3.1.1 Input Power Options

The SAM9X60-Curiosity board can be powered through:

  • USB port A (J1)

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 supply topology.

Note: USB-powered operation eliminates additional wires and batteries. It is the preferred mode of operation for any project that requires only a 5V source at up to 500 mA.
