Cut the ‘CPU CS’ trace where the red line is placed.
The outlined areas marked in green are where you solder. However, the soldermask on the ‘CPU CS’ via
must be carefully scraped away to expose the copper. The ‘CPU INT’ has a pad conveniently placed and
does not require the soldermask to be scraped on its via.
