Introduction:
MM3U is vertical extender from MiniCard slot to MiniCard together with DB3U.It is very convenient especially to apply“full-size”MiniCard module to “half-size”MiniCard slot.
As MM3U has a SIM card slot, wireless MiniCard modules which require SIM Card such as 3.5G HSPA can be used, even though original MiniCard slot is not connected to SIM card slot.
As all of 1.5V power supply pins of MiniCard slot have series termination, 1.5V power supply can be isolated separately so that MiniCardmodules using 1.5V pins as GPIO can be used.
Combination of MM3U and DB3U is the best solution for MiniCard evaluation.

Notice:
MM3U-DB3U with mPCIe module works only in mPCIe slot of system. mSATA module only for mSATA slot as well.
Do NOT insert mPCIe module into mSATA slot, or mSATA module into mPCIe slot via MM3U-DB3U. Otherwise, permanent damage may occur for the module, the MM3U-DB3U and/or the system.
