CAN transceivers

The RDDRONE-FMUK66 features two CAN (Controller Area Network) busses. PX4 implements the UAVCAN protocol, and supports some motor controllers, sensors and GPS solutions with a CAN interface. The current HoverGames kit does not include any hardware with a CAN interface, except the FMU itself.
