Innovative MagSafe Breadboard Transforms iPhone into Prototyping Tool

A new device called the Commi Board is set to redefine how users approach circuit prototyping by leveraging an existing smartphone, specifically the iPhone. Designed by Kevin Yang, this MagSafe-compatible breadboard provides a unique interface for electronic experimentation without the need for a separate microcontroller or battery. By utilizing General Purpose Input/Output (GPIO) communication, the Commi Board enables smartphones to manage processing tasks, capitalizing on their superior power and connectivity.

The dimensions of the Commi Board are compact, measuring 62mm by 98mm when mounted and 62mm by 82mm when detached. It boasts a striking color scheme reminiscent of the Flipper Zero, yet it serves a distinct purpose. Unlike the multifunctional Flipper device, which targets various security applications, the Commi Board focuses solely on circuit prototyping and code validation. Its modular design separates the breadboard surface from the MagSafe mounting frame, which is engineered with a circular cutout to accommodate the iPhone’s camera.

Connection options include USB-C 3.2, Bluetooth, and Bluetooth Low Energy (BLE). Yang has incorporated cloud storage functionality, allowing users to initiate projects on their phones and return to them later without the hassle of local file management. Although the project commenced in June 2024, Yang has already developed a working prototype with tested connectivity, indicating significant progress for a student project.

The Commi Board addresses a common challenge in Internet of Things (IoT) hardware design: the tendency to be overly complex. Many devices attempt to integrate numerous features, often resulting in subpar performance. Yang’s innovative approach is to use the smartphone’s existing capabilities, such as its processing power and display, to facilitate a more efficient prototyping experience. This strategy not only reduces weight and manufacturing costs but also eliminates concerns regarding battery degradation over time.

One notable feature of the Commi Board is its modular design, which allows users to attach or detach the board as needed. This flexibility is essential for various testing scenarios, ensuring that users can work comfortably without obstructing the camera or requiring additional space for their circuits.

The device offers four distinct programming methods, catering to a wide range of experience levels. Beginners can benefit from an AI-assisted code generation feature, allowing them to input simple commands like “make an LED blink every second.” More experienced users can utilize a full Integrated Development Environment (IDE) for advanced programming tasks. The transition between these methods is seamless, enabling users to retain their projects regardless of their level of expertise.

Yang asserts that GPIO communication can effectively simulate most microcontrollers, particularly for applications comparable to the Arduino Mega. Despite this, challenges may arise under demanding conditions due to the nature of smartphone operating systems, which can introduce latency. The device’s specifications indicate that while USB-C can handle more intensive tasks, Bluetooth is suitable for casual control.

Cloud storage enhances the user experience by allowing for secure project management. This feature is crucial for maintaining momentum in prototyping, as it prevents the loss of ideas and progress due to forgotten details or time constraints. The potential for community collaboration is also on the horizon, with Yang hinting at the possibility of opening an API for third-party development. This could transform the Commi Board from a standalone product into a broader platform, unlocking new opportunities for innovation.

With a working prototype already demonstrating core functionality, the future looks promising for the Commi Board. Should Yang choose to pursue crowdfunding or startup avenues, the device may well find its place in the growing landscape of electronic prototyping tools. The combination of practicality, innovation, and user-centric design positions the Commi Board as a significant advancement for both beginners and seasoned engineers alike.
