I want an ATmega32U (or 328) in the form factor of a USB key

I want an ATmega32U (or 328) in the form factor of a USB key – especially the built-in USB male plug.
Sort of link a 'blink(1)", but with an ATmega instead of an ATtiny. The key things I’m looking for are: compact form factor, durable casing, “full” ATmega chip, and no cables required. Whether it has any LEDs on it or not is almost immaterial; I just want this for development, testing, and performance timing/optimization runs – it doesn’t have to actually have any LEDs or exposed pins (though that’d be an interesting option).

Thoughts? What do you think, @Tod_Kurt ? “Blinkduino”? I suspect there’s close to zero market demand, so I’m not terribly serious about this. Maybe this should be one of the hardware designs in the new (imaginary) “FastLEDuino” line, the “FastLEDuino Key”.

Arduino pro micro?

It’s not just the smalless that I want. It’s the no-cable-required. Think about how you plug a USB key into a computer: no cable. It just has the USB plug on the end of the device itself. That’s what I want here. A USB “key” with an ATmega inside it.

Check out blink(1), to get an idea of what I’m thinking. http://thingm.com/products/blink-1/
It would be perfect, except that it’s an ATtiny45 (I think) instead of a ‘full’ ATmega32U4/328.

Someone mentioned the “beetle” before in here:

It has a 32U4 chip, a very small form factor and a USB micro plug.

…but it does not have a male usb plug :frowning:

Freetronics Leostick http://www.freetronics.com/products/leostick

It should fit the bill, right down to the ‘no cable required’ :slight_smile:

ATMega32U4, 2xRGB leds (meh), same header config as ‘normal’ arduino (albeit shrunk)… has polyfuses et al as well…

Uses similar trick that used to be common to edge-solder old DB-XX connectors - It has from memory 2 x 1mm substrates to give you a 2mm board with gold fingered edge contacts to ‘mimic’ a male USB plug using the PCB substrate alone…

It in itself doesn’t have a ‘durable case’ - but it is the same form factor as many key-type devices, or you can 3D print one darn easily…

Hey! That’s great. I had bookmarked it a while back and totally forgot… Thank you!

Basically redesign a Trinket with a PCB USB Type-A connector. Or take a 23U4 and do what Freetronics did.

Like a digispark, but 32U4…

Fwiw, I ordered a LeoStick. Maybe I’ll encase it in sugru. Or epoxy. Or nougat.

Well yeah, Digispark with a 32U4 = Leostick. :slight_smile:

But I don’t want the LeoStick’s female headers. Just the flat board. Keychain style. And maybe some LEDs. Or a 3 or 4 pin JST connector on the end for a strip. Or nothing really. I seriously just want an Uno/Leo in the form factor of a USB key, all sealed up in plastic so I can compile, run, and time AVR ATmega code for dev and test and profiling/optimization purposes. I suppose I’d be happy enough if there was a cycle-accurate simulator that run under OSX.

And then I want the same thing, but for a Teensey 3.x. :slight_smile:

No pony, though, but thanks for offering!

I bet the LeoStick + sugru does the trick.

Doesn’t the LeoStick come disassembled? At least one of the pictures seems to show that. So you don’t have to put the headers on if you don’t want them …

HA!! Yes! Sure looks that way!
Well, lucky me!

You can also pop the piezo on the underside and cut its jumper track if its thin form factor you really want

EDIT: And yes, they come without the headers attached

I would be interested in this too. Those 5v rechargeable, 2.1amp battery packs are a great way to easily power my projects. A micro controller with a male USB that could power the LEDs and controller, would be great. @Ashley_M_Kirchner_No Do you think you could work some magic on this? hehe

Sure, I’ll get right on that! :slight_smile:

Honestly, the bigger issue here is trying to figure out what to break out. Breaking out all the possible pins would add to the board size. Breaking out just a few would mean figuring out which few. Some might want these pins, others might want those, and yet someone else might want the ones over yonder … So yeah …

How about a custom FastLED , community design? Any takers?

I don’t mind creating a custom (FastLED) controller. The problem I see is that everyone will have their own, custom, requirements. :slight_smile:

But, if the desire is there, I’ll gladly initiate a project on my end and open a forum for people to put down their wishes.
