3.5-inch Elkhart Lake SBC offers triple GbE ports

Feb 24, 2021 — by Eric Brown 2,109 views

Ibase’s -40 to 85°C ready “IB836” SBC runs Ubuntu or Windows on an Atom x6000 with up to 32GB DDR4, 3x GbE, 3x USB 3.1, DP, Type-C with DP, 2x SATA, mini-PCIe, and M.2.

Avalue revealed the first 3.5-inch SBC based on Intel’s Elkhart Lake back in September with its ECM-EHL, and now Ibase has posted a preliminary product page for its own 3.5-inch entry. The IB836 offers triple 1GbE ports instead of the GbE and 2.5GbE ports found on the ECM-EHL or the dual GbE ports on Congatec’s smaller, Elkhart Lake based Conga-PA7 Pico-ITX board.

Elkhart Lake runs on 10nm SuperFin Tremont CPU cores and up to 32EU Intel Gen11 graphics with triple 4K. The SoC offers improved AI performance over the earlier, Atom-class Gemini Lake, which Ibase used on its 3.5-inch IB822 SBC.

Elkhart Lake integrates an Intel Programmable Services Engine (Intel PSE) built around a Cortex-M7 with features including remote out-of-band (OOB) and in-band (INB) device management. (For more details, see our Elkhart Lake report.)


Ibase is offering major IB836 SKUs with the quad-core Atom x6425E and x6413E and the dual-core Atom x6211E. However, it also supports other models including Pentium and Celeron Elkhart Lake SoCs. No OS support was listed by Ibase, but Intel’s IB836 promo page says it runs Ubuntu and Windows.

Aside from their different Ethernet configurations, the Ibase and Avalue boards differ in how they deal with storage and expansion. The IB836 offers dual SATA interfaces, one of which colays with an optional mSATA drive available on the mini-PCIe slot. By contrast, Avalue’s ECM-EHL has a single SATA connection plus mSATA available on an M.2 B-key slot. Both boards also provide an M.2 E-key for WiFi/Bluetooth.

The IB836 enables triple independent displays via a DisplayPort plus a second DP available via USB Type-C and eDP or LVDS. Avalue’s board instead offers triple displays with HDMI, DP, eDP, and LVDS options. Whereas Avalue’s board supplies dual USB 3.1 Gen2 and dual USB 2.0 host ports, Ibase gives you 3x USB 3.1, which is presumably the slower Gen1, plus the Type-C port.

Other features common to both boards include a COM port, DIO, TPM, and a 9-36V input. Ibase provides standard -40 to 85°C support on the Atom-equipped models whereas this is optional with Avalue. Ibase supports error-correcting IBECC RAM, but this is not listed by Avalue.
