@NeverDie The differences:

• 2 build options
• no SMD elements (AMS1117 replaced by LE33 - TO92 package)
• smaller size: the jModule and the jBoard
• I/O pins in a one row

@chsw The "by link" I think will be soon. The latest revision of the project waits for verification by manufacturers (I do not know why it took so long, the project is available for a moth ago).

jModule2 is ready :)

The improvements:

• 2 build options
• no SMD elements (AMS1117 replaced by LE33 - TO92 package)
• smaller size: the jModule and the jBoard
• output pins in a one row

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

@m26872

Unsolder USB connector and instead of the connector use wires to connect the jModule.

I do not care about the power. I use USB wall charger to power my nodes. I can recommend this model (it is almost the size of jModule after removing the case):

Hi, my be this film will help you: How To - Duplicate Your PCB Layout Design in Eagle.

@bjacobse
Here you can find The instruction of creating GERBER production files
I also added gerber files to the project.

@dakipro
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.
