Mini-ITX motherboards have been traditionally used in small-configured computer systems. Originally, Mini-ITX was a niche standard designed for fanless cooling with a low power consumption architecture, which made them useful for home theater PC systems, where fan noise can detract from the cinema experience.

Nano-ITX is a computer motherboard form factor first proposed by VIA Technologies at CeBIT in March 2003, and implemented in late 2005. Nano-ITX boards measure , and are fully integrated, very low power consumption motherboards with many uses, but targeted at smart digital entertainment devices such as DVRs, set-top boxes, media centers, car PCs, and thin devices. Nano-ITX motherboards have slots for SO-DIMM.

In computer design, Pico-ITX is a PC motherboard form factor announced by VIA Technologies in January 2007 and demonstrated later the same year at CeBIT. The formfactor was transferred over to SFF-SIG in 2008. The Pico-ITX form factor specifications call for the board to be , which is half the area of Nano-ITX.

Gumstix was an American multinational corporation headquartered in Redwood City, California. It developed and manufactured small system boards comparable in size to a stick of gum. In 2003, when it was first fully functional, it used ARM architecture system on a chip (SoC) and an operating system based on Linux 2.6 kernel. It had an online tool called Geppetto that allows users to design their own boards. In August 2013 it s

The motherboard size (CPU module) is . There are no computer ports on the CPU module and it is necessary to use an I/O carrier board. The design is intended for medical, transportation and military embedded markets.

It is smaller than other computer-on-module standards such as COM Express, ETX or XTX and is limited to very low power consuming CPUs. The maximum power consumption should be no more than 12 watts.
