A few days ago we saw what would have been a killer Kickstarter a few years ago. It was the smallest conceivable ATtiny85 microcontroller board, with resistors, diodes, a USB connector, and eight pins for plugging into a breadboard. It’s a shame this design wasn’t around for the great Arduino Minification of Kickstarter in late 2011; it would have easily netted a few hundred thousand dollars, a TED talk, and a TechCrunch biopic.
[AtomSoftTech] has thrown his gauntlet down and created an even smaller ‘tiny85 board. it measures 0.4in by 0.3in, including the passives, reset switch, and USB connector. To put that in perspective, the PDIP package of the ‘tiny85 measures 0.4 x 0.4. How is [Atom] getting away with this? Cheating, splitting the circuit onto two stacked boards, or knowing the right components, depending on how you look at it.
[Atom] is using a few interesting components in this build. The USB connector is a surface mount vertical part, making the USB cord stick out the top of this uC board. The reset button is extremely small as well, sticking out of the interior layer of the PCB sandwich.
[AtomSoft] has the project up on OSH Park ($1.55 for three. How cool is that?), and we assume he’ll be selling the official World’s Smallest Arduino-compatible board at Tindie in time.
For the world’s largest Arduino, how about one made entirely out of discrete components? It would cost a fortune to design and build…
but would be truly amazing and worthy of a friggen metal … it would be AWESOME to have LEDs all over it to see it in action
Led, pfhhh… Light Bulbs :)
Build it with diode logic, used LEDs for the diodes.
Diodes? um, no. Relays.
Mechanical arduino.

Seems like this didn’t makke it any smaller, just different shapes. I don’t know about you guys, but I measure size by volume, not footprint.
For use on a breadboard footprint is what matters. Using vertical USB connector is absolutely brilliant since the USB cable covers part of the breadboard when mounted in a horizontal connector. The ‘tiny85 PCB is a bit smaller in total area and hence cheaper ($0.95 vs $1.55) but you will need to hack the PCB to build it. This design is much cleaner.
If you’re working on a breadboard does size really matter? If your breadboard isn’t big enough, get a larger one.
soon to be bricked by the ftdi update……..
sorry I could not resist
There is no ftdi onboard ….
And the FTDI update only bricks fake driver chips anyway.
sooo, only 90% of FTDI chips will break?
lol
World’s largest Arduino might be a Virtex-7 with 2K balls and 2M LUTs running more than a thousand AVR8 cores at a few hundred megahertz each. That would be quite an achievement on the ‘because I can’ front. Any batters stepping up to the plate? (or willing to send me a V7 EVM!)
How about an arduino built from crap? Finally this shitduino crap would stand for it’s name.
LOL run along ragenerd. WAAA WAAAAA ARDUINO WAAAAA!!!!!

..worlds largest arduino dick sucking contest?
hahahaha
Don’t know about bigger, there isn’t much challenge in that, but I suspect I know a man who can probably make it even smaller … https://www.youtube.com/channel/UCNAAxVKWPAbaZiB90_kjDJw .. I wonder if he is up for the challenge.. Alternatively, do you think it would be possible to fit the processor inside the shell of the USB connector…. or use flat flex instead of rigid pcb material… just a couple of possibilities…
LMAO i remember that guy. The only way to make this smaller is to decap it probably. But since i cant do that (yet) perhaps someone else can but then its not really mass produce-able. How about buying the DIE straight from Atmel? Would be cool!
I have a design for a smaller one that only uses one PCB and is no taller than the original DIP. Will post it soon.
It has to include button and USB connector. If not then it doesnt count.
Right, I figured that. I am being liberal with the definition of “connector” though.
