Raspberry Pi Gets an A+ for Education

The Raspberry Pi was intended as a learning device. David Braben, previously known for Rollercoaster Tycoon and other video games, noticed that computer science education was lacking and he wanted to contribute to its advancement with a cheap, portable, and highly-programmable PC. Yesterday, the organization announced a new model, the Raspberry Pi A+, which is (theoretically) cheaper, smaller, and has a few better components. This announcement follows the release of the Raspberry Pi B+ from last July.


I say “theoretically cheaper” because, although the organization is touting a price reduction from $25 to $20 USD, that always depends on the reseller. MCM Electronics, one of the foundation's US-based distributors, is selling the A+ for its list price of $20 (plus an extra ~$10 in shipping, before tax). In the UK, however, the currency conversion works out to about $25 before VAT. That said, the UK is known to be expensive for electronics.

Whatever the price, the device is slightly improved. While it keeps the same, Broadcom BCM2835 SoC and RAM, the memory has been upgraded to a locking MicroSD card slot, the audio's power delivery has been improved to reduce noise, and the number of GPIO pins has been increased from 26 to 40. The latter enhancement will allow the Pi to interface with more, and different, sensors and motors for robotics and other embedded applications.

The Raspberry Pi A+ and B+ are both currently on backorder for $20 and $35, respectively, before a $10 shipping fee and any applicable taxes.

I must say, that unlike cake: pie is the foundation of everlasting relationships – like circumference and diameter! That, and cake always seems to end up in lies (yes, that horse is still twitchin’). While my personal favorite flavor is blueberry I might just become fond of Raspberry Pi in the near future. We originally reported on the organization dedicated to providing computing technology to the masses a few months ago when they showed off their prototype computer-in-a-usb-stick. More progress on the logistics as well as a firm specification on the PCB have occurred since then and it aligns nearly perfectly with original predictions.


That… doesn’t really look edible…

The original prediction was a $25 device 700 MHz device backed by 128MB of RAM and an OpenGL ES 2.0 1080p-capable GPU. While that is still true, a second model will be released for $35 with double the RAM and an extra USB port for peripheral connectivity due to the addition of the SMSC LAN9512 two-device USB hub. The alpha board is slightly larger than the final design due to the ports required for debugging purposes and contains an extra couple layers on the PCB that will not be present in the final version. It is still expected to ship within the next 9 months (12 from original post) with the target narrowed slightly to likely sometime in 2011.

Ultra-cheap PC for education: 25$ gets you a very smart USB stick.

In case you did not get enough solder for one day: you are in luck! David Braben, previously known for his work developing such games as Rollercoaster Tycoon, Thrillville, and Kinectimals, created an extremely low cost PC for educational use. His goal is ultimately to have computers like the one he created be accessible such that there would be functionally zero barriers to entry for students to pursue studying computing. A charity was created, the Raspberry Pi Foundation, under these beliefs to distribute this device hopefully sometime within the next 12 months.

Am I the only one who finds it weird that an affordable PC uses HDMI?

Given our demographic it would be blasphemous to not relay the specifications of the PC he created. The PC itself is slightly larger than a USB key in size and runs Ubuntu as its operating system though other distributions are likely possible. The processor is an ARM11 clocked at 700 MHz supported by 128MB of RAM and a GPU which supports OpenGL ES2.0 outputting at least 1080p resolutions. For connectivity it has USB port to attach to a keyboard and an HDMI port to attach to a monitor or flat screen TV. Storage is handled for by an SD card and other accessories are mountable such as the demonstrated 12 MP camera. While not explicitly listed on their site it appears as if connectivity is achieved wired via Ethernet through USB.
While this is obviously a low powered device its cost is only around 25$ and should be powerful enough to handle website interaction, scripting, and other educational applications. This PC and others like it should hopefully ensure that everyone has access to the internet and all of its educational, professional, and employment benefits.
