About this project
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.
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.
This contains all of the parts needed to assemble your Chipper shield. Basic soldering is required. See the assembly guide here.
The exact same as the Chipper Kit, except that I solder all of the parts together for you and ship you the finished product.
This contains one each of the ATtiny 85,84,2313.
After the project ends (assuming it is successful!) I will contact you about creating a personalized Chipper Kit. This could include different silkscreen text, support for different ATtiny chips of your choice and any other ideas that you would like incorporated into your board. And of course plenty of ATtiny chips to support your projects.
How do I assemble and use the board?
I have put together a series of guides on how to use and assemble the Chipper shield:
Where, Why, and How did this project originate?
Ever since I first learned to use an Arduino, it became a staple in my electronics projects. Unfortunately, though, a number of those projects only needed a fraction of the pins so an entire Arduino was overkill, not to mention an added expense to each project.
When I learned about Atmel's line of ATtiny chips I was ecstatic. Finally a chip with far fewer pins that could stand entirely alone at a fraction of the cost!
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! I built a shield in Cadsoft Eagle and sent it of to my favorite fab house OSHpark where the boards that you will receive are coming from.
3 versions later the board came to fruition containing all of the functionality that I was looking for at a low cost and tiny size for a tiny chip.
Where can I see more photo and projects that involve the Chipper shield and ATtiny chips?
Please take a moment to visit the chipper website.
When can I see the Eagle files that this board is built on?
The moment that this project is successfully funded I will release the files on the Chipper website. Here is a preview of what the board file looks like:
When will I receive my reward?
I will begin shipping as soon as possible, so the kits will arrive in mid-July, but I will try and get them out sooner if possible. International shipping will likely be closer to the end of July.
Will my reward be tracked in the mail?
I will email you to let you know when your reward ships. All Domestic and International mail will be tracked with USPS First Class mail.
Risks and challenges
The board definitions that make this compatible with the Arduino IDE are the product of some fantastic work by the people behind the arduino-tiny core project.
I would be cautious about using other board definitions on the internet as I had limited success getting some of them to work.Learn about accountability on Kickstarter
