The VEX ARM® Cortex®-based Microcontroller coordinates the flow of all information and power on the robot. It has built in bi-directional communication for wireless driving, debugging and downloading using the VEXnet wireless link. The Microcontroller is the brain of every VEX robot.
ROBOTC for VEX Robotics v4.x
|Size||4.5in W x 3.9in L x 1in H|
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.
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.
