ECM-ASL3

Series: ECM

Manufactured byAvalue

The Avalue ECM-ASL3 is a 3.5-inch industrial micro module SBC with a top-layer soldered-down Intel processor, supporting the Intel Processor N97, Intel Core i3-N305, and Intel Atom x7000RE series. It pairs a single DDR5 4800MHz SO-DIMM socket (up to 16GB) with onboard TPM 2.0 security and a wide DC +9V to +36V input, making it a compact, rugged compute core for embedded HMI, edge, and industrial control designs. The ECM-ASL3 drives triple independent display through HDMI 2.0b, DisplayPort 1.4 (both up to 4096x2160 @ 60Hz) and an LVDS/eDP channel, and delivers strong networking with two Intel I210 Gigabit and one Intel I226 2.5GbE ports. Triple M.2 expansion (Key-B with 5G/WWAN+GNSS SIM support, Key-E for Wi-Fi, Key-M for NVMe/SATA storage) plus SATA III gives integrators flexible storage and wireless options in a board-level form factor running Windows and Linux.
