Relec Electronics supplies 4″ single board computers from DFI for industrial automation, machine control and embedded computing applications. The compact form factor provides increased processing and expansion capability while supporting integration into space-constrained equipment.

The range includes Intel Atom, Core, Pentium and Celeron processor options, with DDR4 or DDR5 memory capacities up to 64 GB. Storage and expansion options include M.2 NVMe, SATA, microSD and M.2 B-key slots for wireless communication modules. All listed boards support fanless operation, with selected models operating from -30°C to +80°C.

Our engineers can support processor selection, memory and storage configuration, display connectivity, expansion, I/O requirements and thermal design.
