Raspberry Pi version 4B offers big changes from previous models.
\nThe device retains the GPIO ports known from previous versions, 4 USB ports (including 2 supporting the USB 3.0 standard and two USB 2.0).
\nIn addition, there is an Ethernet connector on the board.
\nNew are 2 microHDMI sockets, which have replaced the full-size HDMI connector.
\nIn addition, changes have been made to the power system, replacing the micro USB socket with a USB C socket. In practice, this means the possibility of using power supplies with high current capacity.

RPi 4 - kits (main module and accessories)<\/span><\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t

The Raspberry Pi<\/strong> range includes a wide selection of kits<\/strong><\/a>, which, in addition to the main device, consist of practical accessories to facilitate the use and development of projects.
\nSome of the more popular sets include the Raspberry Pi 4B with 8GB of RAM<\/strong><\/a>.
\nThe minicomputer is equipped with a powerful Broadcom BCM2711<\/strong> processor and a quad-core 64-bit ARM-8 Cortex-A72<\/strong> processor clocked at 1.8 GHz.
\nIt also comes with a USB-C power adapter with an output voltage of 5 V and a capacity of 3 A. Another feature is the fan-assisted design, which not only protects the device from mechanical damage, but also provides active cooling. <\/p>\n

What else can be found in the kits? A microHDMI cable<\/strong> <\/a>allowing you to connect your Raspberry Pi to a monitor.
\nSuch a cable allows you to display high-definition video.
\nIn addition, the kits include memory cards<\/strong><\/a> with a capacity of, for example, 32 GB with NOOBs, which is the installation system.
\nThe memory card comes ready with pre-installed software, allowing for a quick start.
\nSome kits also include a cable Ethernet<\/strong><\/a> used for a stable connection to the Internet. <\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

NOOBS<\/strong> (from New Out Of the Box Software) is the official system for Raspberry Pi computers<\/strong>, developed by the Raspberry Pi Foundation.
\nIt’s a simple installer that allows users to easily install various operating systems on Raspberry Pi devices. <\/p>\n

NOOBS is designed to make it easier for beginners to take their first steps with the Raspberry Pi, eliminating the need to prepare an SD card with the operating system beforehand.<\/p>\n

NOOBS stands out for its simplicity and accessibility for those new to the popular “raspberry.”
\nIt allows you to select and install your preferred operating system from an easy-to-use menu. <\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

The main advantages of the software include a wide selection of operating systems<\/strong>.
\nUsers can easily and quickly install, among others.
\nRaspbian, Pidora, Arch, Linux and other systems.
\nIn addition, NOOBS makes it easy to reinstall or change the operating system<\/strong>, without using another computer.
\nIn addition, the software can be used in a Lite<\/strong> (online) version<\/strong> that requires an Internet connection, to download selected operating systems or the full version.
\nThe Lite version already contains images of several operating systems available for immediate installation (offline). <\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t
\n\t\t\t\t\t

How do I install NOOBS on the RPi 4?<\/span><\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

To begin with, you need to properly prepare a memory card in SD format<\/strong> with a capacity of more than 8 GB<\/strong>.
\nNext, the card needs to be formatted to FAT32<\/strong> file format, such as using media formatting software.
\nThe next step is to download NOOBS or NOOBS Lite<\/strong> software.
\nThe safest and most up-to-date source is the Raspberry Pi official website<\/strong><\/a>.
\nAfter unzipping the ZIP archive, a folder containing the NOOBS installation files will appear. <\/p>\n

All downloaded and unzipped files need to be copied to the SD card.
\nIn addition, make sure that the files are in the main directory of the card and not in an additional folder. <\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t
\n\t\t\t\t\t

How does the software installation work?<\/span><\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

You need to insert the SD memory card<\/strong> with the copied files into the Raspberry Pi slot.
\nIn the next step, you need to connect the monitor, keyboard and power supply<\/strong> to the Rpi4.
\nOnce properly connected, the device should automatically boot up and display the NOOBS menu.
\nThen, in the NOOBS menu (using the keyboard), select the operating system to be installed.
\nIt is worth remembering that nothing prevents you from selecting more than one system.
\nYou will be able to select the operating system every time you boot the Raspberry Pi. <\/p>\n

In the next step you need to click “Install”, which means install.
\nA warning should appear that all data on the SD card will be deleted.
\nYou need to confirm this, then the installation process will begin. <\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t
\n\t\t\t\t\t

Completion of the installation process<\/span><\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Installing the operating system may take a few minutes (depending on the system(s) selected).
\nOnce the installation is complete, the Raspberry Pi will automatically boot with the newly installed operating system.
\nIf more than one system is installed, a menu for selection will appear at startup.
\nIf everything went successfully, the RPi 4 is fully ready for use. <\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
