Electrical Rules Questions
 

Can the radio be connected to the 5 volt supply on the Power Distribution board?

Can the 5 volt supply on the Power Distribution board be split to power both the camera and the radio?

Is there a size limit on capacitors?

Can the Operator Console communicate (without driver input) to the robot during the autonomous period?

No, see <R38-B>. The voltage regulator on the radio 12v supply works to a much lower voltage then the camera's 5v supply, and will keep the radio from cutting out when you draw a lot of current (for example making a hard turn late in the match). When the radio loses power, it takes a while for everything to link back up, and there's nothing worse then having a robot dead on the field for 30 seconds.

If it's used as a signal filter for a motor, yes, see <R63>. If it's used in a custom circuit, no. However, inspectors would look very closely at something like a 1 farad capacitor to make sure it doesn't violate <R03>, <R43>, <R62>, <R01>, <R02>, <R86>, and <R87> and probably a few others.

no, the radio can only be connected to the dedicated 12V connection through the Converter provided in the KOP(per rule R38.B)

I don't know about the capacitors, I haven't seen a rule limiting their use.

If I remember correctly, the DS is always communicating with the robot(even during autonomous), however, rules disallow driver input during this time period, such as touching joysticks
