  • 8 bits of digital output capable of driving a total of 75ma continuous current. A single output can drive as much as 35ma of continuous current.
  • 4 digital input and 4 digital output enables controlled by the R/W line and E-clock of the MC68HC11 processor.
  • An H-bridge motor driver with thermal shutoff that can drive two small DC motors with maximum sustained current of 1A through each motor.
  • A stable, crystal-driven, 40Khz clock to modulate IR and sonar.
  • A 16 pin DIP socket for mounting resistors or other discrete components in series with the digital outputs.
  • A 60 pin header providing direct mating to a connector added to the EVBU board.
