ASRock spins Whiskey Lake-U in thin Mini-ITX, 3.5-inch, and NUC formats

Apr 22, 2019 — by Eric Brown 2,995 views

ASRock announced four products based on Intel’s 8th Gen Whiskey Lake-U: a thin Mini-ITX “IMB-1216” board, a 3.5-inch “SBC-350,” and a NUC 4×4 form-factor “iBox-8365U” mini-PC and NUC-8365U mainboard.

ASRock Industrial has been busy lately tapping the latest embedded-oriented x86 chips in products such as the Intel 8th Gen Whiskey Lake-U based iBox-8265U mini-PC, as well as the iBox-R1000 industrial PC and NUC-R1000 mainboard built around the AMD Ryzen Embedded R1000. Now it has announced four more Whiskey Lake-U products aimed at the embedded market.

The IMB-1216 thin Mini-ITX board and 3.5-inch SBC-350 boards both run the quad-core, dual-threaded Core i5-8365U, which clocks at 1.6GHz (4.1GHz Turbo). This newly added model has a higher Turbo boost rate than the up to 3.9GHz i5-8265U.

The iBox-8365U mini-PC and the separately available NUC-8365U board that drives it similarly feature the i5-8365U in a BGA 1528 package, but also support the 1.8GHz (4.6GHz Turbo), quad-core Core i7-8565U and the dual-core, 1.8GHz (3.9GHz Turbo) Core i3-8145U. Like the i5 model, these are both dual-threaded and offer Intel Gen9 UHD Graphics 620 with 24 EUs and a 15-25W TDP.


ASRock’s announcement mentions only Windows 10. However, the AnandTech post that alerted us to the IMB-1216 lists Linux support, as does the iBox-8365U datasheet. Like ASRock’s earlier iBox-8265U mini-PC, the iBox-8365U runs Linux 2.6, which we imagine is available for all these Whiskey Lake systems. All four products support up to up to 32GB of dual-channel, 2400MHz DDR4, including ECC RAM.


The IMB-1216 joins Congatec’s Conga-IC370 among early thin Mini-ITX boards running Whiskey Lake. The IMB-1216 similarly offers a 170 x 170mm Mini-ITX footprint with a low profile. It supports industrial applications with a semi-extended 0 to 60°C range and offers a choice of 12V or 19-28V DC inputs with an AT/ATX switch.

The IMB-1216 is equipped with 2x Gigabit Ethernet ports (Intel and Realtek) and 2x SATA III ports, as well as a SATA power output. Unlike the iBox-8365U, it leverages the Whiskey Lake support for USB 3.1 — it offers 4x USB 3.1 host ports and a fifth internal 3.1 interface. Three USB 2.0 headers are also available along with 2x RS232/422/485, 3x RS-232, and 8x GPIO interfaces.

Triple M.2 slots are available. There’s a Key-M (2242/2260/2280) socket with PCIe x4 or SATA III, as well as a Key-E (2230) with PCIe x1, CNVI, and USB 2.0 support, which is primarily designed to run a WiFi/Bluetooth card. You also get a Key-B (3042) with USB 2.0 for 4G, which is accompanied by a SIM slot.

Triple displays are supported via 4K-ready HDMI and DP++ 1.2 ports and internal VGA and LVDS (or eDP) headers. Other features include dual audio jacks and a speaker header. You also get a watchdog and TPM security.


No image was provided for the SBC-350, which joins Congatec’s Conga-JC370 among early 3.5-inch Whiskey Lake boards. The board provides a 0 to 60°C range and offers either a 12V or 12-36V input with an AT/ATX switch.

The SBC-350 provides 2x Intel-based GbE ports, 2x DisplayPorts, and 4x USB 3.1 ports on the coastline. Internal features include an LVDS interface, which helps support triple simultaneous displays, and a SATA III port. You also get 4x USB 2.0, 4x RS232/422/485, and 4x in/4xout GPIO.

The SBC-350 provides both a Key-M (2242/2260/2280) socket for storage and a Key-E (2230) for wireless. You also get speaker, TPM, and SATA power headers.

iBox-8365U and NUC-8365U

The iBox-8365U mini-PC, which was briefly mentioned in the announcement of the earlier iBox-8365U, is much like the Ryzen R1000 based iBox-R1000, which similarly adopts the 4×4, or as ASRock calls it, 4″x4″ NUC form-factor. There were no details on the separately available NUC-8365U, but this appears to be the board inside the iBox-8365U.

The 171.8 x 150 x 71.5mm, 2.2 kg system ships with an active heatsink that ASRock calls a “fansink,” and supports 0 to 50℃ temperatures. There’s a standard 12V DC input and Kensington Lock support.

The iBox-8365U is equipped with a 2.5-inch SATA III bay and 2x GbE ports (Intel and Realtek). Triple displays are enabled via 2x DP and a single HDMI port. Additional features include 3x USB 3.1 ports and a DB9 port with RS232/422/485. There also appears to be a USB 2.0 port on the front of the unit.

Internal interfaces include a second USB 2.0, 2x RS-232, and an audio header. A watchdog is also on board.

Further information

No pricing or availability information was provided for the “preliminary” IMB-1216, iBox-8365U, and NUC-8365U or the “coming soon” SBC-350. More information may be found in ASRock Industrial’s announcement, as well as its IMB-1216, SBC-350, and iBox-8365U product pages.
