This document presents a hardware interface for an autopilot flight system that can be used for both general aviation and unmanned aerial systems. It describes the hardware diagram and lists the electronic components needed, including microcontrollers, CAN transceivers, and development boards. The components are from manufacturers such as 3DRobotics, Analog Devices, Atmel, and Adafruit and aim to provide modularity between UAV and civil aircraft implementations.

I. Introduction
This document shows the hardware implementation and a list of electronic devices need to
implement the servo interfaces related to the autopilot. This interface must bring an high modularity
to separate the implementation of the UAV servos and the implementation of the civil aircraft
servos using the CANAerospace protocol according to the standards RTCA-DO254(Airbone
Electronic Hardware) and RTCA-DO178C(Software Considerations in Airborne Systems).
