    Would it be possible to know what SMD MOSFET are being used on this board? Schematic is not clear, but Eagle Files shows its a SOT23-3 package MOSFET-NCHANNEL, but would like to know more specifics. Ideally it would be nice to see these also sold in strips of 10 like the SMD PTC or SMD Voltage regulators.

    Yes its possible to charge directly via the FIO. At least for the batteries that SparkFun carries. The “CHG” LED will illuminate while its charging and turn off when its done. One thing to note is that the “ON” LED will only light up when you have a XBee connected and turn on the FIO. ie, it will not light up if you just turn on the FIO by itself.

    Unfortunately it looks like the Sparkfun Eagle Libraries' “SparkFun-Boards.lbr” is for the older version, ie without A4, A5, A6, and A7. So if you want to use those pins, or if you want to use i2c, you need to put in your own off grid headers. It would be nice if Sparkfun can update the library. one entry for the vanilla mini and another for the Pro mini

    You can run it straight from USB power.

    That is correct.

    I am wondering why the Fio was designed with the XBee Socket in the direction the way it currently is. I would have thought having the antenna at the edge of the board will be less likely to get interference and with some Chip antenna XBee socket packages (zigbee, bluetooth, or wifi) their datasheets do state to keep the area under the antenna free of parts or copper (ie. a keep out zone). Was it considered to have the battery and USB connector at the other end of the FIO and turning around the XBee Socket? Or was there a specific reason for the current layout?
