Hi Alan: Use Rev B. Rev A of the instructions had an error that was corrected by an errata. Apparently you don't have that errata. The change was subsequently included in the Rev B printing.

I've come up against an issue that's causing me some confusion. The mod for the KPAIO3 consist of a small electrolytic capacitor soldered to two pins on the KPAIO3 module. I have two versions of instructions, one dated April 13 2016 - Revision A and the other dated August 10 2016 - Revision B. I presume that Rev B supersedes Rev A, so I should follow Rev B? The images on both sheets appear to show the KPAIO3A module, but describe the KPAIO3 module, so I presume for the purpose of modding they're the same, however the Negative lead of the new capacitor is shown going to different points on the module, depending which instruction sheet is viewed and looking at the trace layout on either, this doesn't make sense. Besides that, the trace layout on the module that I have is different to both of the paper descriptions. Can anyone shed any light on this conundrum or know if any addendum has been issued? 73, Alan.
