Raspberry Pi 4 Model B is a completely upgraded and re-engineered version of the Raspberry Pi family. It features a significantly more powerful processor (a quad-core Cortex-A72 CPU), offering much better performance compared to previous models. The device also supports faster networking options, including Gigabit Ethernet, dual-band Wi-Fi (2.4 GHz and 5 GHz), and Bluetooth 5.0, making it ideal for high-speed data communication. Moreover, it can drive two monitors simultaneously using its dual micro-HDMI ports, each supporting up to 4K resolution, allowing for extended or mirrored displays. Lastly, the Raspberry Pi 4 is available with multiple RAM configurations (2GB, 4GB, or 8GB of LPDDR4-3200 SDRAM), giving users the flexibility to choose the version that suits their performance and budget needs.
