3.5-inch Apollo Lake SBC supports industrial temperatures

May 24, 2018 — by Eric Brown 440 views

Ibase’s Linux-compatible, 3.5-inch “IB818” SBC provides a dual- or quad-core Apollo Lake SoC, plus 2x GbE, 4x USB 3.0, 2x SATA, 2x mini-PCIe, triple display support, wide-range power, and -40 to 85°C support.

Ibase doesn’t make a lot of SBCs, but it does offer some 3.5-inch models including the Intel Bay Trail Atom based IB897 and IB898. Now it has followed up with an IB818 model that advances to the recent Apollo Lake generation. Like these Bay Trail models, the IB818 supports an industrial -40 to 85°C range.

The IB818 is more like the IB897 in that it has dual GbE ports and dual mini-PCIe slots while the IB898 instead offers 1x GbE and 3x mini-PCIe. The product page download page shows only Windows 10 drivers, but the manual says the board also supports Ubuntu.

The 147 x 102mm IB818 joins a long list of Apollo Lake based 3.5-inch SBCs, but it’s the first one we’ve seen with -40 to 85°C support. Axiomtek’s CAPA312 offers up to -20 to 70°C support.


At first, we thought the QC and DC prefixes appended to the names of the supported Atom QC x7/ E3950, Pentium QC N4200, and Celeron DC N3350 SoCs referred to the industrial temperature versions. However, only the E3950 model, which is listed with “i-Temp support,” can run at -40 to 85°C. The Pentium and Celeron top out at 0 to 60°C.

The IB818 is intended for indoor or outdoor IoT, factory automation, self-service kiosk, and POS systems. The board offers a wide-range 12-24V DC input and operates at a typical +12V/1.09A.

The IB818 accommodates up to 8GB of RAM and offers dual SATA III interfaces and mSATA support via a full-size mini-PCIe slot. There’s also a half-size mini-PCIe for wireless and dual PCIe-based
GbE ports.

Unlike the earlier Bay Trail based 3.5-inchers, the new model has 2x LVDS interfaces instead of one. There’s also a 4K-ready HDMI 1.4b port, which can run simultaneously with the pair of LVDS connections for triple displays. Other coastline ports include 4x USB 3.0 ports and a COM port. Additional USB and serial interfaces are available along with DIO, Realtek based audio, and a watchdog.
