3V analog and 3V digital out? Does powering the maple board mean 3va 3vd out? If so where and how do I find that on the schematic if it is so.

Powering Maple means selecting either BAT, USB, or EXT on the power selection header and connecting power to one of those. The power selection header determines which of those power sources are connected to what is called VIN on the schematic. VIN is connected to the input of two voltage regulators, one that supplies 3.3V to all the digital supply lines on the STM32 and the other that supplies power to the analog supply pins. The analog and digital supplies are called VDDA and VCC, respectively.

The analog supply, VDDA, is also regulated to 3.3V.
