BeagleBone Green Eco employs a USB 2.0 Type-C connector that serves dual purposes as both a data communication interface and the primary power input for the board. The USB Type-C port is connected to the USB0 interface of the AM335x SoC.
The USB Type-C port functions as a USB device (peripheral) interface, allowing BeagleBone Green Eco to connect to a host computer for programming, debugging, and serial console access. This connection also provides 5V power to the board.
USB 2.0 data lines DP and DM from the Type-C connector are equipped with common mode chokes for EMI/EMC reduction and ESD protection components to dissipate any transient voltages. The USB_5V power from this connector is routed through the TPS2117DRL power multiplexer IC, which selects between power sources when multiple sources are connected.
