Raspberry Pi 3 Model B single-board computer

This Raspberry Pi 3 Model B is a credit-card sized single-board computer built around a Broadcom BCM2837 64-bit ARMv8 quad-core processor running at 1.2GHz. It includes 1GB of RAM, onboard BCM43143 Wi-Fi and Bluetooth Low Energy, plus a 40-pin extended GPIO header. The board provides four USB 2.0 ports, full-size HDMI, CSI and DSI connectors, composite video, and a microSD slot for the operating system. It requires a 2.5A micro USB power supply to support power-hungry USB peripherals.

Makers, educators and embedded developers

The board suits hobbyists learning Linux, teachers running coding clubs, and engineers prototyping IoT gateways or media centres that need wireless connectivity and GPIO access. Buyers who need more than 1GB of memory for heavy desktop workloads or container orchestration should look at a different platform. Projects requiring USB 3.0 bandwidth, Gigabit Ethernet or dual 4K display output will also need alternative hardware.

1GB fixed RAM capacity

The 1GB memory is soldered to the board and cannot be expanded, so it sets the hard limit for simultaneous applications, browser tabs or database buffers. If your workload fits within this ceiling the Pi 3 Model B delivers a complete Linux environment with wireless networking and extensive I/O in a compact form factor.

Questions about this item

What does the 1 GB RAM mean for everyday use?

The board includes 1 GB of system memory, which is shared with the GPU and is sufficient for lightweight desktop tasks, media playback, and many headless server workloads.

How does the 1.2 GHz quad-core ARMv8 processor perform in a real machine?

The Broadcom BCM2837 runs four 64-bit cores at 1.2 GHz, giving noticeably snappier response than earlier single-core models for web browsing, compilation, and multi-threaded scripts.

What does the Micro USB power input capped at 2.5 A mean in practice?

The upgraded Micro USB port accepts up to 2.5 A, allowing the board to drive more demanding USB peripherals such as portable hard drives without a separate powered hub.
