Cuttable traces on the dual MC33926 motor

driver shield for accessing nD2 and nSF

separately on each driver IC.

The following diagrams shows the relevant sections of the board schematic:

To separately access both the pins, you can use a knife to cut the trace between the through-hole pair.

For D2, note that once the connection between the two pins is severed, only M1D2 will have the protection resistor
between it and the logic connections.

For SF, note that once the connection between the two pins is severed, only M1SF will have the required pull-up
resistor and the protection resistor between it and the logic connections; you will need to add a separate pull-up
resistor and protection resistor for M2SF.
