A brief introduction of Raspberry Pi Development Board
Overview of Raspberry Pi Development Board
A single computer board the size of a credit card is the Raspberry Pi development board. It can perform many of the same tasks as your desktop PC, including word processing, spreadsheets, gaming, and high-quality video playback. The UK-based Raspberry Pi foundation created it. Since 2012, the raspberry pi has been available for purchase by the general public with the goal of creating a low-cost educational microcomputer for kids and students. The Raspberry Pi was developed as a tool to promote learning, experimentation, and creativity. The Raspberry Pi computer is less costly and portable. The majority of Raspberry Pi boards are used to create mobile devices, solar street lighting, and Raspberry Pi projects. Mobile computer technologies experienced a massive rise at the beginning of the twenty-first century, with the mobile phone sector being a major driver of this development. Mobile phones in the 98 percent used ARM technology. The Raspberry Pi would eventually employ an ARM processor core, showcasing the ARM technology.
Model A and Model B are the two main models that the system is available in. These two differ primarily in terms of USB ports. The model A board will use less electricity because it lacks an Ethernet port. Type B, is made in China and including an Ethernet port. The Raspberry Pi has a variety of open-source technologies, including web-based communication, multimedia, and the ability to work with microcontrollers. It is a mobile device’s portability. Easybom is an Electronic Parts Search Platform, you can look at various components like development boards, integrated circuits, resistors, transistors, or others.
Specifications of Raspberry Pi
Memory: The Raspberry Pi has 512 Mb of SDRAM in the more recent version B and 256 Mb in the older version A. In comparison to other Computers, it is a compact device. While the RAM capacity of a typical Computer is measured in gigabytes, the RAM memory used in this kind of application is greater than 256 Mb or 512 Mb.
CPU: The Raspberry Pi’s central processing unit. It is in charge of executing a computer’s instructions through logical and mathematical processes. The ARM11 family processor is used by the excellent raspberry pi. It has joined the Samsung Galaxy phone family.
GPU: The Raspberry Pi’s graphics processing unit (GPU) is a dedicated chip. It is intended to facilitate the manipulation of picture calculations more quickly. The Broadcom video core IV that comes with the Raspberry Pi is compatible with OpenGL.
Ethernet Port: The Raspberry Pi’s Ethernet port serves as the primary entry point for interacting with other gadgets. You can connect your home router to the raspberry pi’s Ethernet connection to access the internet.
GPIO Pins: The Raspberry Pi’s general purpose input and output pins are used to attach to other electrical boards. GPIO pins can take input and output commands via a raspberry pi that has been programmed. Digital GPIO pins are provided by the raspberry pi. Other electronic components are connected to these pins. For instance, you may attach it to a temperature sensor that sends digital data.
XBee Socket: The raspberry pi proves two XBee socket for wireless communication purpose.
Power Source Connector: Power Source Connector: The power source selector is a tiny switch that can be used to activate an external power source. It is situated on the side of the shield.
UART: A serial input and output port is a UART. This can be used to alter the debugging code as well as communicate serial data like text.
Raspberry Pi Development Board Model A
A Broadcom BCM2835 system on chip board powers the Raspberry Pi. The Raspberry Pi has an ARM1176JZF-S core CPU running at 700 MHz together with 256 MB of SDRAM. Only your external data connectivity options are used by the USB 2.0 ports. A micro USB adapter with a minimum current capacity of 500 MA is used to power the raspberry pi (2.5 watts). The purpose of the graphics-specific chip is to expedite the manipulation of image calculations. This Broadcom video core IV cable is useful if you want to utilize your Raspberry Pi to run games and videos.

How to Configure and Launch Your Raspberry Pi
An SD card is included with the Raspberry Pi. We can use an SD card that has been inserted into this slot as our devices. It serves as a primary storage device similar to a PC’s hard disk. The card you intend to use has the bootable operating system loaded on it. Operating systems for the Raspberry Pi include Linux, ARM, Qtonpi, and Mac. One operating system can be chosen, and it must be written on an SD card using a program like Disk Manager. You can also utilize a USB drive or an external hard drive as a storage device. There are numerous brands and sizes of SD cards available on the market. The largest SD card the raspberry pi can support is 64 GB.
You must attach a display, keyboard, and mouse to your Raspberry Pi before you can turn it on. The Pi can output composite video, HDMI video, and DSI video, albeit the latter two require additional hardware.
Advantages of Raspberry Pi Development Board
- affordable ($35)
- massive processing capacity in a little board
- several interfaces (HDMI, multiple USB, Ethernet, onboard Wi-Fi, Bluetooth, many GPIOs, USB powered, etc.)
- Supports Ubuntu, and Python (making it easy to build applications)
- examples that are simple to find and have community support
It will be quite expensive and time-consuming to create such an embedded board.
