3.1.1.2 USB Type Micro-B Connection (J2)

The SAM9X75-Curiosity board can be supplied by an external USB Micro-B cable with the following absolute maximum ratings:

  • VIN max: 5.75V
  • IIN max: 500 mA in USB 2.0
  • USB connector: USB Type Micro-B

The USB-powered operation comes from the USB device port connected to a PC or a 5 VDC supply.

The USB supply is enough to power the board in most applications. It is important to note that when the USB supply is used, the USB port has limited power.

The following figure shows the input power USB supply.
