Leo Rover is based on CORE2-ROS electronics board which, together with the Raspberry Pi computer, controls all the Rover's functionalities.
We encourage you to check all the specs of the board itself as there's a great amount of interfaces to be used for further development.

To make it easier, we listed all the interfaces used by the Rover as default. Just to make sure you don't interfere with them when developing.
