Increased feedback from your motors allows for more control.
Communicates via I2C via included 4-wire Cable.
Compatible with Flowol 4.
Firmware Bug Note:
We've recently discovered that some of our users are experiencing issues with their robot running after it is disabled. This error is due to a bug in the VEX Cortex Microcontroller firmware.
In very rare situations, the user processor inside the Cortex Microcontroller may encounter a partial reset (caused by a static shock, or intermittent power connection) while the master processor continues to operate normally. In this situation, the Cortex Microcontroller firmware could continue to send the last received command to the motor controllers, causing the motors to continue to run even if the robot has stopped communication with the joystick.
This error is rare, and very difficult to reproduce. We have identified that robots using the VEX Integrated Motor Encoders may be susceptible to this failure as the result of a static shock to the Cortex Microcontroller's I2C port. Users who experience such a failure should power-cycle their robots, which will reboot the Cortex processors and resume normal operation.
This bug is not something caused by user software programs. We are working to correct this issue with a firmware update in the coming months and apologize for any inconvenience this may have caused you.
Do not over-tighten screws when installing the Integrated Motor Encoder. Over-tightening can affect encoder performance.
Up to (8) I2C devices can be chained together and connected to (1) I2C port on the Cortex Microcontroller.
Compatibility: 2-Wire Motor 393.
