    On the very first page is an information box about a Rev. 2 board. There's a typo. It reads
    XBee doc ch 2 said...
    This section pertains to the XBee 5V/3,3V Adapter Board Rev A. A Rev B board is in development, that will have I/) buffering and LED configurations
    That should, of course, say "I/O buffering".

    A later information box reads

    CAUTION!
    VCC may be used as a 3.3V supply output, but the FAN2500S33X regulator used on the adapter is only rated at 100mA continuous, 300mA peak current..
    It would be helpful here to point out that the transmit current of the "Pro" XBee is over 200 mA, and therefore that this board should not be used in an application in which an XBee Pro transmits constantly or nearly constantly. The beginner may not know why he or she is being warned about the regulator output.

    On page 22, in the list of pin connections, the "I" in "RSSI" seems to be underlined, and not in bold.

    On page 23:

    Beware of Dueling Power Supplies!
    Take care with all boards that two sources of powers are not applied, such as connecting both 5V AND 3.3V

    supplies. Damaging current will flow between the two sources.

    How about "that two sources of power [noparse][[/noparse]not "powers"] are not applied at the same time...". This comes up again later in the chapter as well.

    On page 25 is

    Red: USB Transmit

    Green: USB Receiver

    I believe the second should be "Receive", not "Receiver".
