2.15 Connectors, Headers, and Expansion
CAUTION
Only the following connectors and headers have overcurrent protection: back panel USB, front
panel USB, internal USB headers, PCI Express Slots, and M.2 slots.
All other connectors and headers are not overcurrent protected and should connect only to
devices inside the computer’s chassis, such as fans and internal peripherals. Do not use these
connectors or headers to power devices external to the computer’s chassis. A fault in the load
presented by the external devices could cause damage to the computer, the power cable, and the
external devices themselves.
Furthermore, improper connection of USB header single wire connectors may eventually overload
the overcurrent protection and cause damage to the board.
This section describes the board’s connectors and headers. The connectors and headers can be
divided into these groups:
• Front panel I/O connectors
• Back panel I/O connectors
• Baseboard connectors and headers
• Interior chassis connectors and headers
• NUC Element Extreme board connectors and headers
