Upgraded Raspberry Pi 3 delivers more power and faster networking

  • Raspberry Pi Foundation

The upgraded chip supports Gigabit Ethernet, resulting in performance improvement. Despite only having a slight difference in name to the Raspberry Pi 3 B, it actually features significant performance improvements. It has 5GHz 802.11ac Wi-Fi connectivity, 4.2/BLE Bluetooth and Gigabit Ethernet with a maximum transfer speed of 300 Mbps, which is three times higher than Model B. Just over two years ago, the Raspberry Pi 3 Model B was released. To mark this occasion Raspberry Pi Foundation launched the new version small in size and affordable for DIY enthusiasts. The first example was Raspberry Pi 1 Model B+, which added two additional USB ports, introduced our current form factor, and rolled up a variety of other feedback from the community.

Like most new Linux hacker boards, the B+ moves from 10/100Mbps to 10/100/1000Mbps Ethernet. The latter additions will be particularly important for people who use a Pi as a basis for Internet of Things devices (IoT). "This has allowed us to certify the entire board as a radio module under FCC rules, which in turn will significantly reduce the cost of conformance testing". The PoE signals are available in a new 4-pin header. Component manufacturers have created their own workarounds, but the Raspberry Pi Foundation will launch its own dedicated PoE HAT to make use of it in the near future. The New Raspberry Pi 3B+ will not yet be available in South Africa until ICASA approval has been received due to its WiFi capability.

Improved heat management. The Model B+ consumes "substantially more power than its predecessor", the Pi Foundation notes, but it includes a variety of improvements aimed at heat dissipation. The SBC is rated for 0 to 50°C temperatures. We're still looking at support for one HDMI connection, four USB 2.0 ports, as well as display and camera ports.
