The Raspberry Pi 4 Model B is equipped with the modern Broadcom BCM2711 chip, which integrates a 64-bit Quad-core ARM Cortex-A72 processor clocked at 1.5 GHz. This version features 8GB RAM, providing the necessary power for demanding applications, comfortable multitasking, and handling large volumes of data. The upgraded processor architecture delivers significantly higher speeds compared to previous generations. It is the ideal foundation for building compact computing systems with high processing power requirements.

In the area of graphics and display, the Raspberry Pi 4 features two microHDMI outputs, allowing two screens to be connected at the same time. It supports playback and display of content in 4K resolution, delivering excellent clarity and image detail. This feature makes it an excellent choice for building advanced home entertainment systems (Media Centers) with applications such as Kodi. In addition, it is suitable for professional digital signage systems and the display of advertising material.

The device offers full networking capabilities thanks to the Gigabit Ethernet (1000Mb/s) port for ultra-fast wired connections, as well as support for Bluetooth 5.0 for wireless communication with peripherals. For connecting external devices and storage media, it features two high-speed USB 3.0 ports and two USB 2.0 ports. The system is now powered via a modern USB-C port. The GPIO pin layout remains the same as the previous version for compatibility with projects, although due to the changes in the ports, new cases are required.

Thanks to its versatile technical features, the Raspberry Pi 4 can be used in a huge variety of applications. It is ideal for creating RetroPie emulators for retro consoles, central smart home servers, as well as Pi-hole proxy servers for blocking ads across the local network. At the same time, it can function as an affordable web server, a central alarm unit with motion sensors and cameras, or even as a fully functional low-power desktop computer.
