How to find support/literature/manual/forum issues for Arduino M0 PRO (Zero)

Hello,
I want to simulate an incremental encoder for a virtual wind turbine with an Arduino M0 PRO.
The DAQmx cards of my labview system is not able to build signals with frequency up to 30000Hz and a second signal with 90° phase (sampling frequency has to be 4*fsignalMax in this case).
Because of this, I choose an Arduino M0 PRO.
The support of this board is very rare because it's new.
Most comments, supports and issues are about Arduino UNO.

My question is:
Is there any support/literature/manual/forum issues for this board?

Thank you for your tips :wink:
