GPIO and pi-dac+

I want to use Banana pi m2 rather than Rpi 2 because of more powerful and capable h/w. However, the GPIO add-ons I want to use are compatible with RPi2, but nothing is mentioned about BPi compatibility. Have anyone used pi-dac+ and/or pi-amp+ with this?

Mybe yes the GPIO for RaspiB2 are same as BPI M2 then hardware are mostly compatible,worry about software
