Components
The Teledyne LeCroy Gen3 M.2 Interposer kit has the following components:
• M.2 Interposer with Carrier board
• Connector cable assembly 18 inches for connection to host slot
• Power supply
• Extension bracket kit (three metal brackets and six screws)
• Stand off screw and nut
The M.2 technology specification includes two connector definitions: Socket 2 and Socket 3. Socket 2
keyed as “B” allows for PCIe x2 interface for SSDs, WWAN or other non-storage devices. Socket 3
keyed as “M” is strictly for high-performance storage, offering x4 lanes of bandwidth in this form factor.
In some cases a “B/M” keyed SSD will also be available and it is both a Socket 2 and 3 type. A “B”, “M”
or a “B/M” keyed memory SSD can then be connected to a host based B or M connector which is
capable of supporting any of the devices mentioned above.
Teledyne LeCroy provides two configurations of the M.2 Interposer to support these three types of
devices. One interposer is for use with B and B-M type memory modules and a second interposer is for
use with M and B-M type M.2 memory modules. Both interposers support the common 42mm, 60mm,
80mm, and 110mm SSD lengths.
