Micro/sys released its StackableUSB CPU board on a Pentium III processor, creating an SBC that provides I/O expansion via StackableUSB peripherals. In addition to all standard PC features, the SBC1685 includes a Gigabit Ethernet port, four USB 2.0 high-speed (480 Mbit/s) ports, four USB 1.1 full speed ports, and a CompactFlash interface. With up to 256MB of socketed SDRAM, and full PC-compatibility, high performance embedded control systems can be implemented on this PC/104 size SBC. The Intel 815E chipset enables the SBC1685 to operate systems and applications that require full disk-based GUI systems. The CPU board can boot Linux, Windows CE, Windows XP, VxWorks, DOS, Phar Lap ETS, and other PC-compatible operating systems.
