You have a lot of power supply options here! We bring out the '''BAT''' pin, which is tied to the lipoly JST connector, as well as '''USB''' which is the +5V from USB if connected. We also have the '''3V''' pin which has the output from the 3.3V regulator. We use a 500mA peak regulator. While you can get 500mA from it, you can't do it continuously from 5V as it will overheat the regulator. It's fine for, say, powering an ESP8266 WiFi chip or XBee radio though, since the current draw is 'spikey' & sporadic.
