But before soldering I would appreciate an official confirmation. 
If somebody could check the board or if Uriah could confirm, it would be awesome.

I am building my scanner and my pcb.
I had no success with the A4988.
I just received my DRV8834 and will reproduce the new design instead.

The one using the DRV8834 stepper driver.
I identified them in yellow in the following picture.
