New 1/4- and 1/2-size PC/104 boards allow StackableUSB to deliver more compact solutions. A single SAMTEC connector links a motherboard like the Micro/ Sys Pentium III-based SBC1685 with up to eight stacked USB devices. The smaller form factors could allow multiple expansion boards to fit where single PC/104 expansion boards would reside today. This approach allows support for a carrier board that handles multiple expansion modules.
