I have been playing with Orange Pi Zero and its been quite interesting to explore the ecosystem given that it has a Pi interface, in addition to that there is another series of pins that are exposed it is called Orange Pi Zero interface and it has also got an add-on board to it. The pin out of the interface is shown below.
It has two USB slots, stereo audio output, mic input, TV out and IR receiver. I have tested couple of the peripherals in the interface board which I will be posting soon. It is a very useful add-on if you want to extend your USB slot or work with IR or any audio multimedia application.
I bought it from Banggood.com if you are interested in buying them, then you can check my affiliate links below.
