"""Representation of an Mbed-Enabled Development Board.
Attributes:
board_type: Type of board in format that allows cross-referencing with target definitions.
board_name: Human readable name.
product_code: Uniquely identifies a board for the online compiler.
target_type: A confusing term that is not related to 'target' in other parts of the code.
Identifies if a board in the online database is a `module` or a `platform` (modules are more
complex and often have supplementary sensors, displays etc. A platform is a normal development board).
slug: Used with target_type to identify a board's page on the mbed website.
build_variant: Available build variants for the board.
Can be used in conjunction with board_type for referencing targets.
mbed_os_support: The versions of Mbed OS supported.
mbed_enabled: Whether Mbed OS is supported or not.
