2.4 Antenna Connection
The NUC 8 Essential/Pro Compute Element wireless module does not have any antennas
connected. For wireless and Bluetooth operation appropriate antennas will be required.
Depending on the enclosure design internal or external antennas can be supported. Figure 6
shows the location of the two antenna connectors on the Mylar side.
Figure 6. Location of the Antenna Connectors
The wireless module uses a standard 2x2 mm size RF micro coaxial receptacle (connector) with an
outer diameter of 1.5 mm as defined in the PCI-E M.2 Specification. Specific plugs should be
selected to suit the assembly allowable mating height and cable diameter. Refer to the PCI-E M.2
Specification for the minimum requirements of the compatible RF connectors and mating plugs.
• Receptacle physical outline is 2mm x 2mm x 0.6mm
• Receptacle outer diameter is 1.5mm
2.5 BIOS Security Switch
Figure 7 shows the location of the BIOS Security Switch. The 3-position switch determines the BIOS
Security program’s mode.
CAUTION
Do not change the switch with the power on. Always turn off the power and unplug the power cord
from the carrier board before changing a switch setting. Otherwise, the board could be damaged.

Table 8 lists the switch settings for the three modes: normal, lockdown, and
recovery/configuration.
Table 8. BIOS Security Switch Settings

Switch Setting
Configuration
Normal
A
The BIOS uses current configuration information and passwords for
booting.
Lockdown
B
The BIOS uses current configuration information and passwords for
booting, except:
• All POST Hotkeys are suppressed (prompts are not displayed and keys
are not accepted. For example, F2 for Setup, F10 for the Boot Menu).
• Power Button Menu is not available.
BIOS updates are not available except for automatic Recovery due to flash
corruption.
Recovery/Configuration
C
BIOS Recovery Update process if a matching *.CAP file is found. Recovery
Update can be cancelled by pressing the Esc key.
If the Recovery Update was cancelled or a matching *.CAP file was not
found, a Configuration Menu will be displayed. The Configuration Menu
consists of the following options:
[1] Suppress this menu until the BIOS Security Switch is set to normal.
[2] Clear BIOS User and Supervisor Passwords.
[3] Clear Trusted Platform Module (vPro SKU only)
Warning: Data encrypted with the TPM will no longer be accessible
if the TPM is cleared

2.6 Power
The Intel® NUC 8 Essential/Pro Compute Element requires a DC input from the carrier board via
the connector. The carrier board must be provide the proper voltage and current as listed below:
• Voltage: 5.7-20 V DC +/-5%
• Current (RMS max): 3.0-10.6 A
• Current (Peak): 12 A
CAUTION
It is strongly recommended to make sure that the carrier board power source is disconnected
before installing or removing the Intel® NUC 8 Essential/Pro Compute Element into the carrier
board connector. Installing or removing the Intel® NUC 8 Essential/Pro Compute Element while a
power source is connected to the carrier board may cause damage to the Intel® NUC 8
Essential/Pro Compute Element, operating system corruption, create a no boot condition or result
in data loss.

The following figures illustrate the mechanical form factor for the NUC 8 Essential/Pro Compute
Element. All dimensions are shown in millimeters (mm).

2.8 Thermal
The fundamental design of the Intel® NUC 8 Essential/Pro Compute Element relies on the carrier
board enclosure for proper cooling. Both internal components and external skin temperatures
are critical parameters in proper cooling, and should be considered in any design. For best
cooling performance, direct contact with a thermal management device to the bottom of the
Compute Element such as a heatsink or enclosure surface is recommended. This can be
accomplished with active or passive cooling design approaches. Non-contact convection only
cooling may be possible but will likely result in performance limitations or compromises in skin
temperature levels relative to a conductive design approach.
The Integrated Heat Spreader side of the Compute Element is the primary heat source. To
provide adequate cooling of the Compute Element while maintaining safe skin temperatures a
thermal solution that contacts the entire metal portion of the Integrated Heat Spreader is
recommended. Localized contact with the primary heat source on the Compute Element bottom
is not recommended as the location is subject to change with different generations of the
Compute Element. The Mylar side of the Compute Element does not typically require contact
with a thermal solution, however proper air flow over the top of the Compute Element is
recommended. The below information is critical for the design of a thermal solution.
• The Thermal Design Power (TDP) of the processors used in the NUC 8 Essential Compute
Element and the NUC 8 Pro Compute Element is 15W.
• The Power Limit 1 (PL1) default setting in the BIOS of the NUC 8 Essential Compute
Element and the NUC 8 Pro Compute Element is 15.
• The Junction Temperature Range (Tj) of the processor used in the NUC 8 Essential
Compute Element and the NUC 8 Pro Compute Element is 0C -100C.
• The TDP specification temperature range of the processor used in the NUC 8 Essential
Compute Element and the NUC 8 Pro Compute Element is 35C -100C
