Digi does sell SMT versions of the XBIB board - if your SMT module is not soldered down.
Are you designing your own hardware?
I have designed a few XBee carriers, which all use some form of ‘selector’ (like 74x157 or 251) so that the RX/TX pins can be accessed via an FTDI ‘USB to 3.3v’ cable, which allows running XCTU against the XBee while in place on the board.
