Computer bus interfaces provided through the M.2 connector include PCI Express 3.0 (up to four lanes), Serial ATA 3.0, and USB 3.0 (a single logical port for each of the latter two). The M.2 connector has different keying notches that denote various purposes and capabilities of M.2 hosts and modules, preventing plugging of M.2 modules into feature-incompatible host connectors. Advantech Industrial Motherboards start from the Intel Pentium/Celeron processor N3000 Series to the 6th generation Intel® Core™ processor series with support for the latest I/O interface with faster speeds, wider bandwidth and flexible module device offering such as WiFi RF modules, 3G/LTE RF modules, and SATA modules. There are two types of M.2 key ID to distinguish usage for storage, WiFi, or cellular module. Below are Advantech Industrial Motherboard products covering different types of M.2 key ID:
