Cortex Pin Guide
The VEX Cortex Microcontroller coordinates the
ow of all information and power on the robot.
It has built in bidirectional communication for
wireless driving, debugging and downloading
using the state of the art VEXnet 802.11
wireless link. The Microcontroller is the brain of
every VEX robot.
Motor Outputs:
• 2-wire motors and ashlights
can be directly connected and
controlled in ports 1 and 10.
• 3-wire motors and servos can be
directly connected and controlled
in ports 2 through 9.
• 2-wire motors and ashlights can
be connected to ports 2 through 9
using a Motor Controller 29.
Analog Outputs & Digital Inputs / Outputs:
• Analog Outputs are used by any sensors that
provide a range of values. Examples include:
potentiometers, light sensors, line followers,
and accelerometers.
• Digital ports are available for digital input
signals Examples include: bumper switches,
limit switches, ultrasonic range nders, and
optical shaft encoders.
• The digital ports can also be used as digital
