3.5-inch Industrial SBC "SBCPRO-X51" Review: USB-C One-Cable and V-by-One via M.2 Expansion

FORTEC Integrated announced the 3.5-inch SBC "SBCPRO-X51" with Intel Atom x7211RE (Amston Lake). It supports adding USB-C one-cable output or V-by-One via M.2 expansion modules. With dual 2.5GbE and wide temp support, it hits the spot for HMI, signage, and edge gateways.

On November 25, 2025, FORTEC Integrated (FORTEC Group) announced the SBCPRO-X51, a 3.5-inch SBC powered by the Intel Atom x7211RE (Amston Lake). Product info is available on the official page and press section.

Its feature is the ability to retroactively add interfaces like "USB-C single cable (Video + Power + Touch)" or "V-by-One" via M.2 expansion modules. The concept of "tailoring I/F per application" stands out in the industrial SBC market.

Conversely, points like the 16GB memory cap or unclear storage usage protocols in primary info need clarifying before purchase. Whether you can accept it as an "inquiry-based industrial product" is the key decision factor.

Intel Atom x7211RE (TDP 6W) + DDR5-4800 + M.2 Expansion Module packed into a 146x102mm 3.5-inch industrial SBC. Configured for HMI, signage, and gateway use with dual 2.5GbE and wide temp support (-20 to +80°C).

Features

SoC / CPU

The core is Intel Atom x7211RE. A dual-core up to 3.20GHz, 6W TDP embedded CPU. For industrial SBCs, "Thermals/Power/Availability/Long-term use" often beat peak performance. This design fits well with 24/7 operation and the -20 to +80°C range. However, don't expect to run heavy local GenAI. No dedicated NPU is verified in primary info. While optimization via OpenVINO on CPU is possible, it's safer to view it as "light inference tasks only".

Memory & Storage

DDR5-4800 SO-DIMM x1, Max 16GB. Clean cut for an SBC; sufficient for light-mid edge processing, HMI, or gateways. But the cap is concerning for virtualization or heavy DBs. Storage is one M.2 M Key 2242 (Storage). Protocols (NVMe vs SATA) aren't explicitly clear in primary info, so checking the latest datasheet or asking during quoting is recommended.

M.2 Expansion Module (USB-C / V-by-One)

The key feature. Adding "USB-C Single Cable (Video+Power+Touch)" or "V-by-One" via M.2 module is intriguing. The USB-C module lists PD 60W and USB 2.0 for touch, simplifying wiring and chassis design. Hits the spot for HMI/signage requirements to "minimize wiring".

Network & Other I/O

2.5GbE x2. Approx 2.5x bandwidth of 1GbE, reducing bottlenecks for multi-camera streams or log transfers. Dual LANs suit gateway use (separating "Field NW" and "Upper NW"). Rear I/O: USB 3.2 Gen1 x1, USB 2.0 x2, DP++, 2.5GbE x2, Audio In/Out. Internal: RS-232/422/485, GPIO, TPM 2.0, Watchdog. Solid industrial toolset.

Assumes operation with a heatsink. Seeing a straightforward thermal design is reassuring.

Summary

SBCPRO-X51 is for those who want not just "Small and Rugged" but also "Less field wiring, easier chassis design". The ability to add quirks like USB-C one-cable or V-by-One via M.2 gives it character. Best for: 24/7 uptime, wide temp range, standard soft stack (Windows 11 IoT/Linux). HMI, Digital Signage, Edge Gateways. Price starts mid-200 Euros (DigiKey), reasonable for industrial gear.
