LS-576 - 5.25" EBC 3rd Gen Intel Core i7/i5/i3 Mobile QM77

Product image


The LS-576 is a 5.25" mini-board designed for the 3rd and 2nd generation Intel Core i7/i5/i3 processors in the rPGA988B socket. The 5.25" SBC is based on the Intel QM77 Express chipset which is part of the mobile Intel 7 Series Chipset family. When used with an Intel 3rd generation 22 nm Core i7/i5/i3 which have the HD Graphics 4000 that contains a refresh of the seventh generation graphics core, DX11 gives smoother rendering at higher resolutions for an improved 3D experience and OGL4.X  gives improved realism for OGL 3D. With lower power consumption, this innovative two-chip solution provides Intel Intel Hyper-Threading technology giving you smart multitasking performance to move between applications quickly. 

The LS-576 supports 16GB DDR3 SO-DIMM memory, comes with DVI, VGA & LVDS, 6 x Giga LAN, 4 SATA2 & 2 SATA3, HD Audio, 5 x RS232 & 1 x RS232/422/485, 4 x USB2.0,4 x USB3.0,  GPIO and two PCIE mini card expansion socket.
