The Raspberry Pi Foundation has announced the new Raspberry Pi 3 Model B+. This incremental design improvement provides some interesting features.
- 1.4GHz 64-bit quad-core ARM Cortex-A53 CPU
- Dual-band 802.11ac wireless LAN and Bluetooth 4.2
- Faster Ethernet (Gigabit Ethernet over USB 2.0)
- Power-over-Ethernet support (with separate PoE HAT)
- Improved PXE network and USB mass-storage booting
- Improved thermal management
The 5 GHz wifi and power over ethernet capabilities are especially interesting improvements. The Raspberry Pi is a great experimenter’s computer. Many amateur radio operators and makers are using them in purpose built applications such as digital hotspots and home control. You can see more here.
Update: 03/19/2018 — One difference that I failed to note betwee the RPI 3 Model B and the B+ is that while the RPi 3 Model B sported 1 GB of RAM, the B+ cuts it back down to 512 MB. While 512 MB may be enough for your application, if it is not, you may with to stick with the original RPi 3 Model B.
Update: 05/03/2018 — I have verified that RPi 3 Model B+ does still have 1 GB of RAM. The reference to 512 MB RAM came from the specifications listed on the RPi Foundation web page when originally released.
