M.2 connector, also known as the Next Generation Form Factor (NGFF) is originally designed for the ultra-thin products. Its compact size could save over 20% of PCB design space compare with mini PCIe connector. M.2 connector applies to high-speed data transmission that supports PCI Express 3.0, SATA 3.0 and USB 3.0.
Miniature in Size:
in which sufficiently save the space of the PCB layout.
There are two key dimension need to check.
- Dim. A：The heights are between min- 2.1mm to max- 8.5mm.
- Dim. B：For double-sided modules, this height is also important to keep in mind.
- SSD Module
- Wi-Fi Module
