Brand new and high quality
The Digispark is an Attiny85 based microcontroller development board similar to the Ar-duino line, only cheaper, smaller, and a bit less powerful. With a whole host of shields to extend its functionality and the ability to use the familiar Ar-duino IDE the Digispark is a great way to jump into electronics, or perfect for when an Ar-duino is too big or too much.
The Digispark is shipped fully assembled except for the two included and easy to solder headers.
Here are the specs:
Support for the Ar-duino IDE 1.0+ (OSX/Win/Linux)
Power via USB or External Source - 5v or 7-35v (12v or less recommended, automatic selection)
On-board 500ma 5V Regulator
