       | Great tutorial.

       | I'm currently making a new type of MIDI controller, based on an
       | Arduino Uno; I have been iterating on prototypes with different
       | sensors. It's not very difficult (or time consuming) to solder
       | the prototypes so they're a little more durable than breadboard.
       | 
       | Eventually I would like to make an integrated product that could
       | be manufactured in small batches; but what is the benefit of
       | doing an intermediate PCB using breakout boards? It seems all the
       | real problems will come later when moving from breakout boards to
       | single components?

         | It definitely depends on what you are building and what you are
         | trying to validate. I use this sort of board to do product
         | validation with early customers. It's much easier than
         | producing the full DFMed board, and sometimes it's much faster
         | & reliable than something soldered together. For reference, on
         | my Thermostat project the green hand wired project board took
         | probably 2 hours to assemble, the PCB motherboard takes about
         | 10 minutes.
         | 
         | It's also great for producing a couple boards when working with
         | other engineers, I can more easily guarantee that we are
         | working with the same hardware setup because all of the
         | connections are made on PCB.

       | Isn't the free version of Eagle limited to 2 layer designs?

         | Ah, that is correct. I guess I didn't realize that. I've used
         | it since it was a free project. I'll update my post accordingly

       | This is great, and timely for me. I've got some horrifying rats-
       | nest prototypes in the field that I've been really wanting to
       | replace with PCBs.
       | 
       | I'm looking forward to part two about doing the layout. That's
       | the part where I get flummoxed.

         | That's exactly where I started when I learned how to do this,
         | glad it could help. If you have any questions about your
         | project specifically feel free to hit me up, I love talking
         | about this stuff
