    • Stores pedal calibration data in flash non-volatile memory

    • Refer to FW15 Pedal Board Design for more documentation! This board has been merged to CC. It is almost the same, but it doesn’t use the MAX11600. It instead uses a pedal that we ripped off a car

  • Steering Stalk

    • Toggles Left/Right lights

    • Toggles Cruise Control

    • Refer to FW15 Steering Design for more documentation! This board was merged to CC so it hasn’t really changed
