Nexcom X-300-H310 Mini-ITX Motherboard for 8th/9th Gen Intel Core with H310, Dual HDMI and LVDS

A socketed processor lets a kiosk or signage build choose its CPU to match the software, and change it later without a new board. The X-300-H310 is the H310 build in the Nexcom X300 series: a Mini-ITX motherboard with an LGA1151 socket for 8th and 9th Gen Intel Core processors, two HDMI outputs and an LVDS connector for a built-in panel.

Nexcom lists Core i3, i5, i7 and i9 processors from the 8th Gen Coffee Lake and 9th Gen Coffee Lake Refresh families, from the i3-8100T and i3-8300 to the i9-9900T, and all use the integrated Intel UHD Graphics 630. Two 260-pin DDR4-2400/2666 non-ECC SO-DIMM sockets take up to 32 GB. Two HDMI 2.0 outputs run at up to 4096 x 2160 at 60 Hz and a dual-channel LVDS connector drives a panel at up to 1920 x 1200 at 60 Hz, for three displays in total.

I/O covers two Gigabit Ethernet ports on Intel i219-LM and i211-AT controllers with PXE boot and wake on LAN, four USB 3.0 ports on the edge, four USB 2.0 on headers, one RS-232/422/485 and two RS-232 ports on JST connectors, 4-in/4-out GPIO, Realtek ALC3251 audio with line-out and mic-in, a watchdog timer and an onboard TPM 2.0 IC. Storage is an M.2 2280 Key M socket for a SATA SSD, and an M.2 2230 Key E socket takes a Wi-Fi and Bluetooth module; the LVDS connector takes the place of the PCIe x16 slot on this build. The X-300-Q370 is the Q370 build with three HDMI and PCIe x16, and the X304 moves to 12th and 13th Gen Core in an LGA1700 socket.

Power is +12 V DC only, through a DC jack on the edge or a 4-pin right-angle connector, with AT or ATX mode set by jumper. The X-300-H310 operates from 0 to 60 °C and handles humidity up to 95%, non-condensing. The board measures 170 x 170 mm in the standard Mini-ITX size, with a matching CPU cooler available. It meets CE under EN 55032 and EN 55024 and carries an FCC Class A mark under Part 15B.
