LED Indicators

The MegaMoto has three LEDs used for visual indication of the state of the unit. The Enable

LED is red and when lit shows that the power chips are enabled. The green PWMA/B LEDs

show the presence of an input signal to the power chips. The brightness of the PWMA/B

LEDs will vary with the duty cycle of the input signal. Note, these LEDs reflect the state of the
