 == Getting Started
+
+The GW7905 can be powered using the J13 (2-pin) connector (supports 3.6 to 20V DC input) or through the J14 USB Type-C connector using a USB-C charger. The USB-C power profile supports the following profiles by default:
+
+ - PDO1 (low priority) 5V@1.5A
+ - PDO2 (medium) 15V@1.5A
+ - PDO3 (high priority) 20V@1.0A
+
+Other profiles can be programmed into the controller as well. Contact support for other options. 
+
+Depending on the type of cards loaded in the Mini-PCIe sites PD02 or PD03 profiles might be required. The board typically runs at 2.5W without any Mini-PCIe cards installed.
