5. USI – Universal Serial Interface (12C, SPI, 1-wire) with Start Condition Detector
6. 10-bit ADC
7. 4 Single Ended Channels
8. Two Differential ADC Channel Pairs with Programmable Gain (1x, 20x)
9. Low Power Consumption
10. Active Mode:1 MHz, 1.8V: 300 µA

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. Applications: Support for the Arduino ide 1. 0+ (osx/win/linux). Power via USB or external source - 5v or 7-16v (automatic selection). On-board 150ma 5v regulator. Built-in USB (and serial debugging). 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 boot loader) i2c and spi (via usi) pwm on 3 pins (more possible with software pwm) a DC on 4 pins power LED and test/status LED.
