Picture of Chipper Board - ATtiny Programming Shield
Unleash the full power of an Arduino in 10 different kinds of ATtiny chips.

The Chipper Shield allows anyone with an Arduino or AVR programmer to easily program ATtiny chips. ATtiny chips are the core behind many projects that only need a few pins and cost a fraction of an Arduino ($1-4). With access to PWM and Analog pins ATtiny chips can take on any project in 8, 14 and 20 pin form factors.

Want your own version of the board? The Kickstarter is live!

Features of this shield include:
  • 100% Arduino compatible
  • Program ATtiny 85/45/25/15/13  84/44/24  2313/4313 chips.
  • Debug your program with 2 LEDs and a broken out sensor port.
  • Compatible with either an Arduino board or AVR programmer
  • House sensors on the proto area of the board with access to broken out power and ground.
  • Reset a chip mid-program with the reset button.

Step 1: History

Picture of History
When I first learned about ATtiny chips, I was ecstatic because there were a number of projects that I worked on where an Arduino was simply to big for the project/expensive. 

First working with ATtiny chips proved to be frustrating however. It was a real hassle to wire the chip up in a breadboard program it, insert it into the project, realize something was wrong in the code and start all over again. Debugging was only agitated by the lack of indicators and inability to reset the chip.

What I needed was a way to debug the ATtiny chip without constantly prying it out of DIP sockets (poor legs). Thats when it hit me: AN ATTINY PROGRAMMING SHIELD!

The board is actually on its 3rd version.

Is it possible to program other chips or are the ATtiny the only ones compatible with the arduino programing?

The ATtiny chips are the only ones compatible with my board. With the right board definition though I don't see why you couldn't program any other type of AVR chip.

Thats a really well done board! It look professional :)

Nicely done. I thought about doing individual sockets for my ATtiny / ATmega programmer shield (the ArduinoISP Deluxe Shield), but I felt one ZIF socket was a better way to go. I hate prying chips out of those sockets.
