9.12 mSATA Connector - P8 (LCD Module)

The mSATA slot is intended to support SATA based Solid State Drives compatible with the PCI-Express Mini Card slot physical specification but carry SATA signals instead of PCI-E. There is a remote LED indicator at Pin 49 called “Device Activity Signal”. The mSATA card should sink current on Pin 49 to allow the LED to flash to indicate an ACTIVITY.
