What’s a Raspberry Pi?
The Raspberry Pi is a credit-card sized computer that plugs into your TV and a keyboard. It’s a capable little PC which can be used for many of the things that your desktop PC does, like spreadsheets, word-processing and games. It also plays high-definition video. We want to see it being used by kids all over the world to learn programming.
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.
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.
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.
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
What display can I use?
There is composite and HDMI out on the board, so you can hook it up to an old analogue TV, to a digital TV or to a DVI monitor (using a cheap adapter for the DVI). There is no VGA support, but adaptors are available, although these are relatively expensive.
Why is there no VGA support?
The chip specifically supports HDMI. VGA is considered to be an end-of-life technology, so supporting it doesn’t fit with our plans at the moment.
Is there a GPU binary?
Yes. The GPU binary also contains the first stage bootloader.
Can I add a touchscreen?
We haven’t experimented with any touchscreens yet, but there’s no electronic reason why it shouldn’t work. There’s lots of discussion about this on the forums. The main issue people are encountering seems to be one of cost; touchscreens are very pricey!
What is the usable temperature range?
The Raspberry Pi is built from commercial chips which are qualified to different temperature ranges; the LAN9512 is specified by the manufacturers being qualified from 0°C to 70°C, while the AP is qualified from -40°C to 85°C. You may well find that the board will work outside those temperatures, but we’re not qualifying the board itself to these extremes.
Is sound over HDMI supported?
What about standard audio in and out?
There’s a standard 3.5mm jack for audio out. You can add any supported USB microphone for audio in.
What are the power requirements?
The device is powered by 5v micro USB.
Can I run power Raspberry Pi from batteries as well as from a wall socket?
Yes. The device should run off 4 x AA rechargeable cells, but there may be stability issues as the batteries lose their charge. Using 4 x AA Alkaline cells will result in 6v and it is therefore recommended to use a voltage regulator.
Is power over Ethernet (PoE) possible?
Not in the base device, but it’s been a very commonly requested feature, so we’re examining options for later releases.
What operating system (OS) does it use?
We recommend Debian as our default distribution. It’s straightforward to replace the root partition on the SD card with another ARM Linux distro if you want to use something else (there are several available on RASPBERRY downloads page). The OS is stored on the SD card.
Does it have an official programming language?
By default, we’ll be supporting Python as the educational language.
Any language which will compile for ARMv6 can be used with the Raspberry Pi, though; so you’re not limited to using Python.
Will it run WINE (or Windows, or other x86 software)?
What Linux distros will be supported at launch?
Fedora, Debian and ArchLinux will be supported from the start. We hope to see support from other distros later. (Because of issues with newer releases of Ubuntu and the ARM processor we are using, Ubuntu can’t commit to support Raspberry Pi at the moment.) You will be able to download distro images from us as soon as the Raspberry Pi is released, and we will also be selling pre-loaded SD cards shortly after release.
Will it run Android?
A version of android can be found in the forum. It is not presently stable enough for everyday use, however work is continuing on it.
Will it run?
In general, you need to look to see whether the program you want can be compiled for the ARMv6 architecture. In most cases the answer will be yes. Specific programs are discussed on our forum, so you might want to look there for an answer.
Will it run the new Windows 8 ARM version?
We are not partners with Microsoft, and their support would be required for porting Windows 8.
What happens if I brick the device?
You can restore the device by reflashing the SD card.
Does the device support networking? Is there Wi-Fi?
The Model B version of the device includes 10/100 wired Ethernet. There is no Ethernet on the Model A version (which we expect to be taken up mostly by the education market), but Wi-Fi will be available via a standard USB dongle.
Why no Gigabit Ethernet?
The Ethernet is driven via USB 2.0, so the upstream bandwidth would not support Gigabit.
Does the device have support for any form of netbooting or pxe?
No. However, it’s such a low power device that we expect it to be left on much of the time!
How do you connect more than two USB devices?
Use a hub to increase the number of ports. Some keyboards have hubs built in which would work well. It is recommended to use a powered hub.
