Portwell has recently launched PEB-2274, a 3.5-inch fanless SBC built around Intel Atom x6425E Elkhart Lake SoC. Key features include up to 32GB DDR4 memory, two Gigabit Ethernet ports, three M.2 sockets for storage and expansion, and a wide 9V to 36V DC power input. Additionally, it has various display interfaces (HDMI, DP, LVDS), multiple serial ports, USB, and audio options.
We have already covered several other 3.5-inch inch Elkhart Lake SBCs with dual Ethernet ports including the Avalue ECM-EHL 3.5-inch SBC, Congatec Conga-PA7 Pico-ITX board, the iBase IB836 3.5-inch SBC, and the AAEON GENE-EHL5 SBC. All these boards support dual Ethernet and some of them have support for triple ethernet ports. But what’s unique about the PEB-2274 is that it has dual GbE ethernet, triple display, and a design specifically for industrial applications.

After taking a good look at the board I found that the board has a physical SIM slot present, but the company does not mention that on the specification table on the website or their datasheet. Usually from a board like this, you will get specifications like Wake-on-LAN, Watchdog timer, multiple indicator LEDs, fan header, and BIOS specifications but all this information is also not available on the spec sheet.
The Intel Atom x6425E SBC has a compact and fanless design which makes it suitable for edge computing applications like industrial automation, panel PC, kiosks, and digital signage applications. There’s no word about supported operating systems, but Portwell normally offers support for Windows, Linux, and in some cases VxWorks.
Portwell did not provide pricing or availability information for the 3.5-inch fanless SBC. but you may be able to find a few more details on the product page for the PEB-2274 which also includes a datasheet with more technical information.
