Electronic system assembly for electromagnetic interference reduction and electrical arcing protection

A system, comprising:

• an electronic system configured to generate a set of electronic signals;
• an interface including a plurality of connectors arranged along a surface of the interface, the interface electrically coupled to the electronic system;
• and
• an electronic system assembly, comprising:
• a first circuit board including a first set of electronic components;
• a first housing containing the first circuit board;
• a second circuit board including a second set of electronic components;
• a first connector shield having first sidewalls defining a first cavity, the first sidewalls having a first end abutting a first surface of the first circuit board and a second end abutting a second surface of the second circuit board;
• a first electrical connection extending through the first cavity and electrically coupling the first set of electronic components with the second set of electronic components;
• and
• a first interface connector physically and electrically coupled to the interface.
