1. A subsea electronics module (SEM) to provide control functions for a subsea control module (SCM) for a subsea well installation, the SEM comprising:
- a housing enclosing components of the SEM defining an SEM housing, the SEM housing having a circular cross-section;
at least two printed circuit boards enclosed within the SEM housing and having control circuitry provided thereon configured to perform certain dedicated functions for controlling a subsea control module of a subsea well installation, the printed circuit boards arranged in parallel in a stack;
a communications handling board enclosed within the SEM housing and operatively connected to the printed circuit boards, the communications handling board being arranged to lie in a plane orthogonal to the stack of printed circuit boards; and
a communications component for enabling communication between the printed circuit boards, the communications component being mounted on the communications handling board, the communications component comprising an Ethernet switch positioned on a surface of the communications handling board facing an inner surface of the housing between the respective surface of the communications handling board and the inner surface of the SEM housing, adjacent the inner surface of the housing to provide direct heat export to the SEM housing.
