Onboard USB Header Information for Intel® NUC
USB headers on most motherboards use a standard 2.54mm pitch (as measured from pin center to pin center). However, due to the limited space on Intel® NUC motherboards, Intel® NUC onboard USB headers use smaller pitches of 1.25mm or 2.0mm.
See the Connectors and Headers section of the Technical Product Specifications for Intel® NUC Products for the following information:
- Location of the headers on the motherboard
- Molex connector part number
- Pin and signal information
The table shows the different types of USB headers used on Intel NUC products.
| USB header type | Image |
| Blue dual-port USB 3.0 |  |
| White single-port USB 2.0 |  |
| White dual-port USB 2.0 |  |
| Black dual-port USB 2.0 |  |
The onboard USB headers can be used to:
- Connect to specialty lids or backpanel extensions
- Connect from an Intel NUC motherboard-only SKU to a connector on a 3rd party chassis
If the USB device you plan to connect to the onboard header uses the standard 2.54mm pitch, you'll need an adapter cable with a 1.25mm or 2.0mm pitch connection. Look for adapters described as follows:
- 2.54mm to 2.0mm pitch USB port header adapter cable
- 2.54mm to 1.25mm pitch USB port header adapter cable
