCore IV GPU, and 512 Megabytes of RAM. This revision 2.0 board features two mounting holes for easy installation, a built-in reset circuit, and can be powered via the USB data ports. The design does not include a built-in hard disk or solid-state drive, instead relying on an SD card for booting and long-term storage. This board is intended to run Linux kernel based operating systems.
The Raspberry Pi use Linux-kernel based operating systems. Debian GNU/Linux, Iceweasel, Calligra Suite and Python are planned to be bundled with the Raspberry Pi. The Raspberry Pi does not come with a real-time clock, so an OS must use a network time server, or ask the user for time information at boot time to get access to time and date info for file time and date stamping. However a real time clock (such as the DS1307) with battery backup can be easily added via the I2C interface.

How to set up the Raspberry Pi?
What’s the difference between Model A and Model B? Model A has 256MB RAM, one USB port and no Ethernet (network connection). Model B has 512MB RAM, 2 USB port and an Ethernet port. What are the dimensions of the Raspberry Pi? The Raspberry Pi measures 85.60mm x 56mm x 21mm, with a little overlap for the SD card and connectors which project over the edges. It weighs 45g. What SoC are you using? The SoC is a Broadcom BCM2835. This contains an ARM1176JZFS, with floating point, running at 700Mhz, and a Videocore 4 GPU. The GPU is capable of BluRay quality playback, using H.264 at 40MBits/s. It has a fast 3D core accessed using the supplied OpenGL ES2.0 and OpenVG libraries. Why did you select the ARM11? Cost and performance. How powerful is it? The GPU provides Open GL ES 2.0, hardware-accelerated OpenVG, and 1080p30 H.264 high-profile decode. The GPU is capable of 1Gpixel/s, 1.5Gtexel/s or 24 GFLOPs of general purpose compute and features a bunch of texture filtering and DMA infrastructure. That is, graphics capabilities are roughly equivalent to Xbox 1 level of performance. Overall real world performance is something like a 300MHz Pentium 2, only with much, much swankier graphics. Will it overclock? Most devices will run happily at 800MHz. In the latest Raspbian distro there is an option to change the overclocking options on first boot and any time afterwards by running “raspi-config” without voiding your warranty. It should be noted that these are experimental settings and not every board will be able to run stably at the highest setting. If you experience issues, try reducing the overclocking settings until stability is restored. Will it blend? Yes. We have conducted extensive virtual simulations. No Raspberry Pis were harmed in the testing. How does it boot? You have to boot from SD but a USB HD can “take over” after the initial boot. You cannot boot without an SD card. Where’s the on / off switch? To switch on: just plug it in! To switch off: remove power. Why is there no real time clock (RTC)? The expectation is that non-network connected units will have their clocks updated manually at startup. Adding an RTC is surprisingly expensive, once you’ve factored in batteries, area and componentry and would have pushed us above our target price. You can add one yourself using the GPIO pins if you’re after an interesting electronics project. Will you sell a self-assembly kit? No. It would be too expensive for us to provide kits alongside finished boards, which would mean introducing another step in manufacturing; and a kit would be impossible to hand solder. We use special equipment (robots!) to solder on the BGA package and other tiny components. Can I add extra memory? No. The RAM is a POP package on top of the SoC, so it’s not removable or swappable. What hardware documentation will be available? Broadcom don’t release a full datasheet for the BCM2835, which is the chip at the heart of the Raspberry Pi. We will release a datasheet for the SoC which will cover the hardware exposed on the Raspi board e.g. the GPIOs. We will also release a board schematic later on. But I want documentation for <hardware X>! Other documentation may be released in future but this will be at the Foundation’s discretion. To get the full SoC documentation you would need to sign an NDA with Broadcom, who make the chip and sell it to us. But you would also need to provide a business model and estimate of how many chips you are going to sell. Why doesn’t the Raspberry Pi include <insert name> piece of hardware or <insert name> sort of port? Our main function is a charitable one – we’re trying to build the cheapest possible computer that provides a certain basic level of functionality, and keeping the price low means we’ve had to make hard decisions about what hardware and interfaces to include. Can you test it to make sure that it is suitable for <X>? If you want to use it for something that we haven’t tested, and that it’s not intended for (i.e. anything but the educational work we’re planning for it), then that development work is up to you. How do I connect a mouse and keyboard? Model A has one USB port and Model B has 2. Beyond this, mice, keyboards, network adapters and external storage will all connect via a USB hub.
