I’m a couple weeks behind on mentioning this one. I will be upgrading mine as
soon as these are generally available (read: amazon prime).
New A72 based quad-core CPU up to 1.5Ghz, 1-4GB of RAM (depending on model),
true 1GbE, dual-band 802.11ac, Bluetooth 5.0 and two USB3 ports.
I’ll be replacing a pair of rpi3b+ currently performing dns, ddclient, internal
web service, etc.
