The Raspberry Pi is a mini-computer that is series of small single-board computers. It was officially propounded on February 29, 2012.
A series of small single-board computers developed in the United Kingdom by the Raspberry Pi Foundation in association with Broadcom. It is also known as RPi as well Raspi. This project is specially established to teach introductory computer science in schools/colleges and developing countries.
This project stands for the fifth generation.
Application:
The raspberry pi boards are used in many applications like Media streamer, Arcade machine, Tablet computer, Home automation, Carputer, Internet radio, Controlling robots, Cosmic Computer, Hunting for meteorites, Coffee and also in raspberry pi based projects.
The main intention of this project is to control the speed of a DC Motor using Raspberry Pi.
Problems:
Raspberry Pi is an instrumental substance. However, it contains some problems with it.
Some of them are:
Architecture: Raspberry Pi is a credit-card-sized single-board computer designed and manufactured by the Raspberry Pi foundation in the United Kingdom.
It has an ARMv6 700 MHz single-core processor, a VideoCore IV GPU, and 512MB of RAM. It uses an SD card for its operating system and data storage.
The Raspberry Pi officially supports Raspbian, a lightweight Linux OS based on
Debian. It took the team six years of hardware development to create the Raspberry Pi
makers, and electronics enthusiasts adore today
Raspberry Pi: History: In 2012, the team started its first production run consisted of 10,000 Raspberry Pi units manufactured by foundries in China and Taiwan.
Unfortunately, there was a manufacturing issue where the ethernet jack on the
Raspberry Pi. This incident caused some minor shipping delays.
Model B: In April 2012, the original Raspberry Pi, also known as the model B, was launched.
It offered an ARMv6 700 MHz single-core processor, a VideoCore IV GPU, and 512MB of RAM, all packed in a credit card size board.
Model B supported 26-pin GPIO and an SD card slot for loading the operating system. Priced at $35 per unit.
Model A: In February 2013, it upgraded and launched Model A. It packed the same ARM single-core processor and the GPU as model B with half of the RAM capacity at 256MB.
Priced at $25 per unit, model A could be regarded as the cheaper and less powerful version of model B.
Model B+: In July 2014, the Raspberry Pi Model B+ was launched. It was a worthy successor to the original Raspberry Pi.
Packing the same processing unit as its predecessor.
The model B+ received two more USB ports, an updated 40-pin GPIO layout, and a micro-SD card slot for loading the operating system.
Priced at $30 per unit, the Model B+ was cheaper and offered more connectivity than model B, Making it an ideal choice for education.
Model A+: In November 2014, the Raspberry Pi model A+ was launched, It offered improved specifications over the model A.
Packing the same processor as its predecessor, the model A+ upgraded RAM capacity from 256MB to 512MB. Smaller footprint, 40-pin GPIO, and micro-SD card.
Priced at $20 per unit, the model A+ was the smallest and cheapest single-board computer at that time.
Raspberry Pi: Future scope: The best general-purpose Raspberry Pi for the money is the Raspberry Pi 4 B (2GB). It is powerful enough for almost any project you throw at it and even for some light web surfing. However, if you can spare an extra $20, you can't go wrong by getting the 4GB unit.
The eight different models vary in RAM, CPU core, CPU speed, physical size, network connectivity, peripheral expansion, etc. For example, if you want the most robust solution with more "horsepower," you probably will want the Raspberry Pi 3 B+, which has the most RAM, fastest CPU, and largest number of cores.
Raspberry Pi is a mini computer itself. We can do anything (almost) a Linux box can do using a Raspberry Pi
This development board has taken its place on top of all Single Board Computers available in the market when it was introduced to public. This is due to the ease with which applications can be developed as well as wide scope of Projects that can be build using this tiny board. The cost of this board is very low when compared to other boards with the same specs..
Another reason why we say Raspberry Pi has a great future ahead is their active community. Raspberry Pi have an active community which support young enthusiasts and hobbyists, helping with new Raspberry Pi Projects, developing newer boards and technology while still providing support to older Raspberry Pi versions - Software as well as Hardware.
