Sommaire

What Is an Embedded Computer?

An embedded computer is a dedicated computing platform built to perform specific tasks within a larger system. Unlike a desktop PC designed for general-purpose use, an embedded computer is optimised for a particular application, machine control, data acquisition, protocol conversion, or edge AI inference, and is expected to run continuously, often in harsh environments, for years without intervention.

Embedded Computer vs General-Purpose PC

Feature	Embedded Computer	General-Purpose PC
Form Factor	Compact (SBC, COM, SoM)	Tower, desktop, laptop
Cooling	Fanless passive	Fan-cooled
OS	Linux, Windows IoT, RTOS	Windows, macOS
I/O	COM, GPIO, CAN, LVDS	USB, HDMI, audio
Lifecycle	5 à 10+ years	3 à 5 years
Environment	−40°C to 85°C	0°C to 35°C

Types of Embedded Computers

Single Board Computer (SBC), all components on one board; compact and cost-effective
COM Express / SMARC module, processor module on a carrier board; easy to upgrade
Box PC / Fanless PC, embedded computer in a rugged enclosure, ready to deploy
Panel PC, embedded computer integrated with a touchscreen display

Key Applications

Machine control and automation
IoT and IIoT edge gateways
HMI and operator interface systems
Vision system processing
In-vehicle and transportation computing

Avalue Technology, available through TSL Automation, offers a comprehensive range of embedded computers from compact SBCs to full fanless Box PCs, all with long-term availability commitments for industrial deployments.

An embedded computer is a computing system designed to perform a specific dedicated function within a larger product or system, rather than serving as a general-purpose computing device. In industrial automation, embedded computers run HMI software, collect sensor data, control processes, and enable IoT connectivity, integrated inside machines, control panels, and automated equipment.

Embedded industrial computers are smaller (Mini-ITX, 3.5-inch SBC), fanless for sealed operation, rated for wide temperature ranges (-20°C to +70°C), built with long-lifecycle components, certified for industrial environments (CE, UL, IP ratings), and designed for continuous unattended operation for years. Desktop PCs are designed for 8-hour office use in controlled environments with regular human interaction.

Industrial embedded computers come in: 3.5-inch SBC (single board, for OEM integration), Mini-ITX (170×170mm, for compact system builds), COM Express (processor module plus carrier board), DIN rail PC (35mm DIN clip mount), Box PC (standalone fanless unit), and Panel PC (with integrated display). Each form factor targets different space, I/O, and integration requirements.

Industrial embedded computers typically include: multiple COM ports (RS-232/422/485) for PLC and serial device connections, dual Gigabit LAN for OT/IT network separation, USB 3.0 for peripherals, M.2 for NVMe storage, DisplayPort or HDMI for display output, and optional GPIO, CAN bus, and PCIe expansion. The specific I/O depends on the form factor and product model.
