Intel NUC sports 5W Atom, offered as kit or SBC

Apr 24, 2014 — by Eric Brown 10,255 views

Intel announced a fanless mini-tower “NUC” mini-PC for thin clients, equipped with a 5-Watt Atom E3815 SoC and a new custom expansion interface.

The Linux-compatible Intel NUC Kit DE3815TYKHE is Intel’s first fanless member of its NUC (Next Unit of Computing) family of mini-PCs. The computer is also available as a single board computer (SBC) called the NUC Board DE3815TYBE.

Earlier Celeron-based

Like the recent NUC Kit DN2820FYKH, the DE3815TYKHE model runs on a 22nm-fabricated Bay Trail processor, but it’s an Atom E3815 instead of the earlier Celeron N2820. The E3815 is the power-stingiest of all the Bay-Trail-I processors, with a 5W TDP. It’s also the slowest, with a lone “Silvermont” architecture core clocked at 1.46GHz.

In addition to going fanless, the NUC Kit DE3815TYKHE is the first NUC to offer onboard flash storage (4GB eMMC) and the first to offer easy flat-panel connectivity via its Embedded DisplayPort (eDP) interface, says Intel. The computer is said to be the first NUC to include a VGA port, a watchdog timer, as well as serial port headers “for peripherals requiring the robustness of hardware handshaking,” says the chipmaker.


The new NUC also includes a new “Custom Solutions” connector offering I2C, PWM, GPIO, and other interfaces. The connector is designed “for interfacing with sensors and other embedded devices enabling the Internet of Things,” says Intel.

Unlike the squarish NUC Kit DN2820FYKH, the new NUC assumes a thin client like mini-tower form factor. Despite the lack of a fan, it’s considerably larger than the Celeron-based model, measuring 7.48 x 4.56 x 1.57 inches.

The device is designed as a thin client for schools, call centers, “and other locations with a large installed base of VGA monitors,” says Intel. It is also said to support light digital signage, point-of-sale, and kiosk solutions.

Like the Celeron-based NUC, you can load up to 8GB of DDR3L RAM on the system, which ships with 4GB of flash and a 2.5-inch SATA bay. Real-world ports include HDMI, VGA, and gigabit Ethernet ports, as well as an audio jack. There are also three USB ports, one of them a front-facing USB 3.0 port. Three more USB 2.0 interfaces are available internally along with the other expansion interfaces noted above.

A mini-PCI-Express slot is designed to support a wireless module, and the system offers built-in antennas. Other features of note include TPM support, an IR sensor, VESA mounting, and three-year availability.
