Product Details
The Digispark is an Attiny85 based microcontroller development
board 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.
