I'm interested to hear whether folks think this is a useful idea. "Breadboard Helpers" are a small pair of breakout boards designed to make breadboarding an Arduino-compatible quick and easy. I like to work on breadboards, but it gets tedious and time consuming putting the MCU "infrastructure" in place. These allow me to get to the "real" part of the project sooner, keep things neater, and maximize space available for other circuitry.

The "Before" picture is as compact as I think I can breadboard the individual components; not much room left on a small breadboard. "After" is with my prototype Breadboard Helpers.  All comments appreciated.

Well that is certainly different then any other approach I've seen. Nice thinking outside the box.  ;)

What about a single PCB with all the stuff on it and a DIP socket for the ATmega in the middle? The whole thing can then be plugged into a breadboard and still allow access to all I/O pins at the outer edges of the breadboard area.

That's a pretty good idea, I like it.

Question: Could you make the helpers a bit larger to provide "some personalization"?
e.g. some people want an DS1307 in every sketch or some LED's showing the state of the digital IO lines (like serial breakout box)

Or the Boarduino (which I'm a big fan of) which has the added feature of a built-in power supply. Although I also like the little breadboard power supplies that Adafruit and Sparkfun sell.

No reason it couldn't be done (I assume space perpendicular to the breadboard is unlimited, yes? ;)) Hmm, I may be one of those DS1307 people ... now why didn't I think of that??!! :D  LEDs are a good idea, there again a common thing we do repeatedly, taking up space, dropping resistors, etc. I did start sketching up a board with a few 6mm tactile buttons, darned things want to keep popping out of the breadboards sometimes.

One goal with these boards was to not take up more breadboard space than necessary, electrically or physically. They do take up one connection point on several pins that they don't in fact connect to, namely 4, 5, 6, 15 and 16, but there's still three points left for each so I thought it a good tradeoff.

You can always for a dead bug style arduino.

I like it, that's a cool setup.
How does it compare price wise with a BareBonesBoard (my personal favorite, or at least tied with the RBBB)?

JChristensen

The two breakout boards including the parts that go on them could be sold for $7 or $8. Adding the ATmega328, but not the breadboard, would probably come in somewhere between the BBB and RBBB. I'm not set up to sell them at this time, but have been toying with the idea of a small run of 50-100 kits, maybe as a little income opportunity for my son.

I don't have a feel at this point whether that would be a viable venture, or whether there would be more interest in the boards and parts only, or if the ATmega328 and/or a breadboard (small or large) should be included ... feedback welcome!

Either way I'll make the Eagle files available, although I may have one or two small tweaks to make when I get some time. Thanks for your interest!

Contact Rugged Circuits, he has a shop and might be able to help sell them ...
Or Terry King, he has a shop too

Sounds more like a Sippino.
