What is Raspberry Pi?

The Raspberry Pi may be a low price, credit-card sized pc that plugs into a pc monitor or TV, and uses a customary keyboard and mouse. it's a capable very little device that allows folks of all ages to explore computing, and to find out a way to program in languages like Scratch and Python. It’s capable of doing everything you’d expect a PC to try to to, from browsing the net and taking part in high-definition video, to creating spreadsheets, word-processing, and taking part in games.

What’s additional, the Raspberry Pi  has the flexibility to act with the surface world, and has been employed in a large array of digital maker comes, from music machines and parent detectors to weather stations and tweeting birdhouses with infra-red cameras. we wish to envision the Raspberry Pi being employed by children everywhere the globe to find out to program and perceive however computers work.

DESCRIPTION:

Didn't suppose the Raspberry Pi might get associatey better? you are certain  an enormous surprise! The Raspberry Pi two Model B is out and it's amazing! With an upgraded ARMv7 multicore processor, and a full G of RAM, this pocket pc has emotional from being a 'toy' to a true desktop PC!

The big upgrade may be a move from the BCM2835 (single core ARMv6) to BCM2836 (quad core ARMv7). The upgrade in processor typesmeans you'll see ~2x performance increase simply on processor-upgrade solely.  For code which will cash in of multiple-core processors, you'll expect 4x performance on the average and for very multi-thread-friendly code, up to 7.5x increase in speed!

That's not even taking under consideration the one Gig of RAM, which is able to greatly improve games and web-browser performance!

Best of all, the Pi two keeps a similar form, connectors and mounting holes because the Raspberry Pi B+. meaning that each one of your HATs and alternative plug-in daughterboards can work simply fine. ninety nine of cases and accessories are absolutely compatible with each versions

Please note: The processor has utterly modified on the new RaspberryPi two, rather than a ARM v6 core chip (arm6l) the BCM2836 has been upgraded to associate ARM v7 core that may be a way more powerful core. However, your existing Raspberry Pi South Dakota card pictures might not work as a result of the computer code and kernel should be recompiled/adapted for the new processor. If you have got a Raspberry Pi two, and you're making an attempt to upgrade your existing South Dakota card, you'll have to be compelled to upgrade your installation. To do that, log into your Pi one and at a console or terminal sort insudo apt-get upgrade to perform the upgrade procedure. you will need your Pi to get on the net to try to to this. Once upgraded, the cardboard can work on each Pi one and Pi two computers. If you have got any pre-compiled binaries that you just ar downloading, those might have change too, so as to require advantage of the speed increase. something wherever you have got access to ASCII text file is recompiled and need to work simply fine.


The Raspberry Pi is one in all the foremost versatile very little computers ever created, and it will do all types of things — like power robots, arcade machines, and now, high-ticket headphones. Pi two style has created a hybrid thermionic valve amp known as the 503HTA that towers atop the Raspberry Pi three or Pi three, permitting the Pi to drive stereo headphones between 32–300 ohms. It conjointly happens to be one in all the neatest-looking mods for the Raspberry Pi we have seen.

The 503HTA has already doubled its goal of $20,000 on Kickstarter and was absolutely funded in precisely 3 days. The creators ar still iterating with prototypes, however expect to deliver the amps to backers between Gregorian calendar month and Sept of this year with many tube choices out there. costs begin at $99, however as was common, early adopters pay at their own risk.

Three years once the launch of the primary Raspberry Pi, second generation hardware can prolong sale these days for a similar $35 worth whereas giving plenty additional power.

The noncommercial Raspberry Pi Foundation has sold-out four.5 million of the tiny computers. "It's many quite we tend to expected," Raspberry Pi creator Eben Upton told Ars.

The new "Raspberry Pi 2" has roughly a similar type issue because the $35 Model B+ from Gregorian calendar month 2014, that modified the looks by doubling the amount of USB ports to four, adding additional GPIO pins, and replacement the South Dakota card slot with a MicroSD one.

