Axiomtek CEM521 Intel Core & Intel Celeron COM Express Type 6 Compact Module


The Axiomtek CEM521 is powered by the latest 8th generation Intel Core i7/i5/i3 processor or Intel Celeron processor 4305UE (codename: Whiskey Lake-U). It is suitable for harsh operating conditions with an extended operating temperature range of -40°C to +85°C (-40°F to +185°F). The 4K-ready system on module was designed for graphics-intensive Industrial IoT applications including industrial control system, medical imaging, digital signage, gaming machines, military, and networking. The palm-sized CEM521 is packed with a variety of rich features including low power consumption, industrial temperature support and high graphic processing capability. The COM Express Type 6 compact module supports two DDR4-2400 SO-DIMM sockets for up to 64GB of system memory. The power-efficient CEM521 is also integrated with Intel® Gen 9 graphics and supported with DX12.0, OCL 2.0 and OGL 4.3 for excellent graphics performance with a resolution of up to 4K (4096 x 2160 @ 30 Hz). It offers three independent display support through one LVDS, one VGA and one DDI ports for HDMI/DisplayPort.
