關於Raspberry Pi(樹莓派) Raspberry Pi是一款基於Linux系統的只有一張信用卡大小的電腦,如果將它連接到你的電視或是接上鍵盤,就像是一台小型個人電腦,它可以處理你在個人電腦上做的事,比如說試算表、文字編輯、遊戲等等,還能播放高畫質的視訊影片。你可以在PC Home 等賣場可以買到Raspberry Pi,價格會在1300 到 1600 台幣之間。

商品介紹:

樹莓派(英語:Raspberry Pi),是一款基於Linux系統的只有一張信用卡大小的單板機電腦。它由英國的樹莓派基金會所開發,目的是以低價硬體及自由軟體刺激在學校的基本的電腦科學教育。 [4][5][6][7][8]
樹莓派的生產是通過有生產許可的兩家公司:Element 14/Premier Farnell和RS Components。這兩家公司都在網上出售樹莓派。 [9]
樹莓派配備一枚700MHz博通出產的ARM架構BC​​M2835處理器,256MB內存(B型已升級到512MB內存),使用SD卡當作儲存媒體,且擁有一個Ethernet,兩個USB接口,以及HDMI(支持聲音輸出)和RCA端子輸出支援。 Raspberry Pi只有一張信用卡大小,體積大概是一個火柴盒大小,可以執行像雷神之鎚III競技場的遊戲和進行1080p影片的播放。操作系統採用開源的Linux系統,比如Debian、ArchLinux,自帶的Iceweasel、KOffice等軟體能夠滿足基本的網絡瀏覽,文字處理以及電腦學習的需要,分A,B兩種型號,其中售價分別是A型25美元,B型35美元。基金會從2012年2月29日開始接受B型的訂貨。 [10]
樹莓派基金會提供了基於ARM的Debian和Arch Linux的發行版供大眾下載。還計劃提供支持Python 作為主要編程語言[11][12], 支持BBC BASIC[13] , (通過RISC OS 映像或者Linux的”Brandy Basic”克隆)[14], C, 和Perl等編程語言.

Who wants pi? The Raspberry Pi has made quite a splash since it was first announced. The credit-card sized computer is capable of many of the things that your desktop PC does, like spreadsheets, word-processing and games. It also plays high-definition video. It can run several flavors of Linux and is being used to teach kids all over the world how to program.
The secret sauce that makes this computer so small and powerful is the Broadcom BCM2835, a System-on-Chip that contains an ARM1176JZFS with floating point, running at 700Mhz, and a Videocore 4 GPU. The GPU provides Open GL ES 2.0, hardware-accelerated OpenVG, and 1080p30 H.264 high-profile decode and is capable of 1Gpixel/s, 1.5Gtexel/s or 24 GFLOPs of general purpose compute. What’s that all mean? It means that if you plug the Raspberry Pi into your HDTV, you could watch BluRay quality video, using H.264 at 40MBits/s.
But wait, there’s more. The Model B also has a 10/100 Ethernet port so you can surf the web (or serve web pages) from right there on the Pi. The system volume lives on an SD card, so it’s easy to prepare, run and debug several different operating systems on the same hardware. Most Linux distributions for the Pi will happily live on a 2GB SD card but larger cards are supported.
The Model B’s two built-in USB ports provide enough connectivity for a mouse and keyboard, but if you want to add more you can use a USB hub. It is recommended that you use a powered hub so as not to overtax the on-board voltage regulator. Powering the Raspberry Pi is easy, just plug any USB power supply into the micro-USB port. There’s no power button so the Pi will begin to boot as soon as power is applied, to turn it off simply remove power.
On top of all that, the low-level peripherals on the Pi make it great for hardware hacking. The 0.1″ spaced GPIO header on the Pi gives you access to 8 GPIO, UART, I2C, SPI as well as 3.3 and 5V sources. Mating ribbon cables can be found in the related products below.
Note: The supply of Rasbperry Pi is incredibly limited. We do not expect to get very many at a time and even those shipments will be sporadic at best. We are ordering the maximum allowable, but it will still not cover all backorders.
