7 On-Board LEDs

The PANdrive™ offers two LEDs in order to indicate status. The function of both LEDs is dependent on the

firmware version. With standard TMCL firmware the green LED should be flashing slowly during operation and

the red LED should be off.

When there is no valid firmware programmed into the board or during firmware update the red and green

LEDs are permanently on.
