Description

If possible, we should make sure the 1.8V lines (high current / low voltage) as wide as possible. Examples are C16, C15, C12, C19 to SAM7, connection between C12 and C16, etc.

This makes the design more robust as the wider lines mean higher capacitance and less inductivity in case if high-speed current peaks.
