I have been playing with Orange Pi Zero and its been quiet 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 addon board to it. The pinout 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 addon 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.
