The Brainboard has some pretty cool additional features which you may never
need to use, but they’re here if needed:
!
Unregulated 6V power from the main 4-cell battery pack
!
Microcontroller TTL serial port access (needs external RS232 level shifting)
!
Location for installing external resonator (used for precision timing), which
also can be used as additional I/O (PB6 / PB7)
!
Tap points for utilizing unused PD7 & PB0 pins
