Notes :

  • For carrier or stand-alone boards use subsection for every connector type (add designator on description, not on the subsection title), for example:
    • SD
    • USB
    • ETH
    • FMC
    • ...
  • For modules which needs carrier use only classes and refer to B2B connector if more than one is used, for example
    • JTAG
    • UART
