We have different scenarios for motherboard applications, generally have different requirements and specifications for the size of the motherboard, common embedded motherboards can be divided into ATX, M-ATX, ITX, Thin-ITX, some for special application scenarios, as well as the PICO-ITX, 3.5-inch, Special Gauge, SDM, etc., the following are some of the introductions:
1, ATX ( Advanced?Technology?Extended) motherboards:
ATX is a motherboard specification developed by Intel in 1995, and is the first major change in computer chassis and motherboard design in many years.ATX motherboards can be interpreted as full-size motherboards, and are the most common type of motherboards, which are usually larger, support multiple expansion slots, and offer abundant rear ports, the distinguishing feature is that the memory is mostly 4 slots, and the slots underneath are usually 7 expansion slots, but take up 8 expansion slot positions (nowadays, it is also usually 4 PCI-E full-length slots + 2 PCI-E?1× slots, or m.2 slots). Applied to consumer desktop motherboards, large board design, good expandability.
2, Micro-ATX motherboards:
Micro-ATX motherboards are a bit smaller than ATX motherboards, which is a scaled-down version of ATX, and usually have fewer expansion slots and interfaces. Memory is also typically 4 slots, and expansion PCI-E slots are typically only 4 slots occupying 5 spaces. This is the most common size version of the common specification, and their width does not change. 244mm is commonly used in consumer desktop motherboards, and the price is better than an ATX motherboard.
3, ITX?motherboard:
It is designed specifically for small computers motherboard specifications, size 170mm × 170mm?, including a full-size PCI-E?slot, you can install a discrete graphics card, because the size of the motherboard becomes smaller chassis also becomes smaller, because of its small size and get many users like, by a variety of manufacturers are widely used in a variety of commercial and
Intel? Rapid Start Technology
2nd Generation Intel? Core? Processors offer an outstanding Blu-Ray Stereo 3D experience in a compact form factor.
4, Thin-ITX?motherboard:
In fact, its size is the same as ITX?but the difference is in the I/O?interface part, hardened height limit, not allowed to exceed 25mm, which is in order to plug into a smaller chassis, in addition to the Thin-ITX?basically the use of laptop memory, the cancellation of the PCI-E slot motherboard products. Expandability is poor, applied to small chassis products, such as mini computers, all-in-one computers.
5, Pico-ITX motherboards:
The Pico-ITX specification was first released by ICMG in 2007. Pico-ITX motherboards are 100×72mm in size, and are used for special embedded products, such as drones, robots, smart homes, in-vehicle devices, and medical instruments and devices.
6, 3.5-inch ARM motherboard:
The size of the motherboard is 146mm?x102mm, which should mainly be used for standard embedded motherboards in the commercial display market, and is mainly used in floor-standing and wall-mounted All-in-One PCs, touch control All-in-One PCs, advertisement machines, digital signage and other products.
