3.5-inch Whiskey Lake SBC ships with Ubuntu image

Apr 30, 2020 — by Eric Brown 8,260 views

Advantech’s 3.5-inch “MIO-5373” SBC runs Ubuntu or Win 10 on an 8th Gen Whiskey Lake CPU and offers up to 32GB DDR4, up to 64GB eMMC, triple display support, 2x GbE, 4x USB 3.0, 2x M.2, and MI/O expansion.

The MIO-5373 follows a long list of other 3.5-inch SBCs with Intel’s 8th Gen Whiskey Lake processors (see farther below). It may be late to the party, but the SBC is one of the more feature-rich models we have seen.

Although it lacks USB 3.1 Gen2, you get all the usual features plus triple and 4K displays, eMMC, CAN, ruggedization features, M.2 with NVMe, and Advantech’s MI/O expansion interface. The SBC is designed for high-powered, but space-constrained embedded applications such as medical equipment, automation control systems, outdoor kiosks, CNC machines, and factory automation add-ons for AGVs (Automated Guided Vehicles).

Advantech supports the MIO-5373 with Win 10 and Ubuntu Linux images accompanied by drivers and software APIs for the built-in iManager3.0, a hardware/software platform based on Advantech’s EIO-201 embedded controller. The controller offers power sequence control, GPIO, hardware monitoring, smart fan control, and a watchdog timer. It also has domain-focused features like RS-232/422/485 at up to 1Mbps, I2C (100kb/400kb/1Mb), and CANBus.

The SBC supports Advantech’s optional WISE-PaaS/DeviceOn IoT device operations and management software, which monitors device health, provides real-time control over power on/off, and performs troubleshooting routines and OTA updates. The platform “makes it easy to integrate, visualize, operate, and manage industrial IoT devices through public or private cloud,” says Advantech.


The MIO-5373 can be purchased with 15W Whiskey Lake CPUs including the dual-core Core i3-8145UE and four quad-core options led by the up to 4.4GHz Core i7-8665UE. A Celeron 4305UE is available on request.

Only the quad-core i7-8665UE and i5-8365UE SKUs support -40 to 85°C temperatures while the others have a 0 to 60°C range. The SBC cools the CPU with four symmetrical heatsink screw holes and is protected with 95% relative humidity, non-condensing humidity resistance and 3.5Grms vibration resistance. The board runs on a wide-range 12-24V AT/ATX power supply with optional DC jack.
