Raspberry Pi just celebrated its sixth birthday—that's six years since the launch of the original Raspberry Pi. Since then, it has released various new models, including the Pi 2, Pi 3, and Pi Zero. So far, 9 million Raspberry Pi 3s have been sold—and over 18 million Pis in total—and those numbers are likely to grow following today's announcement of the Raspberry Pi 3 Model B+. This new Pi features:
- 1.4GHz 64-bit quad-core ARM Cortex-A53 CPU
- Gigabit Ethernet (over USB)
- Dual-band WiFi and Bluetooth
- Power-over-Ethernet (PoE) pins
- Improved PXE and USB booting
- Improved thermal management
This is a big update to the existing Pi 3, including a re-spin of the BCM2837 CPU (running faster at 1.4GHz), new dual-band wireless connectivity (so you can connect to both 2.4- and 5-GHz WiFi networks), better thermal control, and more. As always, you'll need an up-to-date Raspbian SD card, but the new model is backwards-compatible with all previous models and runs the same operating systems and programs. The Raspberry Pi 3 Model B+ is available now at the usual price of $35.
Gigabit Ethernet and PoE
The Raspberry Pi has always suffered an Ethernet bottleneck, throttling network speeds over USB 2.0. The new 3B+ replaces the LAN9514 USB hub with a with a LAN7515 adding Gigabit Ethernet. It's still limited by USB 2.0 but gives a 3x LAN throughput increase, which will please a lot of Pi users with network-hungry applications in the home and in industrial applications.
The addition of four new pins offset from the main GPIO header provides support for Power-over-Ethernet. An official HAT (add-on board) has been designed to provide this feature natively, and it will be
