Taiwan Commate Computer Inc.(COMMELL), the worldwide leader of Industrial single board computer, is releasing the 3.5" SBC - LS-377 that designed for the new Intel® mobile Core i7/i5/i3 processors in the rPGA988A socket. The LS-377 based on Intel® QM57 chipset, along with a compatible processor that is Intel® next generation 64-bit, dual-core processors built on 32 nm Core i7/i5/i3 with HD Graphic function, placing the memory controller and graphics core on the processor die provides a two-chip system architecture,  Innovative two-chip solution provides Intel® Turbo boost technology and Intel Hyper-Threading technology which maximizes performance to match your workload and lower power than previous three-chip platform. This platform is ideal for developing high-performance systems for industrial control and automation, retail, gaming, print imaging and digital signage.

COMMELL's  3.5" SBC is provided for up to 4.0 GB of DDR3 800/1066 MHz data transfer rate dual-channel system memory, 1-GB and 2-GB DDR3 DRAM technologies are supported for x8 and x16 devices. When along with Intel 32nm Core i7/i5/i3 processor that provided Intel® HD graphic function with Dynamic Video memory Technology, MPG2 / WMV9 / VC1 / AVC hardware acceleration, advanced pixel adaptive De-Interlacing and High quality Scaling, additional display features include 24-bit dual channel LVDS and DVI interface.

The LS-377 comes with PS/2 Keyboard and Mouse, 1 x RS232 & 1 x RS232/422/485, Networking is provided by Intel® 82574L Giga LAN, 6 x USB2.0 ports, It offers support for Intel® High Definition Audio enables increased bandwidth for high quality audio. Also support for eSATA enables the full SATA interface speed up to 3GB/s, support for RAID 0 / 1 enables high reliability for personal data, or maximum storage performance for intensive applications.  Mini-PCI and Mini-PCIe sockets easily using any other add-on cards.
