Avalue ECM-TGUC-15-A1R 3.5″ SBC with Intel Core i3-1115G4, PCIe Gen4 x4 M.2 and Six COM Ports

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 ECM-TGUC-15-A1R is the Core i3-1115G4 build in the Avalue ECM-TGUC series: a 3.5 inch SBC, also called a 3.5 inch motherboard, measuring 146 x 101 mm with the processor soldered on the bottom layer.

The Intel Core i3-1115G4 is an 11th Gen dual-core processor with 6 MB cache, set to 15 W in this ordering code. 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 18/24-bit LVDS at 1920 x 1080, which can be set to 2-lane eDP instead, for up to three displays at once.

Storage runs on an M.2 M key (2280) on PCIe Gen4 x4 and a SATA III port. An M.2 B key (3042/3052/2242) with SATA, USB 2.0, USB 3.0 and one SIM slot takes WWAN plus GNSS or an SSD, and an M.2 E key (2230) 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. The ECM-TGUC-35-A1R is the quad-core Core i5-1135G7 build, and the ECM-TGU series adds a third LAN port and a fourth display.

Power is 12 to 24 V DC with AT and ATX modes, AT by default. The board operates from 0 to 60 °C with 0.5 m/s airflow, stores from -40 to 75 °C, and is shock-tested to 10 G under IEC 60068-2-27 and vibration-tested to 1.5 Grms under IEC 60068-2-64. It weighs 0.2 kg, has TPM 2.0 on board, supports Windows 10 and Linux, and carries CE and FCC Class B marks.
