Equipped with the efficient Intel Celeron N3350 processor and 4GB of dual channel LPDDR4 memory, the AWS-CL210G-10 brings stable operation with Intel Platform Trust Technology (PTT).

This industrial fanless gateway brings the ease of x86 architecture to the Ultra Small Form Factor with dual LAN and dual Mini Display Ports. Storage temperature range: -20°C to 70°C.

The industrial-grade Hardshell Fanless Technology found on the AWS-CL210G-10 not only looks good, but also protects the system from dust, debris, chemical, and moisture ingress. Its unique cast aluminum chassis efficiently dissipates heat while allowing for space-saving mounting with a DIN rail mounting kit included.

An mSATA slot (shared with the full-height mPCIe) or microSD card slot on the back can accommodate additional storage if more than the 32 GB of eMMC storage is needed."
