Nexcom EBC 358X 3.5" Elkhart Lake SBCs Rated -40 to 80 °C with Cooler Kit

Roadside and trackside equipment such as traffic signal controllers, speed cameras and railway gates sits in outdoor cabinets through every season, and the board inside has to run on the supply the cabinet provides. The Nexcom EBC 358X series is the extended-temperature version of the EBC 358: a 3.5 inch SBC on Intel Atom x6000E Elkhart Lake processors, rated from -40 to 80 °C at board level with the EBC358X cooler kit fitted.

Every EBC 358X shares the same layout. One DDR4-3200 non-ECC SO-DIMM socket takes up to 32 GB, and integrated Intel UHD graphics drive VGA at up to 1920 x 1080 at 60 Hz, HDMI 1.4b at up to 3840 x 2160 at 30 Hz and dual-channel 18/24-bit LVDS at up to 1920 x 1080 at 60 Hz. I/O covers two Gigabit Ethernet ports on Intel I210-IT controllers, two USB 3.2 Gen 1 and four USB 2.0 ports, four serial ports including RS-232/422/485, 8-bit digital I/O, a watchdog timer, onboard TPM 2.0 and HD audio. A full-size mini-PCIe slot and an M.2 3042 Key B socket each have a nano-SIM slot, and storage is one SATA 3.0 port.

Three builds are offered, all as barebones. The EBC 358X carries the quad-core Atom x6425E at 2.0 GHz base, up to 3.0 GHz and 12 W. The EBC 358X-6413E has the quad-core Atom x6413E at 1.5 GHz and 9 W, and the EBC 358X-6211E the dual-core Atom x6211E at 1.3 GHz and 6 W. The lower-wattage builds put less heat into a sealed cabinet, which matters when the enclosure sits in direct sun, and all three keep the same I/O and connector positions.

Power is 12 V or 24 V DC only, detected automatically, on a 4-pin (2 x 2) ATX connector, with AT and ATX modes. Storage temperature is -40 to 85 °C and operating humidity 10 to 95%, non-condensing. The board measures 146 x 105 mm and meets CE and FCC Class A. Nexcom names energy and environment, traffic signal control and monitoring, speed cameras, railway gates, MRT ticket vending machines and charging stations as target markets, along with outdoor systems, home automation and thin clients.
