I just put a few dots on the possible soldering points, The green dots are for AGND, pink for AVDD. With a very fine tip soldering iron, soldering pads of existing components can be utilized. , otherwise just scrape off the soldering mask to expose the copper if needed.
Can you elaborate on the highlighted? Wow these are tiny for soldering. I guess you have to use a magnifier to find the spot for soldering.
BTW, FYI I have been testing a Crucial 480GB mSATA on a ipod 5.5g using your patch. So far I have copied about 365 GB of files to the drive without any issue. No heat issue no slowing down and ipod very responsive. The battery seems performing very well too. Your patch works like a charm. Thanks a ton on this.
