A new Raspberry Pi was announced this morning – Model 3B+. It has a more powerful 1.4GHz CPU. It has improved networking, both wired and wireless. Wired has a Gigabit Ethernet adapter, although it maxes out at about 300Mb/s. Wireless is 2.4GHz and 5GHz 802.11b/g/n/ac. The new board has the pins for Power over Ethernet (PoE).
I’ve ordered one to use as a Home Assistant server.
