USB Interface

The MCBSTM32C board can work as:

  • USB Device: In this mode, usually, a USB A to Micro B cable is used to connect to a PC. The board can be powered through the USB interface.
  • USB Host or USB OTG: In these modes, usually, a Micro A USB cable is used to connect to a USB device or a USB OTG device. A USB host or USB OTG interface must be able to supply the connected USB device. Consequently, the board must be powered through the VIN connector, which must be strong enough to supply the board and the connected USB device. The USB power supply is switched with the IC14 (STMPS2141), which also guards the maximum current consumption.
