The Raspberry Pi Concept

21st Century Intelligent Lego!

This tiny yet pwerful computer can be likend to 'Lego' and in fact actually used with 'Lego'. The Raspberry Pi and it's accessories are the building blocks to almost any custom computing project or device that requires a computer to operate it.

The Raspberry Pi Compute Module ~ The core building block for any project

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 compute module contains the guts of a Raspberry Pi (the BCM2835 processor and 512 Mbyte of RAM) as well as a 4Gbyte eMMC Flash device (which is the equivalent of the SD card in the Pi). The BCM2835 is 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.This is all integrated on to a small 67.6x30mm board which fits into a standard DDR2 SODIMM connector (the same type of connector as used for laptop memory*). The Flash memory is connected directly to the processor on the board, but the remaining processor interfaces are available to the user via the connector pins. You get the full flexibility of the BCM2835 SoC (which means that many more GPIOs and interfaces are available as compared to the Raspberry Pi), and designing the module into a custom system should be relatively straightforward as we’ve put all the tricky bits onto the module itself.

So what you are seeing here is a Raspberry Pi shrunk down to fit on a SODIMM with onboard memory, whose connectors you can customise for your own needs.

Raspberry Pi

The Compute Module is primarily designed for those who are going to create their own PCB. However, we are also launching something called the Compute Module IO Board to help designers get started.

But 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.
