Page 17: Power Supply And Power Selection
5 V and 3 V can also be used as input power supplies, for example when the USB connectors are not connected to the PC. In this case, the STM32F3DISCOVERY board must be powered by a power supply unit or by auxiliary equipment complying with standard EN-60950-1: 2006+A11/2009, and must be safety extra low voltage (SELV) with limited power capability. -
Page 18: Usb Device Supported
The STM32F303VCT6 MCU is also used to drive the second USB mini-B connector (USB USER) which allows the board to be used as a USB Device. The STM32F3DISCOVERY can then act as a USB joystick, mouse, or other similar device. If both USBs are connected, diodes D4 and D5 protect the board and use the power from the USB ST-LINK. -
