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:
Support for the IDE 1.0+ (OSX / Win / Linux)Power via USB or External Source – 5v or 7-35v (automatic selection)On-board 500ma 5V RegulatorBuilt-in USB (and serial debugging)6 I / O Pins (2 are used for USB only if your gram actively communicates over USB, otherwise you can use all 6 even if you are gramming 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 pinsPower LED and Test / Status LED (on Pin0)
