A have a couple of projects in the planning phase that involve adding custom hw to the gumstix via the 60 pin Hirose connector. In the past I've prototyped using a tweener, breakout gs, and flying blue wires to a prototyping board. It works, but it's not pretty and the physical stability leaves much to be desired! I'm going to bite the bullet and do a somewhat general purpose 60 pin prototyping PCB. At a minimum it will combine the functionality of the tweener and the breakout gs and include a prototyping area (.1" grid of through holes). Before I proceed though, I thought I'd check to see if anyone on the list knows of the existence of something like this. If not, feature suggestions are welcome. Perhaps I can find a way to make the boards available to others. Steve |

We have been talking about this internally and would be happy to do the board/boards: our internal products have been designated: breadstix (more-or-less simple breadboard design) dipstix (DIP carrier), and protostix (a more sophisticated set of traces and interfaces than thebreadstix) Would you like to work with us to spec and we can build, or would you rather carry it out yourself? Could I suggest doing it with the mailing list and incorporating the list's feedback, much the way we did with robostix?

We've been evaluating gumstix for an industrial application. While we've been mostly happy with its functionality, my vote today would go against using it. Small size is good, and the size of the current board for some applications is a real plus. For ours, its a pain in the a**. While its ok to have to solder bits off the side and find an appropriate solder track to get VCC from etc. for a one-off project, for even modest volume deployments this becomes a deal breaker. The shear labor cost of doing this (in time and/or money) and the hobbyist appearance of the result means its probably better to just buy a pc/104 board. My suggestion would be to think about a version of gumstix that may be 3-4 times as big but brings out the functionality in pads that accept common connectors, already has a reset switch and a couple of leds and, as trivial as it may sound, has 4 mounting holes of a size that accommodates common standoffs and screws. Such a board could serve as a prototyping board but would have utility beyond that, and would open new markets for what is otherwise a really good product.

Jim, We're thinking along the same lines. I'm envisioning a board about 3" x 5" with mounting holes for the gumstix as well as in the four corners :-) I ended up doing a custom pcb for my current project in a configuration very similar to this. Seeing the result is what gave me the notion to do something a bit more general purpose for prototyping future projects. The dipstix idea is cool for "one off" protos on 3M solderless breadboards, but doesn't fly if you need to build more than one or require mechanical integrity.

Gordon, I'm open to either option. Collecting input from the list is a good starting point. Let see what people are looking for and take it from there. If there seems to be general consensus on a feature set then it certainly makes sense for Gumstix to do it.

What I did was cut up an old IDE cable and solder the bare ends to the breakout-gs. The 40 pin female connectors act like mini breadboards; 22g wire plugs into them just fine. |

I really like the idea of a dipstix. Something that has 0.1" spaced headers where you can solder in some pins and plug the whole thing into a solderless breadboard. Using machine pins (which are round), instead of the square ones, makes it easier to insert/remove from a solderless breadboard. These are the kind of pins I'm referring to: <http://www.sparkfun.com/commerce/product_info.php?products_id=117> It would be good to have a voltage regulator (like on the rest of the boards), but have a way of bypassing it, for people wanting to play with batteries and whatnot (so identical to the power on the breakout-gs). I don't think I would put any other circuitry on it, unless the circuitry could be bypassed (buy say removing a zero ohm resistor). I think it should have 60 pins on it that map 1:1 to the 60 pins on the hirose connector. Since the standard gumstix is 80mm = 3.14" this should be able to all fit. 3" per side allows 30 pins/side. -- Dave Hylands Vancouver, BC, Canada http://www.DaveHylands.com/ |

My solderless breadboard will accommodate a maximum DIP spacing of .900" . This allows room to connect one wire per pin -- not ideal, but livable. The gumstix width is also approximately .9" which brings the possibility of interference between the tops of some of the machine pins and gumstix components. This is probably fixable with a pair of snips if it turns out to be a problem :-) The next issue comes from the fact that the board will need to extend beyond the .900" spacing of the machine pins (another .050 or so) This will encroach on the space for that one wire per pin on the solderless breadboard. Again, not a deal killer, but probably an annoyance every time you use it. The final potential issue is the size of the board. I did a couple of trial layouts. To get a nice clean 8 mil lines/spaces layout with no vias(!) and 3 mounting holes for the gumstix requires a board size of 1.00" x 3.75". The long end of the gumstix will extend about .65" beyond the edge of the board. It's also possible to shrink the long dimension down closer to the actual gumstix size by using 6 mil lines/spaces and lots of vias. Does this still sound like something folks would want? It's feels kludgey enough that I'm leaning more toward building a 4" x 6" board with prototyping area plus power input, RS-232, and USB. Steve |

Hi Steve, > My solderless breadboard will accommodate a maximum DIP spacing of .900" . > This allows room to connect one wire per pin -- not ideal, but livable. Yes - I see what you mean. I also have some double solderless breadboards, and the spacing between the boards is a bit wider. > The gumstix width is also approximately .9" which brings the possibility of > interference between the tops of some of the machine pins and gumstix > components.

It is for prototyping after all. I think that having the RS-232 and USB would be good, especially if they're jumpered and the functionality can be disabled by pulling some jumpers. -- Dave Hylands Vancouver, BC, Canada http://www.DaveHylands.com/ |
