Seems to be a new offering by them, in 3V and 5V versions -

Given that you have only a few pins, making a board for it doesn't seem to be that efficient.
Programming the naked chip may be a better way to go.
-
$8 is pretty much for something intended to be a throwaway/jellybean part.
-
Not sure how long people would bother with the old V-USB LOW SPEED AVR platform when today you can get native FULL SPEED USB support in a 14-pin PIC that is cheaper too and only requires two caps. Even the existing PC side code can be reused with little or no change.

I have a few minimus: at90usb162, with more pin out, native usb, etc. for $7/each.

Cute. Are those still around? I can only find the "minimus 32", and only from UK-based stores...

I am not sure. I got mine years ago.

How about just a Tiny 2313 soldered directly to an LED Matrix?

I don't get that impression here, $8 is rather expensive for a PCB that has not much on it.
But then again almost everything Adafruit sells is amazingly overpriced...
-
Well, they do contribute a lot of documentation and stuff so in a way, you're paying to keep that going.

That's what I meant, the phrasing just got mangled.
-
Personally I would just go on digikey and spend the $1.18 for an attiny85 and use it direct, but there are those that find a pre-made board useful, to each their own :).

You can do this also:

Yes. And there should definitely be a substantial discount to compensate for the pain of using the arduino ide, :)
-
Nothing stopping anyone from using Atmel studio.
-
Check out the new STM32F429 Discovery.
-
They also announced a board called the Gemma which is basically a small Flora board based on the Tiny85.
-
This thing is just a ripoff of the digispark that I bought on Kickstarter last year!
I didn't think Adafruit would do something like that...
-
I'd hardly call it a ripoff. Adafruit appears to just have taken an existing product that they have and shrunk it to an ATtiny85.
And even if they did, the Digispark has the Open Hardware logo on it anyone can rip it off.
-
Hard to call it ripping it off when it's only an attiny85, some bypass caps, and a USB connector ;)
-
I guess "rip off" was a little extreme...
Reminds me of the Digispark that I bought on Kickstarter...
-
The only one being ripped off is the customer... ::)

Absolutely. With $7.99, you could have gotten LM4F120XL from TI; or buy a few of the bare chips ($1/each?).
$7.95 for a 8pdip chip is a lot of money.
