    GPIO Drive Current Spec


      What is output driving capability of Gen2? Product Brief says, it's been *improved*:

      • 12 GPIOs fully native for greater speed and improved drive strength.

      But, there isn't specific number (I'm waiting for Data Sheet).

      If I read the schematic, GPIO13, for example, is driven by SN74LV125A which has following capability:

      • +-16mA @5V
      • +-8mA @3.3V.

      These are recommended ratings. Maximum rating is +-35mA.

      Above is *different* from Gen1 which was:

      • 10mA source / 25mA sink @3.3V or 5.5V


      Has it been improved or simply changed?
