Avalue EPI-ARLS Intel Core Ultra 200S LGA 1851 4" EPIC Single Board Computers with Q870 or H810 Chipset and 2.5GbE

Some compact equipment needs socketed Intel Core processing in a smaller footprint than Mini-ITX. The Avalue EPI-ARLS series puts an LGA 1851 socket for Intel Core Ultra 200S T-series processors on a 4″ EPIC board measuring 165 x 115 mm, so an OEM can choose the processor per build and keep one board design across a product line.

The socket accepts the Core Ultra 5 225T, Core Ultra 5 245T, Core Ultra 7 265T and Core Ultra 9 285T from the Arrow Lake-S family, from 10 to 24 cores, all at a 35 W TDP, with AI performance rated at 13 TOPS. One 262-pin DDR5 SO-DIMM slot takes up to 48 GB at 5600 MHz, or 6400 MHz with Core Ultra 7 and Core Ultra 9 processors. Intel Xe LPG graphics drive DisplayPort 2.0 at up to 7680 x 4320 at 60 Hz, HDMI 2.0 at up to 4096 x 2304 at 60 Hz and an internal dual-channel LVDS or eDP panel at 1920 x 1080. A discrete TPM 2.0, a hardware watchdog and Realtek ALC888S audio with line-in, line-out and mic-in are on both boards.

Two chipsets set the range. The EPI-ARLS-H81-A1R uses the Intel H810 with two 2.5GbE ports, two USB 3.2 Gen 2 and two USB 3.2 Gen 1 Type-A ports and one M.2 M-key socket for an NVMe SSD. The EPI-ARLS-Q87-A1R moves to the Intel Q870, adding a third 2.5GbE port, four USB 3.2 Gen 2 Type-A ports, a second M.2 M-key socket in 2242 size and Intel AMT remote management through its I226LM port. Choose the H810 for single-drive, two-network builds and the Q870 for camera networks, a second SSD or remote fleet management.

Both boards share internal headers for four USB 2.0 ports, two RS-232 ports, two RS-232/422/485 ports and 16-bit GPIO. The M.2 M-key 2280 socket carries PCIe x4 Gen4 for NVMe or SATA SSDs, and an M.2 E-key 2230 socket with PCIe x2 Gen4 and USB 2.0 takes a Wi-Fi and Bluetooth module. Storage is M.2 only, with no SATA port on the board.

Power comes from 12 V DC on a barrel connector, with AT or ATX power modes. The board operates from 0 to 60 °C with its CPU cooler and 0.5 m/s airflow, and carries CE, FCC, UKCA and RoHS compliance. The EPI-ARLS series suits machine vision cells, operator panels, signage and compact industrial controllers where the processor choice may change from one product to the next.
