2.2.2. SATA Connectors

The two SATA connectors onboard can support up to 3Gbps transfer speeds. Both SATA connectors have
a 7th pin that can provide +5V power to a SATA Disk-on-Module (DOM). When a regular SATA hard
drive is connected, the 7th pin will be a ground pin. The SATA connectors are labeled as "SATA1" and
"SATA2". The pinouts of the SATA connectors are shown below.
