mainboardV3 version output driver differences ?

i noticed when looking at the output driver schematic on git hub and the schematic on the wiki, they are in fact different.
wiki version has:
2 driver lines paralleled for out_dcsw
1 driver line for out_pre
github version:
2 driver lines paralleled for out_pre
1 line driving a N-chanel fet (ap9t18gh) for out_dcsw
according to the uln2003 data sheet https://www.ti.com/lit/ds/symlink/uln20 ... e.com%252F "The collector-current rating of a single Darlington pair is 500 mA"
so the github version should handle directly driving a contractor drawing .36amps on ether the out_dcsw or out_pre ?

github:
i'll update the wiki once this is cleared up
