If it has a battery then it need/wants power while there is no power on the PD board. It is probably a BIOS battery so you probably need it to boot.

As I suggested on the other thread read about the Adam Bots CoProcessor. Although it is geared for the 2007 IFI system, it should give you an appreciation for the task of developing a coprocessor and some info on using Gumstix form a team that has done it before.

You cant legally use a coprocessor to control anything directly <R03>. The Crio still has to set all outputs to speed controllers etc... You can use the coprocessor to communicate with the Crio via Ethernet Port 2, RS 232, SPI, CAN etc... Please read the manual particularly the robot section before buying anything. Unlike the battery and the cost accounting issues, <R03> no custom circuit (coprocessor) affecting outputs is a straightforward basic rule that should have known if you read the manual.
