A Computer-on-module (COM) is a type of single-board computer (SBC), centered on a single microprocessor with RAM, input/output controllers and all other features needed to be a functional computer on the one board. However, unlike a single-board computer, the COM module will usually lack the standard connectors for any input/output peripherals to be attached directly to the board. Instead, the wiring for these peripherals are bussed out to connectors on the board. The module will usually need to be mounted on a carrier board which breaks the bus out to standard peripheral connectors. A COM solution offers a dense package computer system for use in small or specialized applications requiring low power consumption or small physical size as is needed in embedded systems.
