|11|2X (stick 2 horizontal)|

|15|+5VDC Source|

Every GND is the same.
Every +5V is the same.

=== Analog Direction Inputs ====

Potentiometer inputs are 0-100kohm, linear. Directional inputs are read by a RC delay circuit, i.e. the time it takes a capacitor to recharge after being discharged determines the potentiometer positions.

    * North=0 ohm between 5V and pin 6 (or 13)
    * South=500 ohms between 5V and pin 6 (or 13)
    * West=0 ohm between 5V and pin 3 (or 11)
    * East=500 ohms between 5V and pin 6 (or 13)

=== Buttons ===

Button inputs have their pins held high by the computer, and are pulled low by the joystick when activated by the user.
