I know similar questions (regarding a Bitcoin Full Node) were already asked here, but they date all back to 2014 and I think especially the space needed by the blockchain changed a lot since then.
I am thinking of buying a single-board-computer to turn it into 24/7 online bitcoin full node + a lightning node. I want a single-board-computer to reduce the energy consumption, since it is running 24/7. My question is now what single-board-computer I should buy and how well that works. I read a lot about Raspberry Pi 3 and that its not working very well so I think of buying something more powerful.
At the moment I am thinking of a Banana Pi M3 or an ODROID-XU4.
Did someone already try something like this with another single-board-computer than the Raspberry Pi 3?
