A very interesting board indeed, its a zero in its layout, but this time a quad core.. Sadly only a Mali 400Mp2 but it should out perform the Raspberry Zero.
As always though the software isn't here yet, Armbian does a fair attempt at getting it up and running but terrible graphic glitching makes it useless for any kind of graphic systems, and it GLMark2-es seemed to think it had OpenGLES3.0 GPU on board, the Mali 400's are strictly ES2.0 which probably explains why it wasn't able to complete the tests,though it did get quite far into them, though very slow
I'll do an update/upgrade cycle on it from time to time to see if there's any improvement, but for now this is a non starter for our gaming purposes.
Also interesting to note it gets bloody hot, I put a heat sink on it, wouldn't want to run without.
edit... ok I found a slightly older verison of the Armbian/ubuntu test build which installed at 720p and it is much more stable, after update and upgrade it is quite stable, no glitching and GLMark2-es2 worked better, showed as Mali400 and ran all the tests, but it reported a really crap score of 52, which is feeble compared to a Raspberry, even the Zero.
Not sure what to make of this, its quad cores make it a great unit, its crap graphics make it pretty useless, but functional barely. I guess as with all maker boards it depends what you want to do with it, if you need a small cpu system, its amazing.
