content: 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.

content: 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.

content: Quote from: andersm on September 10, 2013, 04:17:38 pmI 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...

content: 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.

content: 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.
