  • Page 19: 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 the standard EN 62368-1:2014+A11:2017 and must be Safety Extra Low Voltage (SELV) with limited power capability.

  • Page 20: Usb Device Supported

    USB joystick, mouse, or another similar device. If both USBs are connected, diodes D4 and D5 protect the board and use the power from the USB ST-LINK. The board can be powered through this USB USER connector, then LED1 PWR lights and LED2 COM blinks and it can run an application in standalone mode.
