Flux Copilot is the first of its kind AI assistant for hardware. It lives inside Flux and acts as an expert teammate or a senior electronics engineer available 24/7 to debug. It helps you feel like you're working with a larger team, helping you move faster, smarter, and more creatively.

We’ve been so amazed with the ways you’ve used Copilot to brainstorm, debug, and conduct part research that we’ve compiled some of our favorite prompts you can copy and paste, or modify for your own use!

What is a Copilot prompt?

Copilot prompts are natural language inputs given to a custom-trained large language model (LLM) specifically designed to understand the principles and methodology of electronics engineering, circuit design, schematic design and PCB design.

For example, if the prompt is

"How would I connect ILI9341 and SPI TFT LCD?"

the model will generate an answer in a human-like manner based on the prompt. And because Copilot lives inside the PCB design tool, not only it provides direct feedback, advice, analysis, and with your approval - it can take action, through a simple chat interface. With just press of a button, Copilot can connect components together.

The future of hardware design is already here with Flux Copilot, offering a new and faster way for hardware engineers to work, making it more fun as well. Learn more about Flux Copilot.
