PCI Express M.2 Specification Revision 0.9, Version 3.0

THIS IS A DRAFT SPECIFICATION ONLY AND, AS SUCH, IS SUBJECT TO FURTHER REVISION AND REVIEW WITHOUT NOTICE. THIS DRAFT SPECIFICATION IS PROVIDED TO YOU FOR REVIEW PURPOSES ONLY AND SHOULD NOT BE RELIED UPON FOR DESIGN OR MANUFACTURING PURPOSES.

The M.2 form factor is used for Mobile Add-In cards. The M.2 is a natural transition from the Mini Card and Half-Mini Card to smaller form factor in both size and volume. The M.2 is a family of form factors that will enable expansion, contraction, and higher integration of functions onto a single form factor module solution.

The review period for the PCI Express M.2 Specification Revision 0.9 will end at 5 p.m. (PT) on Monday, October 14, 2013. Any feedback should be sent to administration@pcisig.com.
