Opções de compra do Raspberry PI


Primeiramente gostaria de salientar que não sou o autor principal do conteúdo deste artigo. A minha intenção é de mostrar o que outros autores tem realizado (referenciando links para o conteúdo original) neste blog até como um guia pessoal para uso próprio e ainda compartilhar minhas anotações e pequenas modificações que realizo no conteúdo, desejando que possa ajudar mais alguém em algum lugar.
First and foremost, I take no credit for any of this post’s content. I am really just taking what others have done (which I have links to bellow) and am putting it on my blog for a personal reference and hopefully the small changes that I made to their guides will help someone somewhere.

New Original Raspberry Pi 2 (900Mhz Quad Core ARM Cortex A7 1GB RAM)

Manufactured by element 14

The Raspberry Pi 2 Model B is the second generation Raspberry Pi. It replaced the original Raspberry Pi 1 Model B+.

Features

Compared to the Raspberry Pi Model B+ the Raspberry Pi 2 Model B is:
  • 6 x faster!- That’s faster gaming, faster computing, and faster programming.  
  • It features a new generation ARMv7 quad core processor.   
  • It has more memory- 1 GB RAM vs 512 MB (it has doubled!)- this means that you can run more applications simultaneously without compromising processing speed!
  • Has the same form fit as the Raspberry Pi Model B+ which means all of the accessories for the B+ are compatible with the Raspberry Pi 2 Model B! 
  • Is backward compatible with most Raspberry Pi Model B+ projects.

Like the (Pi 1) Model B+, it also has:

  • 4 USB ports
  • 40 GPIO pins
  • Full HDMI port
  • Ethernet port
  • Combined 3.5mm audio jack and composite video
  • Camera interface (CSI)
  • Display interface (DSI)
  • Micro SD card slot
  • VideoCore IV 3D graphics core

Because it has an ARMv7 processor, it can run the full range of ARM GNU/Linux distributions, including Snappy Ubuntu Core, as well as Microsoft Windows 10 (see the blog for more information).

The Raspberry Pi 2 has an identical form factor to the previous (Pi 1) Model B+ and has complete compatibility with Raspberry Pi 1.

Specification

  • Broadcom BCM2836 Arm7 Quad Core Processor powered Single Board Computer running at 900MHz
  • 1GB RAM so you can now run bigger and more powerful applications
  • Identical board layout and footprint as the Model B+, so all cases and 3rd party add-on boards designed for the Model B+ will be fully compatible.
  • Fully HAT compatible
  • 40pin extended GPIO to enhance your “real world” projects. GPIO is 100% compatible with the Model B+ and A+ boards. First 26 pins are identical to the Model A and Model B boards to provide full backward compatibility across all boards.
  • Connect a Raspberry Pi camera and touch screen display (each sold separately)
  • Stream and watch Hi-definition video output at 1080P
  • Micro SD slot for storing information and loading your operating systems.
  • Advanced power management:
  • You can now provide up to 1.2 AMP to the USB port – enabling you to connect more power hungry USB devices directly to the Raspberry PI. (This feature requires a 2Amp micro USB Power Supply)
  • 10/100 Ethernet Port to quickly connect the Raspberry Pi to the Internet
  • Combined 4-pole jack for connecting your stereo audio out and composite video out





Product Description:
The Raspberry Pi is a single-board computer developed in the UK by the Raspberry Pi Foundation. The Raspberry Pi is a credit-card sized computer that plugs into your TV and a keyboard. It’s a capable little PC which can be used for many of the things that your desktop PC does, like spreadsheets, word-processing and games. It also plays high-definition video


The design is based around a Broadcom BCM2835 SoC, which includes an ARM1176JZF-S 700 MHz processor, VideoCore IV GPU, and 256 Megabytes of RAM. The design does not include a built-in hard disk or solid-state drive, instead relying on an SD card for booting and long-term storage. This board is intended to run Linux kernel based operating systems.



The Raspberry Pi use Linux-kernel based operating systems. Debian GNU/Linux, Iceweasel, Calligra Suite and Python are planned to be bundled with the Raspberry Pi. The Raspberry Pi does not come with a real-time clock, so an OS must use a network time server, or ask the user for time information at boot time to get access to time and date info for file time and date stamping. However a real time clock (such as the DS1307) with battery backup can be easily added via the I2C interface.



Data Reference:
SoC Broadcom BCM2835 (CPU, GPU, DSP, and SDRAM)

Memory (SDRAM): 512 Megabytes (MiB)
Video outputs: Composite RCA, HDMI
Audio outputs: 3.5 mm jack, HDMI
Onboard storage: SD, MMC, SDIO card slot
10/100 Ethernet RJ45 onboard network
Storage via SD/ MMC/ SDIO card slot

Package Included:
1 * Paspberry Pi Model B
