Digispark ATtiny85 Development Board

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.

Specifications:

• Support for the Arduino 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

• Built-in USB

• 6 I/O Pins (2 are used for USB only if your program actively communicates over USB, otherwise you can use all 6 even if you are programming via USB)

• 8k Flash Memory (about 6k after bootloader)

• I2C and SPI (vis USI)

• PWM on 3 pins (more possible with Software PWM)

• ADC on 4 pins
