I'm a little bit confused. In rules (http://drives.feld.cvut.cz/freescalecup/download/The%20Freescale%20Cup%202013%20Rules.pdf) we can find:
"The Microcontroller/Microprocessor Board from Freescale Semiconductor is the core control unit. Only the authorized boards are allowed for use during the official race."
"4. The main microcontroller/microprocessor control board may be modified.
5. Teams are allowed to create custom circuit boards.
6. No auxiliary processor or other programmable device is allowed besides the Freescale microcontroller (see Appendix A for list of authorized controllers)."
I couldn't find Appendix A. But if it exsists, we can build our own board with microcotroller which will replace orginal control boards. Am I right? So the final question is:
Are we allowed to build our own control board?
May the Force be with you:)
