DigiSpark uses the ATTiny85 chip, and was originally a Kickstarter.
When it came on the market (2012?) it was about the only easy implementation of an ATTiny for Arduino. Since then Adafruit came out with its Trinket, which appears substantially similar, performance-wise, though DigiSpark is about 1/2 the price of the Trinket, and the DS has a whole line of stackable shields.
- Specs:
- 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
- Power LED and Test/Status LED
------------------------------------------------------
Note: the rev. 4 (Model A) pictured above uses P1 (pin 1) for the onboard LED. Rev. 2 is Model B, and uses P0 for the LED. Rev. 3 is an unsupported counterfeit, as Digistump has never made a rev. 3.

Note: the Digispark-USB pictured above has an on-board micro USB port, but this board may be an unlicensed clone, because there is no documentation about it on the Digispark site, however it seems to work just fine. The board is marked "ATTiny85", with standard 6 I/O.
-----
Note: the Digispark Pro pictured above is an entirely different animal, with a different MPU (more I/O).
-----
Note: the Digispark does not support Serial monitor like other Arduino boards. See forums and wiki for workarounds.
