M2 Berry schematics

Where to get the schematics of M2 Berry (the one with SATA and SATA power) ? I have found some versions of schemstivs in the web, but always not of M2 Berry with SATA. I want to power the M2 from the 40 pin header and I want to know how the SATA power pins are connected to 5V. All the schematics I have found do not show this.
