The motherboard is the main part of a computer which is also termed as ‘Main Board’. It is the base of any computer or in simple words, it is itself a computer. The motherboard is an electronic circuit board that has many different parts like processor installation socket, expansion slots of different types including DIMM slots, PCI, PCIe, and different other types of slots. Different ports are also part of these motherboards for the connectivity of Storage drives and other peripheral devices like printers, scanners. Computer casings are also designed according to their motherboard.
Function of Motherboard
The Motherboard of the computer is a Printed Circuit Board (PCB) which is the center for the connectivity of all components. After getting attached to the motherboard of the computer, all devices become able to transfer data. Any device, input, output, or any other, cannot work or use without attaching with the motherboard. Simply, the motherboard is a central connectivity point for all devices and backbone for their internal communication.
Form Factors of Motherboard
Form factors are different types of motherboard design which are used in different computers. For desktop computers, ATX is the most common form factor which is the advancement of IBM’s AT form factor. This advancement is done by Intel which is then labeled as ATX from AT.
Mainly there are three form factors of computer motherboards which are developed according to different requirements like gaming and others. These three form factors are:
After these main types, their subtypes include Mini and Microarchitecture but ITX is only the form factor that has its Nano version also specially designed for mobiles.
The word ‘ITX’ is the abbreviation of “Information Technology eXtended”. ITX is a small-sized form factor of motherboards. Due to very compact size, these motherboards are also considered as the best option to use in low-cost setups like cars, network devices, and other small computers like these. ITX has 4 different variants according to different sizes. These 4 are:
Mini-ITX motherboard form factor is just like traditional motherboards having memory slots, PCI Express slots, and multiple USB ports along with network port. The power consumption of these motherboards is very low as up to even 5 watts also.
In Nano-ITX legacy, ports are removed and are replaced with mini-PCI and SODIMM while the Pico-ITX motherboard is 75% smaller than Mini-ITX. Pico-ITX motherboard supports all these CPUs that use VIA NanoBGA2 technology. Mobile-ITX motherboards are the smallest form factor that has no ports related to computers. These boards are specially designed for medical equipment, transportation devices, and military used devices.
After knowing all the required information about the motherboards, let’s start reviewing Best Mini ITX motherboards.
