Avalue ECM-TGU 3.5" SBCs with 11th Gen Intel Core, Four Displays and Three LAN Ports

A multi-screen HMI or control cabinet often needs Core-class processing, several displays and a mix of network and serial ports on a board small enough for a compact enclosure, sometimes one that starts well below freezing. The Avalue ECM-TGU series covers that brief with a 3.5 inch SBC, also called a 3.5 inch motherboard, measuring 146 x 101 mm, with an 11th Gen Intel processor soldered on the bottom layer.

Every ECM-TGU 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 and eDP 1.3 to 4096 x 2160 at 60 Hz plus a dual-channel LVDS at 1920 x 1080, for up to four displays. I/O covers one 2.5GbE and two Gigabit Ethernet ports, four USB 3.2 Gen 2×1 and four USB 2.0 ports, two RS-232/422/485 and four RS-232 ports, 8-bit GPIO and a 92HD73C codec with a 3 W amplifier. An M.2 M key runs on PCIe Gen4 x4, an M.2 B key with SIM slot takes 4G or an SSD, an E key takes Wi-Fi and a SATA III port takes a drive. TPM 2.0 is on board.

The ordering code sets the processor and temperature range, all at the 15 W setting. Standard builds for 0 to 60 °C are the ECM-TGU-85-A1R with a Core i7-1185G7E, the ECM-TGU-45-A1R with a Core i5-1145G7E, the ECM-TGU-15-A1R with a Core i3-1115G4E and the ECM-TGU-6305-A1R with a dual-core Celeron 6305E. Wide-temperature W builds for -20 to 60 °C use GRE processors and Intel I225IT and I210IT LAN: the ECM-TGU-85W-A1R with a Core i7-1185GRE, the ECM-TGU-45W-A1R with a Core i5-1145GRE and the ECM-TGU-15W-A1R with a Core i3-1115GRE.

Power is 12 to 24 V DC with AT and ATX modes, AT by default. All builds operate 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 and ACPI 5.0 power states are supported. Each board weighs 0.2 kg, supports Windows 10 and Linux, and carries CE and FCC Class B marks.
