Core Modules
These core modules are intended on being consistent across ports and boards.
A module may not exist on a port/board if no underlying hardware support is
present or if flash space is limited. For example, a microcontroller without
analog features will not have analogio. See the Module Support Matrix - Which Modules Are Available on Which Boards page for
a list of modules supported on each board.
