ATtiny85 USB Digispark Developing Board
Series ATtiny (AVR)
ATtiny85 overview
USB Digispark ATtiny85 Developing Board-based microcontroller development board. ATtiny85 Developing Board is similar to the Arduino 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 Arduino IDE, the Digispark is a great way to jump into electronics, or perfect for when an Arduino is too big or too much.
The Digispark is shipped fully assembled except for the two included and easy-to-solder headers.
