Thank you for your interest in the Intel Aero compute board.
The Intel Aero Compute Board Schematics are not publicly available as the hardware is not open source. You can find a block diagram, connector specifications and the 80-pin IO expansion port pinout in the Intel Aero Compute Board Hardware Feature and Usage Guide. However, certain pins that are marked as “reserved” may or may not be exposed in the future as mentioned on page 2 in the guide. Details around the Atom processor are not publicly available as the processor is not open source, all the available information is included in the guide.
Regarding the Intel Flight Controller included in the Aero RTF Drone, the flight controller information is not publicly available. The flight controller can run PX4 and ArduPilot, similar functionality as the PixHawk flight controller. You can find a high level block diagram on section 6 of the HW features and usage guide.
On the 80-pin IO expansion connector, there are some exposed FPGA GPIO pins that can be used by programming the MAX10 to meet your project’s needs. Please take a look at the following wiki article:
