I have built a small IoT application that runs on my RP. I would like to deploy it permanently in my home, but would like to formalize the breadboard setup into something a little more durable and lasting. What is the right way to do this? Is there a preferred case that allows for screw terminals or perma-proto shield? I would like everything to be as compact as possible.

I am happy to solder as needed.

  • I'd have thought solder is by far the best for permanence (although some might say wire-wrap). It's not really a question for this site though. – joan Dec 18 '15 at 22:46

There are several options that very in flexibility, cost, difficulty etc.

My preferred method is to use a Pi Cobbler and a PermaProto Board from Adafruit. You could prototype with a breadboard and then transfer the components to the protoboard and solder the connections to make it more permanent (note there are more suppliers for these parts besides Adafruit, also I linked to the full size protobaord but it does come in smaller sizes).

You could carefully solder wire to the GPIO pins themselves - though I would not recommend this.

You could wirewrap the connections (this is the old school method and requires a special tool.

You could create a custom PCB, (either make it yourself or have it manufactured by a company like OSH Park) (when having it made this usually requires a minimum number of boards to be purchased and can be daunting for someone who has not done it before.

Depending on the environment you could just leave it on a breadboard with jumper wires.

  • Thanks, I found this adafruit.com/products/2310 plus some screw terminals to be exactly what I'm looking for. – John Dec 18 '15 at 23:51
  • One minor thing I'd add: soldering to the GPIO pins is indeed a bad idea on the original Pis, but on the new pi zero it's quite a reasonable proposition (given the cost of the unit it'd be feasible to buy one per "permanently deployed" application - a colleague has already done this with a unicorn HAT and a pi zero attached to a Babbage bear :-) – Dave Jones Dec 19 '15 at 9:00
  • @DaveJones good point as it ships without headers you could solder right to the pads. – Steve Robillard Dec 19 '15 at 9:06
