If you want to make your projects truly wireless, you can power the device with a single
cell LiPo/Lithium Ion (3.7V). The Xenon has an on board LiPo charger that will charge and
power the device when USB source is plugged in, or power the device from the LiPo alone
in the absence of the USB.
NOTE: Please pay attention to the polarity of the LiPo connector. Not all LiPo
batteries follow the same polarity convention!
This pin is internally connected to the positive terminal of the LiPo connector. You can
connect a single cell LiPo/Lithium Ion or a DC supply source to this pin for powering the
Xenon. Remember that the input voltage range on this pin is 3.6 to 4.2 VDC.
This pin is the output of the on board 3.3V step-down switching regulator (Torex
XC9258A). The regulator is rated at 1000mA max. When using this pin to power other
devices or peripherals remember to budget in the current requirement of the Xenon first.
This pin can also be used to power the Xenon in absence of the USB or LiPo power. When
