** Note that via the serial/UART cable, you may only be getting just enough power to the Raspberry Pi. This is because the USB standard only mandates 500mA. Many devices can supply more than 500mA via their USB port, but this may or may not be the case. Overall 500mA is not enough, particularly if you connect further peripherals to the Raspberry Pi (e.g. USB devices in the Raspberry Pi USB ports, that draw power from the Raspberry Pi). | ** Note that via the serial/UART cable, you may only be getting just enough power to the Raspberry Pi.

By "micro-usb power" we mean power supplied to the Raspberry Pi's micro USB socket, e.g. from a micro-usb power supply (mains powered) or a micro-usb cable.
