Daughter boards for Beagleboard XM

Hi All,

  I am looking for a suitable daughter board to fit the Beagleboard XM,
that will provide voltage level shifting for the I2C port and other
GPIOs. I have seen the Trainer-xm board from Tincan which also
includes ATmega328 process which I don’t need.

  Can anyone suggest another suitable daughter board and where it can
be purchased?

    Thanks Ernie

If you only need level translations, it is very easy to build what you
need yourself. In ourhobby projec[1,2] t we are using TI's TXS0108E
voltage-level translator [3] with SSOP to DIP adapter [4]. Works just
fine for I2C and GPIO.

Andrey,

  Thanks for your reply.
  Initially my plans were to use a SSOP to DIP converter and I have
bought some, but found the device very small and difficult to solder.
         Do you have any good suggestions to make it easier?

  Out of interest where to you power the 2 sides of the convert from?

      Thanks again for information.

there is sn74lvc8t245 in soic package (1.27mm), should be slightly
easy to solder

thanks, Alex

This one is what we were using in the past:

From expansion slot. Will write later more precise answer (do not have
the board right now and do not remember it out of my had).
