+Supported Boards

+The board support code is only used for self-contained examples and testing. It is not used when TinyUSB is part of a larger project.
+It is responsible for getting the MCU started and the USB peripheral clocked with minimal of on-board devices

+-  One LED : for status
+-  One Button : to get input from user
+-  One UART : needed for logging with LOGGER=uart, maybe required for host/dual examples
