Stackable Unified Module Interconnect Technology (SUMIT) is a connector between expansion buses independent of motherboard form factor. Boards featuring SUMIT connectors are usually used in "stacks" where one board sits on top of another. It was published by the Small Form Factor Special Interest Group. Details Two identical connectors carry the signals specified by the standard. Commonly referred to as SUMIT A & SUMIT B, designers have the option of designing with either both SUMIT A and B, or just SUMIT A. The signals carried within each connector is as follows: ''SUMIT A:'' * One PCI-Express x1 lane * Four USB 2.0 * ExpressCard * LPC * SPI/uWire * SMBus/I2C Bus ''SUMIT B:'' * One PCI-Express x1 lane * One PCI-Express x4 or four more PCI-Express x1 lanes As of August 2009, three board form factors used the SUMIT connectors for embedded applications: ISM or SUMIT-ISM 0mm × 96mm Pico-ITXe 2mm × 100mm and Pico-I/O 0mm × 72mm See also * VMEbus * VPX * CompactPCI * PC/104 ...

Small Form Factor Special Interest Group
The Small Form Factor Special Interest Group (SFF-SIG, pronounced ''ess-eff-eff-sig'') is an international non-profit standards body focused on modular computer hardware technologies used in embedded and small form factor computers and controllers. Members are mainly computer board and component manufacturers. The group was founded in 2007 and had a web site until early 2020. History SFF-SIG generally targets low power components and processors from VIA Technologies and Intel including the Nano and Atom processors, although products for RISC processors were discussed in some working groups. VIA, WinSystems, and Octagon Systems were founding members of SFF-SIG. It was created in 2007. A logo and web site debuted in April 2008. SFF-SIG creates, promotes, and maintains embedded computer standards for form factors and computer buses. Examples include the governing documents and trademarks for CoreExpress, Pico-ITX, Express104, and SUMIT. Members use the specifications to build s ...
