I see the same components, & only with the addition of a telephone/modem/fax type cable added to the components similar to the way VEX uses to hook up controllers, I don't see much speculation that can come from this?
So... what's the big deal & all the fuss about?
And what the heck is CAN?
Just a little lost over here... I'm mechanical, not electrical! lol

CAN is a method of communication that allows many devices to talk to each other. Think of it as ethernet, but much simpler.
PWM (as we use it) is a method of communication that allows one device to command another: One piece of information, one direction.
The advantage CAN provides is that more types of information can be sent, and it is bi-directional. This would
potentially allow you to:
- Access the Jaguars back-emf and current measuring capabilities.
- Current and voltage control, rather than just duty cycle control.
- Internal PID loops
- Virtual Springs - Combine torque(current) control with built-in quadrature encoder/pot inputs.
- Active load-sharing: Have motors that share a tough-box balance their loads.
- Lots of other cool stuff.
