Raspberry Pi 4 Model B — Broadcom BCM2711 1.5 GHz | 8 GB RAM | 802.11a/b/g/n/ac Wi‑Fi, Bluetooth 5.0

Raspberry Pi 4 Model B is a compact, fanless single-board computer designed for quiet, low-power operation. It is powered by a Broadcom BCM2711 running at 1.5 GHz and includes 8 GB of RAM for multitasking and more demanding applications. Key capabilities: - Silent, energy-saving design: fanless construction keeps the board virtually silent while consuming far less power than typical desktop systems. - Networking: Gigabit Ethernet for wired connections plus built-in wireless (802.11a/b/g/n/ac) and Bluetooth 5.0 for flexible connectivity. - USB and I/O: two USB 3 ports and two USB 2 ports; USB 3 enables data transfers up to ten times faster than USB 2. This configuration combines efficient performance with fast networking and improved USB throughput, making it suitable for a wide range of projects and use cases.
