Microcontroller Boards Raspberry Breadstick Crowdfunding Project

Raspberry Breadstick is a uniquely designed development board that is long and tidy. Whether you are looking to build anything, you can start prototyping using microcontroller development boards and breadboards. When using traditional development boards, the issue of messy jumper wires often arises. With Raspberry Breadstick, this problem can be largely avoided as the I/O pins stretch along the length of the breadboard, eliminating the need for long jumper wires. This provides a clean prototyping experience, allowing users to understand and troubleshoot more conveniently.

Even without the need for messy jumper wires, Raspberry Breadstick can still be a valuable companion for experienced enthusiasts and engineers.

Code with Ease in Python

Raspberry Breadstick supports CircuitPython and MicroPython, offering a comfortable coding experience. The use of Python, with its beginner-friendly syntax, meets the diverse needs of users across various industries. Furthermore, Breadstick is also compatible with the Arduino programming language.

Explore Novel Features

Raspberry Breadstick comes loaded with many exciting components to ensure your exploration experience is filled with fun. For instance, control 24 vibrant RGB LEDs using the Adafruit DotStar library or the FastLED library. Gather rotation and accelerometer data from the 6-axis IMU, and then open up LED POV, where the display reacts to every move as you swing the breadstick in the air!

Maximize Pin Utility

The design philosophy behind Raspberry Breadstick is all about convenience, and its strategic pin spacing ensures the efficient utilization of every available pin. This helps maintain a tidy and organized layout of components, providing a well-structured workspace without the need for long jumper wires to connect each component.
