Digispark is an ATtiny85 based microcontroller development board come with USB interface. Coding is similar to Arduino, and it use the familiar Arduino IDE for development. Make the Digispark an Arduino compatible development board, plug it in, power your project with USB or external sources, program it with the Arduino IDE, and easily use existing Arduino code! At the same time with its small size and low cost, you can feel free to leave it in your project, give one to a friend, and use them everywhere!

1. Support for the Arduino IDE 1.0+ (OSX/Win/Linux)

2. Power via USB or External Source - 5v or 7-35v (automatic selection)

3. On-board 500ma 5V Regulator

4. Built-in USB (and serial debugging)

5. 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)

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

7. I2C and SPI (vis USI)

8. PWM on 3 pins (more possible with Software PWM)

9. ADC on 4 pins

10. Power LED and Test/Status LED (on Pin0)

2* USB ATTINY85 Boards

2* Male Pin Headers

2* Female Sockets
