Raspberry Pi

A British company, Raspberry Pi foundation, developed a series of small credit-card-sized circuit boards that have all the basic hardware components of a computer (i.e. memory, processor, etc.) and other features (i.e. HDMI, video, sound, USB, etc.). These were invented with the purpose to assist people in learning basic programming and how to program the computer.

The low cost of Raspberry Pis and few features make them ideal for beginners and young people who are interested in web designing and electronic product development.

Soon they gained popularity and became one of the best British best-selling microcomputers of all time. They also captured the interests of innovators and hobbyists, who greatly explored their potentials and tested various new ideas.

The word ‘Raspberry Pi’ was inspired by the tradition set by IT manufacturers who incorporated a fruit as their company name, such as Apple, Acron, and Blackberry, etc. However, it also indicated its function.

‘Pi’ is a short form of Python Interpreter, which is the main programming language of Raspberry Pi. However, those who are not familiar with Python can use Scratch, which is a visual and easy programming language.

A Raspberry Pi serves as a hard drive with an integrated Central Processing Unit (CPU). It is recommended to use Debian-based Raspbian, however, you can also use other Linux and Windows versions.

For power supply, a micro USB charger can be used. You can set up an internet connection with a network cable over LAN. In addition, it is easy to connect different external devices such as a keyboard, mouse, or an external hard drive through HDMI. Several pins can be programmed for extra features.

The manufacturer has launched various models. All these features vary according to the model type. Raspberry Pi 1 was launched in February 2012 and is the most powerful and latest model.

It is best for projects that require extensive processing. It boosts performance and increases memory. It is reliable, versatile, energy-efficient, and open source. It was launched in June 2019 with a 1.5 GHz 64 bits CPU, WLAN, Bluetooth (5.0), Gigabit Ethernet, and two 4K HDMI screen connections. You can choose between 2, 4, and 8 GB processing memory.

Raspberry Pi 3 B+ is also great for a variety of projects due it enough processing power and ease of access. It offers a 1.2 GHz 64 bits CPU, USB Wi-Fi, and Bluetooth connectivity.

Raspberry Pi Zero is compact, cheap, and less powerful than other models. This makes it ideal for portable and small projects. Other models include Pi 1, Pi 2, etc. all with a face value of around $35.
