    Hi Christopher,
    I looking for a development kit for the AT86RF231
    and recently I found a nice picture in Your Picassa gallery
    Could You sell me two pieces of them ?

      That was just an experimental board, I’m not selling them (and can’t do so with my EAGLE license). The board can be produced by Seeed Studio (http://www.seeedstudio.com/) and the parts soldered on a hotplate. I’ve been meaning to make the design files available somewhere, but some fixes are needed (the balun pads are too small, making it difficult to get enough solder on them for the balun).

        Ok, thank you for the answer.
        W’ll try to build my own board or maybe use the one from dresden electroinc.
