A control system for an unmanned vehicle (UV) comprises a housing defining an interior, a first circuit board disposed within the interior, and a second circuit board disposed within the interior. The first circuit board includes one or more processing circuits including a first processing system and a second processing system having heterogeneous field programmable architectures. The second circuit board includes a plurality of interface circuits associated with a plurality of vehicle devices of the UV. The second circuit board is in operative communication with the first circuit board and includes an input/output (I/O) interface between the plurality of interface circuits and the first and second processing systems.
