Small Form Factor Special Interest Group

The Small Form Factor Special Interest Group or 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.

Operations

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 specialized embedded computers used in both commercial and rugged environments where applications insist on reliable control and data acquisition, for example.

Primarily focused on hardware, SFF-SIG defines new single-board computer (SBC) and computer-on-module (COM) form factors. SFF-SIG standardizes expansion connectors for the latest desktop and notebook chipset interfaces to create the building blocks required by system manufacturers to rapidly deploy their unique applications. Each specification is a free open standard by ITU-T definition.
