Banana pi M2 zero gpio i2s support?

I want to use the dacberry one with it, and was wondering if it’s supported and how difficult the setup would be? Thanks.

you can see here :

Hi, that was helpful, but I don’t see a mention of i2s and my knowledge is limited. Also no mappings for the gpio pins. Is it identical to a raspberry pi gpio? Thanks.

https://bananapi.gitbooks.io/bpi-m2/content/en/bpi-m2_gpio_pin_define.html , would the mention here mean a sound card using i2s would be compatible?

Looked everywhere, and I don’t think it’ll support a sound card. Will demand a refund.
