4 robot electronics questions

[FRC41]

On the cRIO the second ethernet port is allocated for the camera. By reading R67 we cannot use it for anything else. Additionally we could not use the serial port on the cRIO. Also there is an I2C port on each digital sidecar. By R67 we cannot use it either. Are we not allowed to use them or is this just missing from the rules?

Is there a limit on a capacitive load we can have on a circuit?

What wire gauge is required for supplying power to the digital sidecar (DSC)? Do we default to <R45C> since the DSC is connected to a 20A breaker?

Given that the RSL pins on the DSC are current limited at 2.2 Amps, can we use a wire gauge smaller than the 18 AWG required by the wire gauge rules <R45C> for a 20 Amp breaker?

Thanks,

The only devices that can be connected to the ethernet ports on the cRIO are the provided camera and wireless bridge. The serial port on the cRIO is not available for use this year. Nothing can be connected to this port.

Rule <R45> specifies minimum wire sizes for circuits used on the ROBOT, including the 20-amp circuit that supplies the Digital Sidecar.
