Sommaire

The 3.5-Inch Form Factor: Small but Capable

The 3.5-inch SBC form factor (146 × 102 mm) is a long-established standard for embedded computing, small enough to integrate into tight enclosures and custom systems, while offering full PC architecture with standard OS support. Avalue's 3.5-inch SBC range brings modern Intel processor options to this proven form factor.

IoT Gateway Applications

The most common use case for a 3.5-inch SBC in industrial settings is an IoT gateway, a device that:

Collects data from PLCs, sensors, and field devices via Modbus, OPC UA, or Profinet
Pre-processes and filters data locally
Publishes data to MQTT brokers, cloud platforms, or MES systems over Ethernet or 4G
Runs Node-RED, Python scripts, or SCADA edge agents

Key Specifications

Processor, Intel Atom or Celeron N-series (6 à 10W TDP, fanless capable)
Memory, up to 16GB DDR4
Storage, M.2 NVMe + SATA, eMMC option
I/O, 2× COM (RS-232/422/485), 2× LAN, 4× USB, Mini-PCIe for WiFi/4G modules
OS support, Windows 10 IoT, Linux Ubuntu/Debian

Questions fréquentes

A 3.5-inch SBC (146×102mm) is most commonly used as an industrial IoT gateway, collecting data from PLCs, sensors, and field devices via Modbus, OPC UA, or PROFINET, pre-processing it locally, and publishing to cloud platforms or MES systems. Its small form factor fits inside machine enclosures and control cabinets where full-size industrial PCs cannot be accommodated.

A 3.5-inch SBC is a compact single-board computer optimised for embedded integration with lower power consumption (typically 6 à 25W TDP), fewer expansion slots, and a smaller footprint. A full industrial PC offers more I/O, larger storage capacity, higher performance, and easier software deployment. SBCs are ideal for dedicated gateway and edge processing tasks; full PCs suit SCADA workstations and multi-application platforms.

Avalue 3.5-inch SBCs support Windows 10 IoT Enterprise LTSC, Windows 11 IoT Enterprise LTSC, and Linux (Ubuntu, Debian, Yocto). The choice depends on your application, Windows is preferred for compatibility with industrial software tools; Linux is preferred for custom IoT gateway applications, containerised deployments, and MQTT/OPC UA middleware.

Yes, Avalue 3.5-inch SBCs with Intel Celeron or Core i-series processors can simultaneously poll multiple PLCs via Modbus TCP/RTU, EtherNet/IP, or OPC UA, log data to local SSD, and publish to cloud platforms. For applications requiring simultaneous polling of 10+ PLCs at high rates, choose an SBC with an i5 or i7 processor and dedicated NIC for OT network isolation.
