US 3.5" SBCs
3.5 Inch Single Board Computers for Compact OEM Systems
The 3.5 inch SBC, at 146 x 102 mm, is one of the most widely used embedded board formats: large enough for a full set of industrial I/O, small enough for a fanless box or a machine enclosure. Available with processors from Intel Atom, Celeron and Pentium through 6th to 13th Gen Intel Core and Core Ultra, and AMD Ryzen Embedded V1000, R1000 and R2000.
Options include triple and quad display outputs, dual or triple Ethernet with 2.5GbE on newer boards, M.2 and Mini PCIe expansion, extended-temperature versions rated from -40 °C and rugged designs with PCIe/104 expansion, suited to automation, medical, transport, defense and self-service systems.
Speak to an embedded board specialist to match the processor, displays and I/O to your system.
