Attiny85 USB Development Board Support for the Arduino IDE 1.0+ (OSX/Win/Linux)
– Power via USB or External Source – 5v or 7-35v (automatic selection)
– On-board 500ma 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 bootloader)
– I2C and SPI (vis USI)
– PWM on 3 pins (more possible with Software PWM)
– ADC on 4 pins
– Power LED and Test/Status LED (on Pin0)

The Digi spark is shipped fully assemble except for the two included and easy-to-solder headers.

Attiny85 Digi spark USB is the smallest Arduino compatible development board so far. Originally develop under the name Digi spark and release under open source license. It has 6 port with several functions. Depending on the programming (with Arduino IDE) can it have 6 digital I/O, 4 analogue inputs or 3 PWM outputs. It can be power by a USB port or an external power supply of 6-35V DC.
