I want to upgrade my Proto1 Centepeedes to a Proto 2 3volt board. Im going with Proto 2 not 3 because I want to have the 2nd unit as a slave unit with the 2 motors and smoke. Proto 3 requires a separate upgrade for each unit.
So my question is, can i place the Proto 2 board in the front unit and still use the existing slave board in the trailing unit? Or will I have to replace the boards in both?
