* Power Reduction can be enabled (Active High). Refer to the HobbyCNC PRO manual for details.
** The actual function of these pins is determined in your CAM software.
*** Pins are made available via solder pads. Nothing is done to these lines on the PRO board. Straight from the D connector to the solder pads at P6.
