Avalue EPI-ARLS 4-inch EPIC SBC features LGA1851 socket for Intel Core Ultra Arrow Lake-S processors

Avalue EPI-ARLS is an Intel Core Ultra-based industrial SBC in a 4-inch EPIC (Embedded Platform for Industrial Computing) form factor. Compared to other EPIC SBCs like AAEON EPIC-ADN9, AAEON EPIC-TGH7, and VIA VAB-950, this one comes with an LGA1851 socket supporting desktop-class Arrow Lake-S CPUs, up to 35W TDP.

The board supports up to 48GB DDR5-6400 via a single SO-DIMM socket, triple display output (DP 2.0, HDMI 2.0, LVDS/eDP), and up to 3x 2.5GbE ports. Additionally, it features USB 3.2, USB 2.0, COM ports for communication, TPM 2.0 for security, GPIOs, and ALC888S codec for audio. Expansion options include M.2 E-Key for Wi-Fi and dual M.2 M-Key for storage. It runs on 12V DC, supports AT/ATX mode, and comes in Q870 (3 LAN, 3 M.2) and H810 (2 LAN, 2 M.2) variants.
