Title: Improve analog layout
Post by: 68tjs on Jul 29, 2013, 02:37 pm
1) add an inductor between Vcc and Avcc -> see Atmel Documentation

2) As Aref pin from the board output connector  can't be move because existing shields, Aref link have to be improve.
  A) add a 100nF capacitor as close as possible from the microcontroller
  B) insert an inductor in the link between the microcontroller pin  and the Aref output board connector. This will make  a filter with the existing capacitor.
