• High quality video. Two micro-HDMI ports support 4K resolution output to two monitors simultaneously.

• Built-in wireless modules. Dual-band Wi-Fi 802.11 b/g/n/ac and Bluetooth 5.0 BLE for seamless connectivity .

• Flexibility of connections. The 40-pin GPIO connector allows the connection of thousands of sensors and expansion modules.

What is Raspberry Pi 4 Model B and how does it work

The Raspberry Pi 4 Model B is a Broadcom BCM2711 system on a chip (SoC) that combines a powerful processor and graphics core. You can install a Linux operating system (such as Raspberry Pi OS) on it from a microSD card and use it as a full-fledged computer for surfing the Internet, programming, or creating multimedia centers .

Thanks to the presence of USB 3.0 and Gigabit Ethernet, this model has become an excellent candidate for the role of a budget network storage or server. For lovers of robotics and DIY projects, GPIO pins open up the world of controlling LEDs, motors, and reading sensor data . It is important to note that for stable operation it is recommended to use a high-quality 5.1 V / 3 A power supply with a USB Type-C connector and provide good cooling, for example, a passive metal case.
