Microduino: An Arduino nearly as small as a quarter, for $20

- throwaway1979 13y agoI asked the same question yesterday ... how is this different from Tiny Circuits? I got a set of these and Tiny Lily at Maker Faire this weekend. Those seem to be the same size. There is no ethernet shield for Tiny Circuits but is there a fundamental difference? Also, side note, was there a recent technical innovation in manufacturing that so many small form factor boards are popping up everywhere?
- jeroen94704 13y agoI don't think there is anything fundamentally different between _any_ of the *duino boards, apart from the form-factors. That is one of the interesting aspects about the Arduino ecosystem though: its diversity. IMHO, the Microduino system looks like a collection of awesome little boards that are extremely modular. And yes, that is pretty similar to what the TinyDuino offers. So what? The most powerful aspect of the Arduino is not the boards anyway, it's the software platform with the incredible number of libraries that makes it dramatically easier to program the atmega328 and its relatives. In fact, I have never bought an actual Arduino board, but alway rolled my own. But I'm still using the Arduino IDE, even though as an editor is sucks, simply because the libraries make life so much easier.
- throwaway1979 13y agoIn case it came out wrong ... I'm not complaining about novelty. I'm merely wondering if I missed something given that so many news outlets are talking about it :)

- mmagin 13y agoLooks like you have to ISP program that one, and not even with a standard ISP pinout.
- fnordfnordfnord 13y agoYou just need an USB -> RS232(5V or 3.3V) such as an FT232R or other.
- mmagin 13y agoOh, I see. They still didn't use the defacto standard FTDI header pinout however.
- fnordfnordfnord 13y agoNo, and you might have to reset it manually for upload, like some of the early and other barebones Arduino versions (instead of relying on the CTS reset trick).
- mikeash 13y ago$9, even smaller: http://digistump.com/products/1 http://digistump.com/products/1 And it does USB directly, no need for any additional hardware to talk to your computer. Extremely CPU and memory constrained compared to a typical Arduino, though. Only a few kB available for your program.
- veemjeem 13y agoI'd take the femtoduino over the digistump in this case. The atmega328p is vastly superior to it's low pin cousin, attiny85. I'm sure you could engineer the atmega328p to also talk directly to usb as well as it's merely using the V-USB project.
- ChuckMcM 13y agoHoly smokes. That is a fairly complete set of modules / boards.
- leokun 13y agoCurious about if the "duino" part of the name is a little too similar legally wise.
- fnordfnordfnord 13y agoNote that while we don't attempt to restrict uses of the "duino" suffix, its use causes the Italians on the team to cringe (apparently it sounds terrible); you might want to avoid it. (It's also trademarked by a Hungarian company.) It is covered here: http://arduino.cc/en/Main/FAQ http://arduino.cc/en/Main/FAQ Clones and fakes: http://blog.arduino.cc/2013/07/10/send-in-the-clones/ http://blog.arduino.cc/2013/07/10/send-in-the-clones/ As far as I can tell, they tend to focus more enforcement effort on companies who sell sub-par ripoffs and defects as genuine. It looks like stamping them out is a full time job.
