qualify such processes in combination with the SARA-N2 / N3 series modules before implementing
this in the production.

Grounding metal covers
Attempts to improve grounding by soldering ground cables, wick or other forms of metal strips
directly onto the EMI covers is done at the customer's own risk. The numerous ground pins should be
sufficient to provide optimum immunity to interferences and noise.
