Difference between normal CAN and 2CAN 2.0?

[otherguy]

Both systems will work. Using the black jaguar as a serial bridge will limit your bandwidth (the serial connection to the first jag is slower than the CAN bus). Using the black jaguar introduces a single point failure, if the first black jag dies or restarts, you can't ocmmunicate with any of the jaguars on the bus. With the 2CAN the single point failure is the 2CAN itself. If it dies, you can't talk to any of the devices on the bus.

That said, I have a follow on question... If you're only going to use it for two motors on your robot, why not just use PWM cables?

Do you need to use one of the features of the Jag that's only available over CAN?
