Laird’s documentation for their RF modules does not include a breakdown for the ‘-SPB’ suffix on some of their RF modules. This can leave customers confused, and wondering whether ‘-SPB’ is compatible with the normal, suffixless part.
The manufacturer states that the -SPB calls out “spot buys”. This is a supplier internal information callout and does not have any effect on the part.
