ATTiny85 USB Development Board

The ATtiny85 based mini development board is
similar to the Arduino, but cheaper and smaller (of course a bit less
powerful). With a whole host of shields to extend its functionality and
the ability to use the familiar Arduino IDE, this board is a great way
to jump into microcontroller electronics.Product Specs:
