How does one interpret the LEDs on the VMX Robotics Controller?
The following table explains the meaning of the LEDs on the VMX Robotics Controller
| Condition | S1 (Green) | S2 (Green) | 3.3V (Green) | Fault (Red) | CAL (Orange) | CAN Status |
|---|---|---|---|---|---|---|
| Startup (1 second) | On | On | On | Off | On | Off |

| Gyro Calibration | On | On | On | Off | Slow Flash | On |
| Normal | On | On | On | Off | Off | On |

- Note: If the S1 LED is off during Gyro Calibration or Normal State, this indicates interrupts are not being received from the navX-sensor.
- Note: If the S2 LED is off at any time except briefly after Startup, this indicates a problem communicating to the navX-sensor over the internal I2C bus.
- Note: If the Fault LED is on at any time, this indicates a short between one of the external power and ground pins.
