  • Page 16: Power Supply And Power Selection

    5V can also be used as input power supplies e.g. when the USB connector is not connected to the PC. In this case, the STM32F4DISCOVERY 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 17: On Board Audio Capability

    • The sound can come independently from different inputs: – ST MEMS microphone (MP45DT02): digital using PDM protocol or analog when using the low pass filter. – USB connector: from external mass storage such as a USB key, USB HDD, and so on.

  • Page 18: Jp1 (Idd)

    Hardware and layout UM1472 JP1 (Idd) Jumper JP1, labeled Idd, allows the consumption of STM32F407VGT6 to be measured by removing the jumper and connecting an ammeter. • Jumper on: STM32F407VGT6 is powered (default). • Jumper off: an ammeter must be connected to measure the STM32F407VGT6 current, (if there is no ammeter, the STM32F407VGT6 is not powered).
