U403: change from 74LVC2G125 to 74LVC2G126 The two parts have the same footprint and pinout, but '126 3-state buffers have active-high OE inputs instead of active-low. The change is purely for software benefit: having GPIO 11/12 set to 1 correspond to that current contribution being enabled will be much more intuitive for developers and tinkerers.
