Raspberry Pi 3 B+ – Updated Features, Specs & Buying Guide

Raspberry Pi 3 B+ Overview

The Raspberry Pi Foundation’s latest credit‑card sized computer brings significant performance and connectivity upgrades over its predecessor. Powered by a 1.4 GHz 64‑bit quad‑core ARM Cortex‑A53 CPU, it delivers faster processing while consuming only a modest amount of power.

Key Enhancements

• 1.4 GHz 64‑bit quad‑core ARM Cortex‑A53 processor
• Dual‑band 802.11ac Wi‑Fi (2.4 GHz & 5 GHz) with Bluetooth 4.2 / BLE
• Gigabit Ethernet over USB 2.0 for high‑speed wired networking
• Power‑over‑Ethernet (PoE) capability via an optional PoE HAT
• Improved PXE network and USB mass storage booting
• Enhanced thermal management for stable operation under load

Specifications

The board runs on a BCM2837B0 chip, an updated version of the processor used in the Pi 3 B. The increase in clock speed comes with lower power draw and better temperature monitoring, ensuring reliable performance during long‑term use.

Connectivity

The dual‑band Wi‑Fi module is fully certified, enabling quicker time‑to‑market for commercial products. The Proant PCB antenna, identical to that on the Pi Zero W, provides robust wireless coverage. Users can switch between 2.4 GHz and 5 GHz to avoid congestion and maintain optimal speeds.

Power Requirements

While the Pi 3 B+ draws slightly more power than earlier models, a 5 V supply capable of delivering at least 2.5 A is recommended for stable operation.
