I believe there is a newer orange pi than that one. They made it to compete with the pi zero w and it has really good specs and added Bluetooth compared to the zero w. I've been looking into it as a neat little project and the orange pi's seem to give you more for your money. The only downside I can see versus the pi is that apparently the software community isn't as big, but I mean if you are going to use retro arch you are probably ok either way.
