Leo Rover is based on CORE2-ROS electronics board which, together with RoaspberryPi 3B+, controlls all the Rover functionalities.
We encourage you to check all the specs of the board itself as there's a great amount of intrfaces 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.
to power the board and RaspberryPi 3B+
hExt P1 pin (I/O)
to control the battery LED (to show the system readiness)
hMot A, B, C & D
to power the Rover motors and encoders
used to flash firmware to the board
(doesn't need to be connected all the time)
