AI Design Reviews

AI Design Reviews thumbnail
Whenever I ask for a design review, I need you to test each of these individual aspects one by one:
  • All reset/enable have an external pull-up or pull-down resistors
  • None of the floating pins require pull-up or pull-down resistors
  • All resistor’s voltage rating is sufficient for the maximum voltage applied. If any resistor doesn't contain voltage rating please flag this clearly as an error.
