What is a Raspberry Pi Board?

The Raspberry Pi board is a credit card-sized device that was developed in the United Kingdom to promote computer science education. This device is developed by Raspberry Pi. Its objective is to develop an education system mainly related to the field of computer science for children and adults. The Raspberry Pi board acts like a mini-computer that is completely based on the LINUX operating system.

Raspberry Pi Board is available in the market at low size and low cost. The Raspberry Pi board is currently popular for uses such as robotics. If we talk about its connectivity, then you can plug it into the TV and along with it, it can also be plugged into the computer monitor as per the requirement. Connecting this device with a mouse and keyboard is also very easy. Whether you are a student or an old man, all of you can easily write programming languages like Python and Scratch with the help of this device. 

The Raspberry Pi board is primarily capable of browsing the Internet and playing HD video or non-HD video. Along with this, with its help, we can easily make typing, gaming, and spreadsheets. If we talk about its projects, then with the help of it we can easily complete Weather Station, IR camera, Digital Project, Music Machine and other Raspberry Pi projects.

It can improve hardware programming and other programming skills mainly in colleges, schools, and higher education departments. If we compare it with desktop or laptop, then we will find that its speed is less than desktop or laptop. Although its price in the market is low.

Different Types of Raspberry Pi Board Models

The different types of Raspberry Pi Board models are as follows;

Raspberry Pi Zero W is a member of the Pi Zero family. As the name suggests, the cheapest and smallest package of Raspberry Pi Foundation is Raspberry Pi Zero W. If we talk about the features of Raspberry Pi Zero W, then it provides all other features except features like HDMI, camera I/O, and micro USB, standard GPIO and SD card. In fact, it gives the feel of a small computer.  

If we talk about its size, then its size is special compared to other types of Raspberry Pi Boards. Because it comes with additional Bluetooth connectivity and wireless LAN as compared to others. Apart from this, a micro SD card is installed with the operating system in it. It comes with a micro USB power supply as well as a camera cable. However, instead of the USB A port, USB Micro B has been used as the input. The next Raspberry Pi Boards in this series were developed to overcome the lack of Wi-Fi, direct USB ports and other peripherals.

The Raspberry Pi 1 Model B is an important version of the Raspberry Pi family, offering 4 USB 2.0 ports instead of 4. The old friction-fit SD card socket was replaced with a nicer push-push micro SD version. In fact, this version of the Raspberry Pi uses a different form factor than the other versions.

If we talk about the audio quality of Raspberry Pi 1 Model B, then it provides better audio quality than other versions. It has the USB connector aligned with the edge of the board and uses a 3.5 mm jack for video. It has more GPIO pins than the earlier version. Where earlier 26 pins were used, now its number has been increased to 40. If you look at the power consumption, the power consumption in the Raspberry Pi 1 Model B has been changed from switching regulators to linear regulators from 0.5 watts to 1 watt.

The Raspberry Pi 2 Model B is the second-generation member of the Raspberry Pi family. Its biggest feature is that it has been given the facility of 1GB RAM with 900MHz quad-core ARM Cortex-A7 CPU. Along with this, 100 Base Ethernet, 4 USB ports, and 40 GPIO pins have also been provided like the previous version. It has a Full HDMI port with VideoCore IV 3D graphics core. 

The Raspberry Pi 3 Model A+ is a revamped version of the Raspberry Pi 1 Model A+ that weighs around 29 grams. This version of Raspberry Pi uses a 1.4GHz 64-bit quad-core processor and dual-band wireless LAN. It is available in 512 MB RAM with 4.2/BLE Bluetooth. 

Apart from this, if we talk about power input, then Raspberry Pi 3 Model A+ consumes 5V/2.5A DC power input. It has a CSI camera port to connect the camera. Along with this, a CSI camera port has been given to connect to Raspberry Pi Touch Display. 

The Raspberry Pi 4 Model B was developed to address the shortcomings of previous versions of the Raspberry Pi. Like the previous versions, features like WiFi, Bluetooth have been provided for connectivity in this too. It is available in the market with 8GB, 4GB, and 2GB of RAM. It has a 2-lane MIPI DSI display port and a 2-lane MIPI CSI camera port for display and camera port.

Talking about the USB port, USB can be connected with the help of 2 USB 2.0 ports and 2 USB 3.0 ports. 2 × micro-HDMI ports have also been provided in this USB port. There is a provision of a Micro-SD card for data storage and loading operating system. Keep in mind that its operating temperature should be minus 50 degrees Celsius ambient.
