You can power it by supplying power to the VBat pin, though this will bypass the fet and self-resetting fuse, and unless it's being supplied with 5v or more, don't plug USB into it (see http://www.espruino.com/EspruinoBoard power section). It's probably better to pipe in external power through the battery connector for this reason.
You can get power off of the VBat pins (at whatever voltage is supplied, 4.7 if powered at 5v over USB, due to drop across the diode), or the 3.3 pin (at 3.3 volts, ofc).
If you're powering it off of 5v, you can get 5v from the VBat pins (the 4.7 when on USB is enough to run stuff expecting 5, in almost all cases). Otherwise, there's no source of 5v on the board - it's only got the one regulator to provide 3.3v to run the chip.
