Scaleway has a 3 euro/month ARM baremetal (and Intel VPS) offering that is higher end than a raspberry pi 3, at least in terms of ram, network + storage -- didn't check CPU.
I use it currently. It's mostly good. They have SAN storage, so you are not limited by what's attached to the thing directly and you also get reliability. The control panel is mostly good. The boxes are speedy and bandwidth is good.
The bad: their ARM boxes don't get IPv6. At all. The VPS's get 16 IPv6 addresses, which is really dumb.
The badder: their ARM boxes and their VPS boxes can't be shut down. You can reboot them, or you can save their local state into block storage, which even for a small box takes many hours (up to a day in one instance for me). You also can't force-detach a volume from a box, so if say your box/VPS got borked, but you had a data volume you want to save, you are SOL.
