Picture of the item

We are looking at purchasing a bunch of digisparks, a very small arduino-a-like with usb

Pledge leader: amx109

The item

We set out to build a little brother to the wonderful Arduino line of development boards - we were tired of leaving our valuable Arduino's behind in projects, or worse, ripping apart old projects to build new ones! We also felt the Arduino was too big and powerful for many projects where we only needed a few pins, or an SPI or I2C bus. And so the Digispark was born! To us, the best things about the Arduino is the community, the easy of use, and the IDE - by making the Digispark an Arduino compatible development board all of those remain common. Plug it in, power your project with USB or external sources, program it with the Arduino IDE, and easily use existing Arduino code! But 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!

Specification

  • 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)

Budget estimation

  • 100USD plus 10USD for shipping for 12 digisparks
    • using xe.com thats 89.22 euros - im rounding it up to 90EUR
    • 7.5 EUR per digispark

Pledges

Running total: €75

Approximate target: €90


The more we get the cheaper they become. 18 may be feasible.
