The M.2 Specification Revision 5.0, Version 1.0 (often abbreviated as M.2 r5.0 v1.0) is a critical update that aligns the M.2 form factor with the PCIe 5.0 base specification. Released by PCI-SIG, this document formally defines how M.2 connectors, card layouts, and system integration must evolve to support 32 GT/s signaling – a doubling of the data rate from PCIe 4.0 (16 GT/s).

The PCI Express M.2 form factor and connector standard continues to evolve alongside PCIe protocol revisions. Revision 5.0 (version 1.0) of the M.2 specification documents the mechanical, electrical, and connector-pin mappings needed to support PCIe Gen5 signaling and related interfaces in M.2 modules and host connectors.
The above changes drive almost every other update in the document.
M.2 Rev 5.0 also defines a new Compliance Board (CLB-M.2) with industry-standard SMPM connectors for oscilloscope-based TX/RX testing – replacing older probes that were ineffective at 32 GT/s.
