ASRock Industrial NUC-J6426 4×4 Motherboard with Quad-Core Intel Elkhart Lake J6426 and Dual 4K Display

Compact systems that run a browser-based HMI or a local database benefit from the fastest processor in a low-power family, without growing the board or the power supply. The NUC-J6426 is ASRock Industrial’s 4×4 motherboard with the quad-core Intel Elkhart Lake J6426. Also called a NUC motherboard, it measures 104 x 102 mm and shares the NUC 6000 datasheet with three sister boards.

The J6426 is an Elkhart Lake SoC running at up to 3.0 GHz within 10 W, which keeps heat and power draw low for always-on equipment. Two 260-pin DDR4-3200 SO-DIMM sockets run in dual channel for up to 32 GB. Intel Gen 11 Graphics drives two independent displays through HDMI 2.0b and DisplayPort 1.2 (DP++), each at up to 4096 x 2160 at 60 Hz, which suits a local screen plus a second monitor or signage output.

I/O covers two Gigabit Ethernet ports on Realtek RTL8111G-CG or RTL8111H-CG controllers, four USB 3.2 Gen2 ports (two Type-A, two Type-C) and four USB 2.0, two of them on an internal header. One RS-232/422/485 port on an internal header links serial equipment. An M.2 Key M socket (2242/2260/2280) with PCIe x1 and SATA3 takes an SSD, a SATA3 port adds a second drive, and an M.2 Key E 2230 socket with PCIe x1 and USB 2.0 is free for expansion. The NUC-J6412 is the same board with the J6412 at up to 2.6 GHz, and the NUC-N6415 pairs a 3.0 GHz quad-core with a 6.5 W rating.

Power is 12 to 19 V DC on a DC jack, with AT and ATX power-on modes. The NUC-J6426 operates from 0 to 60 °C and can be stored from -40 to 85 °C at 5 to 90% humidity. TPM 2.0 is onboard, and a watchdog timer with 256 steps from 0 to 255 seconds resets the system if software hangs. Realtek ALC233 audio feeds a front headphone and microphone jack, with an internal line-in/out header shared with it. The board stands 36 mm tall.
