There is no way to order a jModule. You can build it yourself. First you need to find a PCP manufacturer and order a few jBoards. I am form Poland. Here in Poland I can recommend: Satland Prototype
Next follow the build instruction - 10 minutes of soldering and your own jModule will be ready. It is really easy to build. The hardest part is to solder a voltage regulator - use method pin by pin.

jBoard2 arrived............jModule2 is coming
