Raspberry Breadstick
by Breadstick Innovations
Raspberry Breadstick is a long, lean, delicious development board with a unique form factor that simplifies your journey into the world of electronics. Whether your goal is to build a robot or an interactive art piece, you’ll begin by prototyping with a microcontroller development-board and a breadboard. Doing this with traditional dev-boards quickly leads to a tangled mess of jumper wires. The Raspberry Breadstick spreads its I/O pins out along the length of the breadboard, eliminating the need for long jumper wires, and delivers a clean prototyping experience that is easier to understand and troubleshoot.
The Raspberry Breadstick eliminates the need for lengthy jumper wires through a classroom-friendly design, while still catering to experienced hobbyists and engineers.
Code with Ease in Python
The Raspberry Breadstick fully supports CircuitPython and MicroPython, offering a hassle-free coding experience. Embrace Python’s beginner-friendly syntax, a skill relevant across diverse industries. Why struggle with complex coding languages when you can save time and accelerate your projects with Python? Raspberry Breadstick’s also compatible with Arduino programming language for those that prefer that flavour.
Explore Exciting Features
The Raspberry Breadstick is loaded with exciting components to help ensure your exploration is both educational and enjoyable. Control 24 vibrant RGB LEDs effortlessly using the Adafruit DotStar library or FastLED library. Gather rotation & accelerometer data from the 6-axis IMU, opening the door to captivating LED POV displays that react to your every move as you wave your breadstick through the air!
Maximize Pin Utility
Designed for your convenience, the Raspberry Breadstick’s strategic pin spacing ensures efficient use of every available pin, keeping your component layout clean and organized. Unlike traditional development boards that need long jumper wires to connect every component, our design maintains a clean and organized workspace.

CircuitPython 9.1.0-beta.1
This is the latest development release of CircuitPython that will work with the Raspberry Breadstick.
Alpha development releases are early releases. They are unfinished, are likely to have bugs, and the features they provide may change. Beta releases may have some bugs and unfinished features, but should be suitable for many uses. A Release Candidate (rc) release is considered done and will become the next stable release, assuming no further issues are found.
Please try alpha, beta, and rc releases if you are able. Your testing is invaluable: it helps us uncover and find issues quickly.

Absolute Newest
Every time we commit new code to CircuitPython we automatically build binaries for each board and language. The binaries are stored on Amazon S3, organized by board, and then by language. These releases are even newer than the development release listed above. Try them if you want the absolute latest and are feeling daring or want to see if a problem has been fixed.
Previous Versions of CircuitPython
All previous releases of CircuitPython are available for download from Amazon S3 through the button below. For very old releases, look in the OLD/ folder for each board. Release notes for each release are available at GitHub button below.
Older releases are useful for testing if you something appears to be broken in a newer release but used to work, or if you have older code that depends on features only available in an older release. Otherwise we recommend using the latest stable release.
