What is it?

This is a very simple breakout board to add USB capabilities to an attiny85, for example. The board is very simple and follows this schematic: You could, for example, flash the digispark bootloader on an attiny85 and use this board to rapidly test the USB part of your project (like the 3rd product picture). This is, however, not limited to attiny's and the digispark's bootloader. You coud use any fast-enough microcontroller-- For example, the V-USB library

Why did you make it?

There is no specific reason why I made it, it's just very nice to have breakout boards to have on hand for testing parts of projects.

What makes it special?

I didn't find one while doing my USB related projects, so I made it.
