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
