The USB port is the easiest way to power up the Argon. Please make sure that the USB
port is able to provided at least 500mA. Power from the USB is regulated down to 3.3V by
the on board Torex XC9258A step-down regulator.
The pin is internally connected to the VBUS of the USB port. The nominal output should
be around 4.5 to 5 VDC when the device is plugged into the USB port and 0 when not
connected to a USB source. You can use this pin to power peripherals that operate at such
voltages. Do not exceed the current rating of the USB port, which is nominally rated to
500mA. This pin is also protected with an internal fuse rated at 1000mA.
