Avalue EMX-EHLP-J12-A1-1R Quad-Core Intel Celeron J6412 Thin ITX Motherboard with 12 to 24 V DC Input and Dual 2.5GbE

An HMI panel, a signage player or a machine controller rarely needs four network ports, but it often needs a panel connection, serial lines and room for an SSD and Wi-Fi. The EMX-EHLP-J12-A1-1R is the two-port build in the Avalue EMX-EHLP series of Thin ITX motherboards, keeping the Celeron J6412 and the full serial and display set with two 2.5GbE ports in place of four.

Its Intel Celeron J6412 is a quad-core Elkhart Lake processor with a 10 W TDP, a good fit for HMI runtimes, browser-based dashboards, signage playback and control software. One DDR4 3200 MHz SO-DIMM slot takes up to 32 GB. Intel UHD Graphics drives HDMI 2.0b at up to 4096 x 2160 at 60 Hz, a DP++ output and an internal dual-channel LVDS connector, so the board can run an LVDS panel and two external screens at once.

Two 2.5GbE ports on Intel I226LM controllers connect the plant network and a device network. Two rear USB 3.1 Gen 2 and two USB 3.1 Gen 1 Type-A ports and four USB 2.0 headers take touch controllers, scanners and printers. Six COM headers, two RS-232/422/485 and four RS-232, plus 16-bit DIO connect PLCs, card readers and relays. An M.2 B-key takes a SATA SSD or a 4G module with its SIM slot, an M.2 E-key takes Wi-Fi and Bluetooth, and two SATA ports add drives.

The EMX-EHLP-J12-A1-1R runs from 12 to 24 V DC on a lockable barrel jack or a 4-pin connector and operates from 0 to 60 °C with 0.5 m/s airflow, with CE, FCC and RoHS compliance. Where a gateway needs four networks, the EMX-EHLP-J6412-A1R uses the same processor with four 2.5GbE ports, and the EMX-EHLP-X13E-A1R adds in-band ECC and -20 to 60 °C operation on an Atom x6413E.
