The input power pin to the Flame. Additionally when
operating via a Universal Serial Bus (USB) this is the USB
power connection (+5V) which can be used to power other
peripherals (Care must be taken to insure that the peripheral
complies with USB Specifications). The entire assembly
should not draw more than 500 mA.
NOTE: Do not connect both USB power and Auxiliary power
(as an input) at the same time.
*See the Caution below.
Caution
Do not connect the GPIO pins to 5V. The GPIOs are not 5V tolerant and will be
damaged if connected to 5V. The maximum voltage is 4V for the 3.3V logic pins
and 3V for the 2.5V logic pins.
