ADLINK's COM Express computer-on-module (COM) offerings include the cExpress-SL and Express-SL in PICMG COM.0 Type 6 Compact and Basic Size form factors, respectively. Both Basic and Compact size modules are available with 6th generation Intel® Core™ i7, i5 or i3 processors and accompanying Intel® QM170 and HM170 Chipset. ECC memory is supported by models utilizing the Intel® Xeon® processor E3-15XX v5 family and Intel® CM236 chipset. DDR4 memory is supported up to a total of 32GB, with a lower voltage compared to DDR3 resulting in a reduction in overall power consumption and heat dissipation. These new COMs also provide support for three independent UHD/4K displays and are well-suited for applications in automation, medical, and infotainment, with extended operating temperature range optionally available for transportation and defense applications.

The ADLINK cExpress-SL computer-on-module with built-in SEMA Cloud functionality is ready-made for Internet of Things (IoT) applications. The cExpress-SL is able to connect legacy industrial devices and other IoT systems to the cloud, extract raw data from these devices, determine which data to save locally and which to send to the cloud for further analysis. The results these analyses can provide valuable information for policy decision making and generate innovative business opportunities.
