Avalue EPX-EHLP 2.5" Pico-ITX SBCs with Intel Elkhart Lake, 2.5GbE and 4K DisplayPort

Some embedded designs leave only a palm-sized space for the computer, yet still need a proper memory socket, two networks and a 4K display. The Avalue EPX-EHLP series fits that space: a 2.5 inch Pico-ITX SBC, also called a Pico-ITX motherboard, measuring 100 x 72 mm, with the Elkhart Lake processor mounted on the underside of the board. The connectors sit along one edge, so the board can mount flat behind a panel with its I/O facing out.

Every EPX-EHLP shares the same board. One 260-pin SO-DIMM socket takes up to 32 GB of DDR4-2666, which is unusual at this size. Intel UHD Graphics drive a dual-deck DisplayPort, one DP and one DP++, to 4096 x 2160 at 60 Hz, plus a single-channel 18/24-bit LVDS at 1920 x 1080 for a built-in panel. I/O covers one 2.5GbE port on an Intel i226 and one Gigabit Ethernet port on an Intel I211, two USB 3.1 Gen2 ports at the edge plus four USB 2.0 on headers, one RS-232 and one RS-232/422/485 port, and 4-bit GPIO. One M.2 B key (2242/2260) takes an SSD, with signal options of SATA III plus USB 3.1 Gen1, PCIe x1 plus USB 3.1 Gen1, or PCIe x2 by OEM BIOS request. Hardware monitoring watches temperature and voltage with automatic throttling, and a hardware watchdog resets the board if software stops responding.

The series differs in processor. The EPX-EHLP-J6412-A1R carries a Celeron J6412 and the EPX-EHLP-J6413-A1R a Celeron J6413, both from the Celeron J Series. The EPX-EHLP-X13E-A1R carries an Atom x6413E from the Atom x6000E Series, which adds IBECC in-band error correction on standard memory. The wide-temperature version names Intel i226IT and I211IT controllers for its LAN ports and a CH7511B-BFI converter for LVDS. The I/O is the same on all three builds, so a design can change processor without changing its cabling.

Power is a single 12 V DC input with AT and ATX modes, which keeps the power design simple in a small enclosure. Operating humidity is up to 95% at 40 °C, non-condensing, and the AMI BIOS sits on 256 Mbit SPI flash. Each board weighs 0.3 kg. The operating temperature range depends on the processor fitted, so ask us to confirm it for your build.
