Great little board
For Development board Nano V3 Arduino compatible
I ordered the Nano compatible board from this seller in order to use with this project: https://github.com/qu1j0t3/gpib-adapter
The board has performed flawlessly and I recommend it. Based on that experience I've gone ahead and ordered ATtiny85 boards as well.
There was only one small gotcha with USB drivers on OS X. I had to install the third party driver for CH34x. e.g. https://github.com/adrianmihalko/ch340g-ch34g-ch34x-mac-os-x-driver
