6 On-board LEDs
The board offers two LEDs in order to indicate board status. The function of both LEDs is dependent on
the firmware version. With standard TMCL firmware the green LED should be flashing 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.
