Raspberry Pi unboxing


by Nick Heath  |  April 25, 2012, 5:25am PDT 
The wait is over. After months of anticipation the $40 Raspberry Pi computer is in the hands of the public.
Deliveries of the first boards began last week and TechRepublic was lucky enough to get its hands on one.
This unboxing gallery explores the hardware of the board in detail – from the chipset through to its ports.
The packaging for the Pi is minimal, however take a closer look at the envelope and you’ll spot the telltale raspberry logo, a clue that it contains one of the most anticipated computers of 2012.
Anyone wanting to buy a Pi should register with distributors Premier Farnell or RS Components, although boards are currently sold out and there are reportedly more than 350,000 people on the waiting list to get one.

The Raspberry Pi is shipped wrapped inside an anti-static bag.
The Pi ships as the bare board – to get it up and running you’ll need to source an SD card for storage, HDMI or composite video leads to hook it up to a TV or monitor , a micro USB power lead and a USB mouse and keyboard.
Your first port of call should be the downloads section of the Raspberry Pi Foundation website, where you can download a Linux OS customised to run on the board. There are a variety of OSes available, including Debian and Fedora. The foundation recommends that new users of Linux download the customised version of Debian Squeeze from the site.



Here’s the board in all it’s glory. The first 10,000 boards to ship are bare but later Raspberry Pi computers will include a case.
Two versions of the board are being sold, the model B selling at $40 and the model A, which will be slightly cheaper when it goes on sale later this year. Unlike the model B the model A will not have a 10/100 Ethernet port and only has one USB port.


 The tiny board truly lives up to its description as being a credit card sized computer, no longer than a USB stick and easily big enough to fit into a pocket.

The chip contains an ARM 11 processor running at 700MHz and a Videocore 4 GPU, which can play Blu-ray quality video and render 3D graphics.

The device is powered via micro USB. The shipping notes recommend using a good quality power supply capable of providing at least 700mA at 5V. The Pi shouldn’t be powered by plugging it into another computer or USB hub, according to the documentation.



The board’s general purpose input/output pins, which can be used to connect additional circuitry to Pi and expand its capabilities.
The pins allow expansion boards to be added that work with motors, sensors and other peripherals - allowing the Pi to be used for a wide range of tasks, for instance controlling robots.

Here is the Pi ready for use. Everything needed to run the Pi and more is plugged in - the keyboard, mouse, SD card, Ethernet cable and micro USB jack.
