Built-in VEXnet Technology: Wireless driving, wireless debugging, and wireless downloading. Compatible with either the first generation VEXnet USB Key or the new VEXnet Key 2.0.

Motor Ports: (8) standard 3-wire Motor or Servo ports. (2) 2-wire Motor ports.

I2C Smart Sensor Port: Will connect to multiple n

ew smart sensors in the future.

UART Fast Serial Ports: Connects to the VEX LCD Display (19,200 baud) and will have future support to 1.125 Mbaud

Digital/Analog Input Ports: (8) high-res Analog Inputs, (12) fast Digital I/Os that can be used as interrupts.

Rx1 and Rx2 Ports: Also support for two 75MHz crystal transmitters and receivers

Battery Ports: Connect 7.2V power sources, such as the Battery Holder or the VEX 7.2V Robot Battery. Also connect a 9V Backup Battery to protect against communication losses.

276-2192-vexnet--joystick-a

The VEXnet Joystick allows a human operator to control a robot in real-time using the VEXnet wireless link. The joystick has two 2-axis analog joysticks, 4 trigger buttons and two 4-button directional pads. It also has an accelerometer that provides X-Y tilt outputs. This allows you to control an arm or drive system by changing the orientation of the joystick (tilting). Just plug a VEXnet USB Adapter Key or new VEXnet Key 2.0 into the port on the back and enjoy the ultimate in robot control.