But the Model B+ had a similar processor because the original discharged in 2012. Raspberry Pi two earns its "2" with upgrades to the hardware and memory. The GPU is unchanged.

The new Pi contains a quad-core processor that runs at 900MHz, compared to a single-core hardware that ran at 700MHz within the 1st generation. it is also associate ARMv7 processor instead of associate ARMv6 processor, that restricted the code out there on the initial hardware.

Raspbian, a version of Debian compiled for the initial Pi’s processor, can build another look on Raspberry Pi two, however the ARMv7 processor ought to conjointly permit volunteers to bring Ubuntu and alternative OSes to the hardware.

The new Pi can have 1GB of RAM, double the previous version. you will be ready to realize links to distributors commerce the new Pi at the Raspberry Pi web site.

Raspberry Pi two may be a “Model B,” although there's no Model A nevertheless for the second generation hardware. Model A from the primary generation can still be out there.

“The current Raspberry Pi Model A+ is $20. we do not grasp nevertheless once which will be updated. we tend to suspect it'll get a RAM upgrade (256->512MB) before a processor upgrade. Keeping the value low is that the priority,” Raspberry Pi evangelist Matt Richardson told Ars.

Here is that the full list of specs for Raspberry Pi two Model B:

SoC: Broadcom BCM2836 (CPU, GPU, DSP, SDRAM)
CPU: 900 rate quad-core ARM Cortex A7 (ARMv7 instruction set)
GPU: Broadcom VideoCore IV @ 250 rate
More GPU info: OpenGL atomic number 99 two.0 (24 GFLOPS); 1080p30 MPEG-2 and VC-1 decoder (with license); ​1080p30 h.264/MPEG-4 AVC high-profile decoder and encoder
Memory: one GB (shared with GPU)
USB ports: four
Video input: 15-pin MIPI camera interface (CSI) connective

New Raspbian package pictures will be discharged these days. “They'll be compatible with either the Raspberry Pi or the Raspberry Pi two,” Richardson aforesaid. “People with South Dakota cards that have already got Raspbian on them are ready to update (only from their original Raspberry Pi) in order that their Raspberry Pi two will boot them. they're going to have to be compelled to use apt-get upgrade.” The one catch is that folks moving from the earliest Pi versions can ought to get the image onto a MicroSD card rather than a standard-sized South Dakota card.

Getting a Pi once they 1st came out was troublesome thanks to demand that so much outstripped provide. the availability chain has gotten higher, with the flexibility to make several tens of thousands per week, principally at a Sony mill in Wales, Upton told Ars. Upton expects quite one hundred,000 to be prepared for today's on sale date. they're going to in all probability ought to keep pumping them out, though; the muse remains commerce regarding two hundred,000 of the older Raspberry Pi computers a month.

The bigger hardware power and memory in Raspberry Pi two can sure enough fuel additional artistic comes. the initial Pi hardware was wont to build robots, arcade machines, media centers, a superior computing cluster, musical instruments, and plenty of alternative things. The Pi is additionally wont to teach kids a way to program.

Upton thinks the most recent Pi are quick enough to use as a basic PC. The second generation ought to supply drum sander net browsing and also the ability to run multiple programs quickly while not a lucid lag, he said. "We're hoping folks might use it as their main computer," he said. "We have folks here at the workplace United Nations agency use them as their second computer."

UPDATE: It seems each Ubuntu and Windows ten can run on the new Raspberry Pi.

"For the last six months we’ve been operating closely with Microsoft to bring the forthcoming Windows ten to Raspberry Pi two. Microsoft can have way more to share over the approaching months," Upton wrote these days. "The Raspberry Pi 2-compatible version of Windows ten are out there freed from charge to manufacturers."

The version of Ubuntu out there for the Pi is Snappy Ubuntu Core. This version targeted at developers and cloud deployments doesn't have a desktop interface...
