 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

What the world needs is a MicroMite on an Arduino Shield ..... with included USB connector Gives access to the hardware of Arduino platform to BASIC users |

Amazing no-one else has suggested that yet.  Nice one. 
That would be easy to do. All you need is the Arduino footprint. Like the Arduino, the Micromite has I2C, Serial, and GPIO pins, so it should be quite simple. I will work on designing a layout, which I will upload here. EDIT: Do I assume you mean a Micromite platform, with an Arduino shield footprint, so you can plug in standard Arduino shields and control them from the Micromite? ...I think that is what you were getting at.... Smoke makes things work. When the smoke gets out, it stops! |

Gotcha. 
This is the first pinout I found: 
...and these are the dimensions I have found:

Grogster, Those sizes CANNOT be correct.. the difference between the 62.5 and 48.8 is 13.7mm which is 0.54" given the RH connector is 0.7" long it cannot be.. I have the dimensions around somewhere I will try to dig them out for you. Mick Mick's uMite Stuff can be found >>> HERE (Kindly hosted by Dontronics) <<< |

If you have a colour maximite, you can get the measurements from there. Jim VK7JH MMedit MMBasic Help |

Grogster, Here are the correct dimensions for the Arduino connector.. Note that there is also an `incorrect' version that has the RHS gap as 0.15".. Whilst this is not quite the original spec they are close enough that they will work.. If you were going to do an Arduino style board I would use the correct 0.16" gap. 
Also beware, as whilst it sounds a great idea, it has been done with the Duinomite range and Colour Maximite and the DonDuino Cross PCB and I really do not think that the Arduino footprint with any of these were popular and that very few were actually used with Arduino shields installed.. It wasn't seen as all that useful, for some reason or another. I, personally, do not agree with that but that is how the market saw it. Many criticisms were because of the speed of basic.. That `may' now be different with CFunctions but think carefully. Also the Arduino footprint is not all that user friendly IMHO it could be better to create your own bus and build add-on boards for it.. Anyway good luck PCBster Mick EDIT ** I see the distance between the rows is also different in your picture They have it as 50.5-2.54 or 47.96mm whereas it should be 1.9" or 48.26mm Mick Mick's uMite Stuff can be found >>> HERE (Kindly hosted by Dontronics) <<< |

With so many modules (SparkFun, seeedstudio etch,) available that do not use the Arduino shield I see not much use in yet another platform adopting a wrong layout. Only for the simple reason that it is not on a 0.1" grid. Some things should just die a slow death and the Arduino shield is one of them. Microblocks. Build with logic. |

I tend to agree TZ, It would be better to adopt a 50mm x 50mm format to take advantage of the cheap PCB Fab houses deals for that size.. Arduino is an awkward size and the pins do not fit a 0.1" proto board and if you needed a simple sensor why use all that PCB real estate for it.. On the other hand there are a lot of pre-existing shields out there.. But I still believe it wont be a well utilised feature ..

LOL! 
I might put this on the back-burner then. Not much point, based on members' comments. It is dead easy to run wires from any Micromite, to the appropriate pins on any Arduino shield, if you desperately need to use a shield for something.... Smoke makes things work.

Perhaps the simplest way would be a daughter board that plugs into the Expandamite or BigMicks MuC with a pin layout to suit the Arduino. Just a thought Cliff Cliff |

Just to add my twopence worth, I have used the arduino prototype boards available from jaycar at around 4 bucks and this may be a compromise for those who would like to use shields and the micromite.

Even better a daughter board to plug into Grogsters new VT100 + micromite board, then you have it all. Cliff Cliff |

Yes, the reason for the three rows of connectors on the VideoMite, was so that you could design a daughter-board for it, if you wanted. Smoke makes things work. When the smoke gets out, it stops! |

Grogs, Don't let me dissuade you away from this idea, I have only given my thoughts.. Others like Hitsware and Centrex seem to want an Arduino connector and I am sure there will be others as well. I think one of the flaws with Arduino is that each shield basically has one purpose and to combine many different features requires a healthy stack of Arduino boards (all of different sizes). I think a board that accepts the standard Arduino sensors and motors etc would be a VERY worthwhile addition, indeed one I have been thinking of for MuP. If you search on FleaBay for Arduino you will find that the term itself seems to have morphed into something that means `micro electronics' as most items that are listed are not Arduino footprint at all and the ones that are are generally Microprocessor boards. My suggestion is to research the various connectors for the various `add-ons' and try to fit them to a PCB, that might be more beneficial in the long run. Still that is just my 2c worth.

Lets do a very basic poll here. Please post YES or NO as a post on this thread. You do not need to give reasons. Based on member interest, I can certainly whip something up if it is something more then one member would want - with no disrespect to the OP in any way whatsoever. Smoke makes things work.

Actually I'll be releasing a board like this in December. (I knew all the correct measurements as the CGColorMax2 uses shields.) Micromites and Maximites! - Beginning Maximite |

I was thinking it could be BIG outside of just members, but I bow to those more knowledgeble. I'll use a protoshield (I've now a better selection than on my previous attempt) Let the world suffer  |

Unfortunately, I am not a big fan of the arduino footprint. I agree with Mik on this one... quote... I think one of the flaws with Arduino is that each shield basically has one purpose and to combine many different features requires a healthy stack of Arduino boards (all of different sizes). The MUP V2.0 is a great little board for connecting to things while experimenting. Once the design is done, I will tend to just get a pcb made for that particular application. I have also successfully used the WW44pin board for applications that require more i/o pins. This is great for experimenting and designing also. The videomite board will be nice for this also. |

Or get one from CircuitGizmo .... How soon in December ? .... Got the new type MicroMites ? |
