5.25" ESB and EBX

203(W) x146(L) mm; 8"(W) x 5.7"(L)

EBX is a de-facto standard of industry set by Motorola/Ampro and some other industrial PC makers. Lots of IPC makers follow this standard to design their proprietary layout as a 5.25" embedded system board.

microATX motherboards

243(W) x 243(L) mm; 9.6"(W) x 9.6"(L)

ATX is a well-known form factor for consumer motherboards. It has various versions like microATX, FlexATX and EmbATX for different market segments and vertical applications...View more microATX

Half-sized ISA SBC(Single Board Computer)

185(L) x 121.5(W) mm; 7.3"(L) x 4.8"(W)

This is a standard form factor, featuring ISA add-on cards, that is widely adopted in industrial applications during the last decade.

PC/104 & PC/104-plus

Following the industrial standard set by PC/104 consortium, PC/104 and PC/104-plus are defined as a mini PC module with ISA extension (PC/104) and with PCI extension (PC/104-plus) functionality individually.
