Great performance

ATOM 1 300x212

Utilizing a quad-core Atom processor with unconditionally-efficient heat dissipation, the high performance remains consistent. With up to 32GB of DDR4 memory at a speed of up to 3200MT/s, the processing capabilities are comparable to what’s expected from much larger, more power-consuming, and less affordable computers.



Multiple interfaces

Wide range of capabilities with extended wired and wireless connectivity, Industrial interfaces, and advanced storage and media capabilities.
