Models / Configs
Data sheets verify two SKU types:
- SBCPRO-X51-01 (PC-61-737): Intel Atom x7211RE, 25V Phoenix power input
- SBCPRO-X51-00 (PC-61-736): Intel Atom x7211RE, 5VSB ATX power, V-by-One support "upon request"
Some retailers may not specify the full model number, so verify power specs and V-by-One requirements before ordering.
Price Range
On Digi-Key, the SBCPRO-X51-00 is listed at $353.80 (qty 1, tax excl). Scaling to $320.50 for quantities of 50. The SBCPRO-X51-01 is listed at €254.27 (tax excl). Note these are B2B prices and subject to change.
Features
The SBCPRO-X51 is essentially a "3.5-inch industrial SBC utilizing Atom x7211RE with a focus on expandability". Modularizing video output via M.2 is rare, allowing for single-cable solutions (Display + Power + Touch) via USB-C.
Major Components (CPU/GPU)
Intel Atom x7211RE (Amston Lake-N): A 2-core/2-thread embedded processor with max 3.2GHz turbo and 6W TDP. Amston Lake Atoms offer up to 125% performance improvement over previous Skylake generation Celerons, providing ample headroom for industrial use despite being entry-level.
Integrated Intel UHD Graphics handles DisplayPort 1.2 (4K@60Hz) and USB-C (DP Alt Mode) (max 3840x2160@60Hz) via the optional M.2 module.
Memory & Storage
DDR5 SO-DIMM x1: Official max 16GB / DDR5-4800. For industrial HMIs, gateways, or light edge AI, 16GB is usually sufficient. Storage: M.2 M Key 2242 x1 for NVMe SSD. No SATA ports or bays, so high-capacity needs require network storage or external solutions.
Expandability covers:
- M.2 2230 for Wi-Fi/BT
- Dedicated M.2 slot for USB-C DP/V-by-One modules
- GPIO, I²C, RS-232/422/485 x2 via headers.
Others (Network / Ports / Power / Software)
Network: Dual 2.5GbE RJ45 offers 2.5x bandwidth of 1GbE, preventing bottlenecks in camera data or log transfers. Ideal for redundant L2 switch configurations.
Rear I/O:
- USB-C (Opt.)
- USB 3.2 Gen1 x2
- DP++ x1
- 3.5mm Audio In/Out
- 2.5GbE x2
- 24V DC-IN
OS: Data sheets confirm Windows 11 IoT Enterprise LTSC 2024 support. Various Linux distros and embedded tools are also supported.
Exterior (I/O, Size, Installation)
The 3.5-inch size (146 x 102 mm) is laid out assuming a heatsink. Though dense, the PCB silk-screening is neat and power lines are organized, typical of quality industrial SBCs.
Top view shows the Atom SoC in the center, surrounded by power circuits and connectors. The SO-DIMM slot is top-side, with Rear I/O (2.5GbE, USB, DP) aligned bottom-right.
Clear view of the compact Rear I/O cluster: 2.5GbE x2, USB 3.2 Gen1 x2, USB-C, DP, and audio. Tall connectors are aligned, with modules sitting behind them, easing enclosure design.
Summary
The SBCPRO-X51 is a "solid 3.5-inch industrial SBC that prioritizes essential industrial needs over flashiness". With 2.5GbE x2, rich Serial/GPIO, and M.2-based video expansion, it strikes a great balance for edge gateways, signage controllers, and embedded systems. It is best suited for projects requiring 24/7 uptime, wide temperature tolerance, and standard software stacks like Windows 11 IoT or Linux.
