The Pin64 A64+ is the first single-board computer with a 64-bit CPU (Allwinner A64, quad core ARM Cortex A53). I bought these in 2015 as part of a Kickstarter campaign, and I messed with them off and on for a couple of years, but never used them for anything serious. I bought the WiFi modules which provides 802.11 b/g/n speeds. Both boards come with 32GB SDHC cards, one of them has login info, the other I'm not sure if I have it.
They work fine. There were some issues on these boards to be aware of that affect performance but not overall functionality:
o The wired 1G Ethernet port maxes out at about 800Mbit/sec
o The CPU does not run at its rated 1.2GHz
o The Mali GPU had limited driver support, mainly Android if I recall correctly
These would be fine for use in homelab applications like PiHole, etc. You'll need a 5V/2A power supply with a Micro USB connector to power them.
