3.5-inch Tiger Lake SBC Offers Quad Displays, 2.5GbE

Written by Eric Brown

Commell’s 3.5-inch “LE-370” SBC features a Tiger Lake UP3 CPU with up to 32GB DDR4, GbE and 2.5GbE ports, quadruple displays, 4x USB 3.2 Gen2, 2x M.2, and mini-PCIe.

Commell was one of the first companies to announce a Pico-ITX board with Intel’s 11th Gen Tiger Lake UP3 platform with its LP-179 SBC and has now followed up with a larger, 3.5-inch board. The LE-370 follows other 3.5-inch Tiger Lake boards including Ibase’s IB953, Aaeon’s GENE-TGU6, and Kontron’s 3.5”-SBC-TGL.

The LE-370 supports any Tiger Lake UP3 embedded “E” variant, as well as the industrial-focused ”GRE” models, which add TSN, Intel TCC, and functional safety (FuSa) features. The SBC defaults to the quad-core Core i7-1185G7E and dual-core Celeron 6305E. No OS was listed, but Linux or Windows should do the job. Other 3.5-inch Commell SBCs include the Whiskey Lake based LE-37N and Coffee Lake powered LS-37L.

Unlike the 3.5-inch Tiger Lake SBCs from Aaeon, Ibase, and Kontron, the SBC is limited to 32GB DDR4 instead of 64GB. Otherwise, the board is highly competitive. Like Aaeon’s GENE-TGU6, you get 4x USB 3.2 Gen2 ports for up to 10Gbps throughput, and like the Aaeon and Kontron entries, you get both 1GbE and 2.5GbE ports.

The LE-370 lacks the M.2 B-key slot with SIM support of the Ibase and Kontron boards. However, you get an M.2 E-key for WiFi, M.2 M-key with PCIe Gen4 for NVMe, mini-PCIe with mSATA, and dual SATA III interfaces.

Like the other boards, Commell’s entry provides quadruple simultaneous display support, in this case via DP, HDMI, VGA, and LVDS. The SBC is further equipped with various serial, USB, GPIO, audio, and other headers. The board is powered by a 9-35VDC input and offers a watchdog and RTC.
