Raspberry Pi is a credit Card Sized Computer with which you can do almost everything that you do normally with your PCs or Laptops. You can play Games, write word Documents, watch Videos, browse the Internet, etc. The Raspberry Pi board is bundled with Wi-Fi, Bluetooth, and USB boot capabilities. We can plug in a mouse, keyboard, Connect a Monitor or TV to Raspberry Pi. Raspberry Pi is the cheapest computer with price ranging from $30 to $35.
The Raspberry Pi was bought into the market by Raspberry Pi foundation with an intention to bring the IT field to schools. Its motive was to give students an easy access to build electronic projects and learn to programme using C++, Python, etc. The latest version of Raspberry Pi is Raspberry Pi 3. It was released in February 2016. Well, Raspberry Pi is the combination of 2 words Raspberry and Pi, which comes from Raspbian OS and Python programming language.
Raspberry Pi Hardware:
Just a quick overview of the components on the board:
1 – Processor: The Raspberry Pi 3 uses a Broadcom BCM2837 SoC with a 1.2 GHz 64-bit quad-core ARM Cortex-A53 processor, with 512 KB shared L2 cache and 1 GB RAM.
2 – Ethernet Port: It is a standard Ethernet port where you can plug your Ethernet cable to get access to the Internet. The Raspberry Pi 3 is also equipped with 2.4 GHz Wi-Fi 802.11n (150 Mbit/s) and Bluetooth 4.1 (24 Mbit/s).
3 – USB port: It is where you can plug your mouse and keyboard and other USB devices.
4 – HDMI Port: It is a standard HDMI port which you can connect to a TV or Monitor.
5 – Audio Jack: It is 3.5mm headphone jack for sound output.
6 – MicroUSB (Power Port): It is a standard charging port which is used to charge the Raspberry Pi.
7 – Configurable pins: These are 40 Configurable pins. Each pin can be configured separately to achieve a specific output.
8 – DSI (Display Serial Input Port): It can only be connected with official Raspberry Pi Displays supported by Raspberry Pi firmware. If we connect it to touch-screen displays, it will enable the Pi to be used for controlling all manner of systems with no need for a keyboard or other interface peripherals.
9 – CSI (Camera Serial Interface Port): It can be connected with CSI camera sensors supported by official Raspberry Pi firmware.
On the back of the board, there is a micro SD card slot where you insert your memory card to boot into the Operating System.
How to get started?
Now, you have an overview of the Raspberry Pi hardware. Let’s get into the software part. To get access to Raspberry Pi and use it for various purposes, you have to install an Operating System on to it. There are many Operating System supported by Raspberry Pi such as RISC OS, FreeBSD, NetBSD, etc. But Raspberry Pi foundation recommends the use of Raspbian, a Debian-based Linux Operating System. It can be downloaded from here. Downloaded OS should be installed on to the SD card by inserting the card into the SD card slot. After you have installed the OS, you will be seeing a user-friendly screen. Now, you can get started with coding, watching videos, etc on the world’s cheapest computer.
Raspberry Pi Accessories:
You can stack your Raspberry Pi hardware with certain accessories to increase the functionality of your computer. Some basic Accessories include:-
1. Sense Hat: Hat stands for Hardware attached on top. As the name says, Sense Hat has many onboard sensors present. It has temperature, humidity, pressure and gyroscope sensors present on the board. It also has joystick present on the board to play games on the Pi. It also has 8x8 led segment display.Due to the presence of these components, it is the most popular Hat present. It is also used in IoT projects.
2. Camera: On 14th May 2013, Raspberry Pi foundation launched Raspberry Pi camera along with the firmware update. It is an 8 MP camera. It can be connected with the Raspberry Pi 3 with the help of a flat cable that inserts into the CSI Port. These cameras can record up to 1080p videos as well.
There are many more accessories which can be stacked with Raspberry Pi 3.
Raspberry Pi has sold over 12 million board in five years. It’s one of the coolest techs due to its awesome functionality and very low price. The limitation of Raspberry Pi starts where your Imagination stops.
I hope this information helps. Finally, thank you.
