1. What it the Username and Password for the Raspberry Pi?

The default username for most distro is “pi” (without any quote marks) and the default password is “raspberry” (again, do not include the quote marks). If that does not work, check the information about your specific disto on the

2. Why does nothing happen when I type in my password, did my Raspberry Pi freeze?

To protect your information, Linux does not display anything when typing in passwords in the bash prompt or the terminal. As long as you were able to see the username being typed in, your keyboard is working correctly.

3. What is the difference between Model A and Model B?

The Model A has 256MB RAM, one USB port and no Ethernet (network connection). The Model B has 512MB RAM, 2 USB ports and an Ethernet port.

4. How do I connect a mouse and keyboard?

The Model A has one USB port and Model B has 2 that can be used to connect most USB 2.0 devices. Additional USB devices such as mice, keyboards, network adapters and external storage will all connect via a USB hub.

5. Where is the on/off switch?

To switch off: If you are in the graphical environment, either exit to the bash prompt or open the terminal. From the bash prompt or terminal shut down the Raspberry Pi by entering “sudo halt -h” (without the quote marks) . Wait until all the LEDs except the power LED are off, then wait an additional second to make sure the SD card can finish its wear leveling tasks and write actions. You can now safely unplug the Raspberry Pi. Failure to properly shut the Raspberry Pi may corrupt your SD card, and you will have to re-image it.

6. Who or what is NOOBs?

NOOBs stands for New Out of Box Software. It is our recommended installation method. It allows you to install the distro of your choice even if you have little to no computing or Linux experience. A noob is someone who is inexperienced: the title should be worn with pride. After all; the only people who were never a noob at some point were those who never bothered to learn anything at all!

7. When will the next model of the Raspberry Pi be released?

As of the end of 2013, there are no immediate plans for the next model; possibly a new model will be released in 2-3 years, but this is not a firm time frame. A new model would inherently undo much of the community work that has been done to date on the Raspberry Pi, which would be counter-productive to our educational aims. We concentrate our engineering effort on making the software that runs on the Raspberry Pi faster and better all the time – which is why you should always be running the most recent firmware.

Minor hardware revisions, such as bringing out i2s on the Model B rev. 2 board, will occur on an as needed basis and have no set timeframe or schedule.

8. What are the dimensions of the Raspberry Pi?

The Raspberry Pi measures 85.60mm x 56mm x 21mm (or roughly 3.37″ x 2.21″ x 0.83″), with a little overlap for the SD card and connectors which project over the edges. It weighs 45g.

9. What hardware documentation is available?

All available documentation on the SoC, GPIO pins, and LAN9512 is available on our Tech documentation page

10. 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.
