 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. |

Man you were Talking about how Useless the idea of an Arduino form factor picomite was, but you did it for me anyway :) and I guess I'm not the only one that finds Value in an Arduino Formfactor Picomite Rick I may be Vulgar, but , while I'm poor, I'm Industrious, Honest, and trustworthy!

Copycats. ;) I stick by my argument though. It's a stupendously awful mechanical design for a hobbyist experimenter. They seriously broke the whole concept and there's no going back now. PCB components and connections have been on a 0.1" grid for a generation, why screw it up? I'm almost tempted to think that the person laying it out was inexperienced and made it "look right" without checking that it worked properly. The Raspberry Pi is also a pretty stupid mechanical design to my mind simply because there are few ways to use a twin row GPIO port without using a PCB. However, the Raspberry Pi is designed as a computer with an add-on GPIO port and not as an embedded controller. The concept is different so there are mitigating circumstances.

The story goes, it was originally designed as a simple device to be used in teaching sessions, deliberately designed with a different spacing so that the boards would not fit other systems and thus not go "missing" so much, ha ha.. |

That's quite possible, or it might equally well be a fabrication to cover up incompetence. lol I'm not sure that the "going missing" would have been affected much by a non-standard pin spacing though. If they'd wanted that it would have been better to make it A4 size. :) Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

I could use a board like that with vero/strip board as a hat, if the sockets are same pitch as rpipico board. I can see an ili9341 on strip board and the board plugging in but soldering a row of pins to the UNDERSIDE of stripboard is more effort than the component side. If £10 I'd be happy. |

I'va already designed the ArduinoMite_S, which is a PicoMite-based near-Arduino with everything including the fixing holes on a 0.1" grid. It's ideal for expanding with stripboard and padboard "hats". Probably best used with double-sided padboard. No use to you because it's a pcb of course. ;) Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

This is the story I stick with when anyone asks... and I do remember that they DID admit to having an OOPS moment... but so many boards were fabricated they just stuck with the error and called it a feature. Edited 2024-07-20 03:18 by pwillard |
