The game manual talks about cRIO/Sidecar connection in section 4.3.10 but it says nothing about how many sidecars we can connect to the cRIO. Can we only have one sidecar or can we use more, because my team is thinking about using two sidecars.
The software on the cRIO only allows for 2 digital modules to be connected (one in slot 4 and one in slot 6). Therefore, only 2 sidecars can connect to a cRIO. There is nothing in the rules that prevents 2 sidecars from being used on a robot.
