Avalue ECM-TGUC 3.5" 11th Gen Intel Core SBCs with PCIe Gen4 x4 M.2 Storage

An embedded controller that logs data locally needs fast storage and a mobile link as well as processing, all on a board that fits a small enclosure. The Avalue ECM-TGUC series is built for that job: a 3.5 inch SBC, also called a 3.5 inch motherboard, measuring 146 x 101 mm, with an 11th Gen Intel Core processor soldered on the bottom layer and a full-length M.2 2280 socket on PCIe Gen4 x4.

Every ECM-TGUC shares the same board. One 260-pin SO-DIMM socket takes up to 32 GB of non-ECC DDR4-3200. Tiger Lake UP3 Gen12 graphics drive two DP++ outputs to 4096 x 2160 at 60 Hz and a dual-channel LVDS at 1920 x 1080, which can be set to 2-lane eDP, for up to three displays. Storage runs on the M.2 M key and a SATA III port. An M.2 B key with SATA, USB 3.0 and one SIM slot takes WWAN plus GNSS or an SSD, and an M.2 E key takes Wi-Fi. I/O covers one 2.5GbE port on an Intel I225V and one Gigabit Ethernet port on an Intel I219LM, three USB 3.2 Gen 2×1 and five USB 2.0 ports, one RS-232/422/485 and five RS-232 ports, 8-bit GPIO and a Realtek ALC888S codec. TPM 2.0 is on board.

Two builds are offered, both at the 15 W setting. The ECM-TGUC-15-A1R carries a dual-core Core i3-1115G4 with 6 MB cache, and the ECM-TGUC-35-A1R a quad-core Core i5-1135G7 with 8 MB cache for heavier software. The I/O is the same on both, so a design can move from one to the other without changing its cabling.

Power is 12 to 24 V DC with AT and ATX modes, AT by default. The boards operate from 0 to 60 °C with 0.5 m/s airflow, store from -40 to 75 °C and handle up to 95% humidity at 40 °C, non-condensing. They are shock-tested to 10 G under IEC 60068-2-27, vibration-tested to 1.5 Grms under IEC 60068-2-64 and drop-tested to ISTA 2A. A hardware watchdog, temperature and voltage monitoring and ACPI 5.0 power states S0, S3, S4 and S5 are supported. Each weighs 0.2 kg, supports Windows 10 and Linux, and carries CE and FCC Class B marks.
