@copilot Check that all reset/enable have an external pull-up or pull-down resistors. Report action items in an ordered list.

  1. SGP41_EN - This enable pin does not appear to have an external pull-up or pull-down resistor. Please add one accordingly.
  2. IC3 - This reset pin does not seem to have a pull-down resistor, Consider adding one externally.
  3. 1V8_EN - It appears that this pin does not have either a pull-up or pull-down resistor. Check the datasheet of the component it's connected to and add a resistor as needed.
  4. SCD41_EN - Similarly, this enable pin does not seem to have a pull-up or pull-down resistor. Please add an external pull-up or pull-down resistor.
  5. 3V3_EN - This enable pin does not have a pull-up or pull-down resistor. Please add one as needed.
  6. SHT40_EN - This enable pin seems not to be connected to any resistor. Consider adding an external pull-up or pull-down resistor.
For each enable/reset pin without a pull-up or pull-down resistor, verify the requirements based on the specific IC datasheet. Sometimes internal pull-ups/ pull-downs are provided.
