1, ATX (advanced technology extension) motherboard:
ATX is the motherboard specification made by Intel Company in 1995, which is the first major change in computer chassis and motherboard design for many years. ATX motherboard can be understood as full-size motherboard, which is the most common motherboard type. It is usually large, supports multiple expansion slots, and provides a rich rear interface. The notable feature is that the memory is mostly 4 slots, and the lower slot is usually 7 expansion slots, but it occupies 8 expansion slots (now it is generally 4 PCI-E full-length slots +2 PCI-E 1× slots, or m.2 slots). Used for consumer desktop motherboard, large board design, good scalability.
2. Micro ATX motherboard:
Miniature ATX motherboard is smaller than ATX motherboard, which is a smaller version of ATX and usually has fewer expansion slots and interfaces. Generally, there are 4 slots in the memory, and only 4 slots in the expansion PCI-E slot occupy 5 spaces. Among the common specifications, the size versions are the most, and their widths will not change, all of which are 244 mm They are commonly used in consumer desktop motherboards, and their prices are better than ATX motherboards.
3.ITX motherboard:
It is a motherboard specification specially designed for small computers, with the size of 170mm× 170mm, including a full-size PCI-E slot, which can be used to install independent graphics cards. Because the motherboard is smaller, the chassis is smaller, and it is liked by many users because of its small size. It is widely used in various commercial and industrial applications by various manufacturers, and often used in embedded small chassis products.
4. Thin ITX motherboard:
In fact, its size is the same as ITX, but the difference lies in the I/O interface, which rigidly stipulates the height limit and does not allow it to exceed 25mm, so as to fit into a smaller chassis. In addition, Thin-ITX is basically a motherboard product that uses notebook memory and cancels PCI-E slot, which has poor scalability and is suitable for small chassis products, such as mini computers and all-in-one machines.
5. Micro ITX motherboard:
Pico -ITX specification was first published by ICMG in 2007. Pico ITX motherboard size is 100×72mm, which is used for special embedded products, such as drones, robots, smart homes, vehicle-mounted equipment, medical instruments and equipment, etc.
6.3.5 inch ARM motherboard:
The size of the motherboard is 146mm x 102mm, which is mainly used as the standard embedded motherboard in the commercial display market, and is mainly used in floor-mounted and wall-mounted integrated machines, touch integrated machines, advertising machines, digital signs and other products.
