Hi Ron,

I just ordered my K3 on Thursday.  Do you know if this modification has already been phased in to new kits?

Hello David:

Wayne asked me to reply since I prepared the application note. Only two
resistors are needed, so if you've done the mod using the daughter board
locations Wayne originally mentioned, you're all set.

The version shown in the app note mimics what Aptos is doing as they modify
the boards in inventory. The resistors are in the same place electrically,
but they chose to put them on the main KIO3 board instead.

We followed that in the application note so it'd be easy to tell if the
modification has been made either in the field or at the factory.
