4.8.4 SATA/SATADOM
The conga-TEVAL3/COMe 3.1 provides four standard SATA 6 Gbps connectors (X20 - X23). SATADOM devices are supported on all connectors
while external power is connected. Use jumper JP1 to provide +5V power on pin 7 of connector X20. The 5V power rail on SATA0 pin 7
(SATADOM mode) is protected by a 0.5A fuse.
The SATA activity LED (D9) lights when an activity occurs on any of the SATA interfaces. The pin header X26 provides an option to connect
external SATA activity LED (serial resistor 220R to 3.3V is implemented on the board).
