Advantech MIO-5355 3.5-inch SBC features Qualcomm QCS6490 or QCS5430 SoC for industrial edge AI

Advantech MIO-5355 is a 3.5-inch SBC based on Qualcomm QCS6490 or QCS5430 Edge AI processor. The board features up to 8GB of LPDDR5 memory, 128GB of UFS storage, and supports various operating systems, including Windows 11 IoT Enterprise, Ubuntu 24.04 LTS, and Yocto Linux.

We have seen other QCS6490-based hardware in the past, such as the Radxa Dragon Q6A, the Quectel QSM560DR SBC, or the Rubik Pi 3, most of which come in compact form factors. The Advantech MIO-5355 takes a different approach, using a standard industrial 3.5-inch form factor (146 × 102 mm) and targeting industrial deployments with support for –20°C to 70°C operation and long-term availability.

The block diagram confirms that the QCS6490/5430 sits on an OSM Size-L module (AOM-2721) soldered onto the 3.5-inch SBC board, rather than being directly soldered onto the main PCB. This is a common practice in industrial design to simplify manufacturing variations between SKUs.

On the software side, Advantech offers Windows 11 IoT Enterprise LTSC, Ubuntu 24.04 LTS, and a Yocto 4.0 (Kirkstone) BSP. The company also provides its “SUSI” API for hardware monitoring, brightness control, and GPIO management. More information, including downloads and an installation guide, is available in the user guide.

At the time of writing, the company only mentions two SKUs, MIO-535506Z-U7A1U (Taiwan origin) and MIO-535506Z-U7A1 (China origin), both of which are based on the QCS6490, and there are no SKUs for the QCS5430.

The Advantech MIO-5355 is already available, but like most industrial hardware, pricing has not been made public. You can find more details and request a quote on the product page. Avnet has also just announced availability, and the product is listed on other resellers such as Fortec US and APC Technology (UK).
