Next Unit of Computing (NUC) is a small-form-factor (SFF) PC designed by Intel and is based on soldered-on low-power Celeron, Pentium, i3, i5 and i7 CPUs. Its motherboard measures 4 × 4 inches (10.16 × 10.16 cm).
The barebone kits consist of the board, in a plastic case with a fan, an external power supply and VESA mounting plate. Intel does offer for sale just the NUC motherboards, which have a built-in CPU, although (as of 2013) the price of a NUC motherboard is very close to the corresponding cased kit; third-party cases for the NUC boards are also available.
Follow usual installation guide procedures.
It is highly recommended to update the board BIOS prior to installation. See official Intel BIOS update instructions for details.
Intel NUCs support NVMe drives connected to the PCIe M.2 connector. See Solid State Drives/NVMe.
Most NUC wireless adapters should work out of the box. Make sure relevant firmware is loaded. See Wireless network configuration#iwlwifi for details.
Some NUCs have LEDs which can be controlled by software by installing the kernel driver . To use this, Software Control must be enabled in the BIOS Power settings.AUR
Fastest boot times are achieved with UEFI boot and disabling legacy boot in the BIOS settings.
If you want to use 4K graphic output, open the BIOS settings and set Devices and Peripherals -> Video -> IGD Minimum Memory to 512 MB and IGD Aperture Size to 1024 MB.
The PulseAudio#Switch on connect module is buggy and in some cases might cause PulseAudio to stop playing audio when disconnecting the plug, until pulse is restarted. In this case, comment out the module:
Hades Canyon NUC - No External Microphones
External microphones being plugged into the front or back 3.5mm jack may not appear in PulseAudio (only the Internal Microphone array will be used).
To fix this, create
/etc/modprobe.d/alsa-base.conf and add this:
options snd-hda-intel model=dell-headset-multi
Reboot the device, and three new input devices should be listed under Input Devices, Built-in Audio Analog Stereo - Internal Microphone, Headset Microphone, and Microphone.
For some NUC devices the Intel specification shows that TPM is not available but often those devices are actually capable of TPM 2.0 features through a firmware based implementation called Intel PTT. Storing and retrieving values is working as you would expect from a TPM chip.
After issuing a shutdown, the NUC might remain in some state which is not completely shut down, as indicated by a remaining blue power LED. In this case it's neccesary to power off the unit by holding the power button for a few seconds.
The workaround for this issue is to disable all wake-on-CIR (infrared sensor) options in the BIOS. In some cases it might be required to disable the CIR sensor completely to fix the issue.
