There seems to be some confusion on this. Is the PXFmini discontinued or still "in production"? I hope the latter. Reference closed topic http://forum.erlerobotics.com/t/is-the-pxfmini-being-discontinued/4542
Right now the PXFmini is discontinued..
Is there a new version coming out? Any old stock left? Are the board designs and software available to homebrew them?
I'm sorry to tell you but right now there wont be any...
