Raspberry Pi Technology Introduction, Specifications, Seminar Abstract, Technical Report.

I have gathered more information about the Raspberry Pi, a low-cost, credit-card-sized computer that plugs into a computer monitor or TV and uses a standard keyboard and mouse.

It is a capable little device that enables people of all ages to explore computing and learn how to program in languages like Scratch and Python. It can do everything you would expect a desktop computer to do, from browsing the internet and playing high-definition videos to making spreadsheets, processing words, and playing games.

Moreover, the Raspberry Pi can interact with the outside world and has been used in a wide array of digital maker projects, from music machines and parent detectors to weather stations and tweet birdhouses with infrared cameras. We want to see the Raspberry Pi being used by kids worldwide to learn to program and understand how computers work.

Raspberry Pi Software support

Several official distributions (distros) are available on the official downloads page. New users will find the NOOBs installer the easiest to work with, as it walks you through the download and installation of a specific distro. The recommended distro is Raspbian, specially designed for the Raspberry Pi, and our engineers are continuously optimising. Still, replacing the root partition on the SD card with another ARM Linux distro is a straightforward process, so we encourage you to try out several distros to see which one you like the most. The OS is stored on the SD card.

The Raspberry Pi Foundation recommends Python as a language for learners. Any language which will compile for ARMv6 can be used with the Raspberry Pi, though, so you are not limited to using Python. C, C++, Java, Scratch, and Ruby all come installed by default on the Raspberry Pi.

Some people have put Windows 3.1 on the Raspberry Pi inside an x86 CPU emulator to use specific applications, but trying to use a version of Windows even as recent as Windows 98 can take hours to boot into and may take several more hours to update your cursor every time you try to move it. We don’t recommend it!

Raspberry Pi Hardware supports

The Model B and Model B+ versions of the device have built-in 10/100 wired Ethernet. There is no Ethernet on the Model A version.
No model of the Raspberry Pi has built-in Wi-Fi, but all three can support a USB Wi-Fi dongle.
The SoC does not support native Wi-Fi, and adding a built-in Wi-Fi chip would significantly increase the cost of the Raspberry Pi.
The Ethernet is attached via the USB 2.0 bus, so the upstream bandwidth would not support Gigabit.

Raspberry Pi Compute Module 4 IO Board

Raspberry Pi Compute Module 4 (CM4) is a compact system-on-module (SoM) designed for industrial applications, and it doesn’t come with an IO (Input/Output) board by default. However, there are IO boards available separately that can be used with the Compute Module 4 to provide additional interfaces and connectivity options.

The official IO Board for the Raspberry Pi Compute Module 4 is known as the “Compute Module 4 IO Board.” This IO Board is designed to make it easier to prototype and develop with the Compute Module 4. It includes various ports and connectors to access the features of the Compute Module 4, such as HDMI, USB, Ethernet, GPIO, and more.

Key features of the Compute Module 4 IO Board may include:

  1. Power Supply: It provides power to the Compute Module 4 and peripherals.
  2. USB Ports: USB connectors for connecting external devices.
  3. Ethernet Port: For wired network connectivity.
  4. HDMI Port: To connect a display.
  5. Camera and Display Connectors: For connecting the Raspberry Pi Camera Module and Display Module.
  6. GPIO Headers: General-purpose input/output headers for interfacing with external devices and components.
  7. MicroSD Card Slot: For storage and booting the Compute Module 4.
  8. Debugging and Programming Interfaces: Such as JTAG and UART connectors.

The Making of Pi

The idea behind a tiny and affordable computer for kids came in 2006, when Eben Upton, Rob Mullins, Jack Lang and Alan Mycroft, based at the University of Cambridge’s Computer Laboratory, became concerned about the year-on-year decline in the numbers and skills levels of the A Level students applying to read Computer Science. From a situation in the 1990s where most of the kids applying were coming to interview as experienced hobbyist programmers, the landscape in the 2000s was very different; a typical applicant might only have done a little web design.

Something has changed the way kids interact with computers. Several problems were identified, the colonisation of the ICT curriculum with lessons on using Word and Excel or writing webpages; the end of the dot-com boom; and the rise of the home PC and games console to replace the Amigas, BBC Micros, Spectrum ZX and Commodore 64 machines that people of an earlier generation learned to program on.

There isn’t much any small group of people can do to address problems like an inadequate school curriculum or the end of a financial bubble. But we felt that we could try to do something about the situation where computers had become so expensive and arcane that programming experimentation on them had to be forbidden by parents; and to find a platform that, like those old home computers, could boot into a programming environment.

By 2008, processors designed for mobile devices were becoming more affordable and powerful enough to provide excellent multimedia, a feature we felt would make the board desirable to kids who wouldn’t initially be interested in a purely programming-oriented device. The project started to look very realisable. Eben (now a chip architect at Broadcom), Rob, Jack and Alan teamed up with Pete Lomas, MD of hardware design and manufacture company Norcott Technologies, and David Braben, co-author of the seminal BBC Micro game Elite, to form the Raspberry Pi Foundation to make it a reality. The Raspberry Pi Model B entered mass production three years later through licensed manufacturing deals with element 14/Premier Farnell and RS Electronics. Within two years, it had sold over two million units.

We don’t claim to have all the answers. We don’t think that the Raspberry Pi is a fix to all of the world’s computing issues; we do believe that we can be a catalyst. We want to see affordable, programmable computers everywhere. We want to break the paradigm where families can’t use the internet without spending hundreds of pounds on a PC. We wanted to own a truly personal computer to be expected for children and were looking forward to what the future has in store.
