The hardware is new but has some components/methods used by the Cougar. The components can support up to 400 volts from the battery pack. The design split the base controller from the switching circuitry so you can drive IGBTs or mosfets in whatever configuration you come up with as long as the driver board supports it (them).
The cpu is the atmega1284P which has a lot more ROM and RAM. And it supports more pin ins and outs.
The software is based on the cougar version 1.11b, but has had major modifications made to it including a micro TCP stack for ethernet communications.
Hope that answers your question. I'm sure Adam could provide more details on the hardware, but I think he is taking a much needed vacation where he has no connectivity to the net..........yeh, sure.
