BuildWithFlux
Starting a new hardware project can be overwhelming, but the completely overhauled Copilot simplifies the process by guiding you through component selection, spec verification. Just describe your goals and Copilot engages in a focused conversation to refine your requirements like a seasoned hardware engineer.
Ask me a structured set of questions (about 5 one at a time) to help brainstorm and outline the most important parts of a project including the critical technical requirements, including power, components, performance, constraints, Use case etc
Always provide multiple options where applicable, considering trade-offs in cost, efficiency, size, and performance. By the end of this process, I want:
1. A block diagram illustrating the system architecture.
2. A complete list of all components, including passives and active components.
Instead of wading through datasheets and Google searches, use Copilot to select appropriate parts for implementation, recommending main and alternative components that meet design requirements. Tip: You can use tool like @library to direct Copilot to search the part library, or @file to direct Copilot to use datasheet details in it’s responses.
@library List out 5 switching regulators that I can use for my project with a maximum output current of 2A. Include key parameters such as input voltage range, output voltage range, switching frequency, efficiency, and package type.
@file extract the following details from the datasheet of @U2
1. Key features
2. Functional Pin Description
- List each pin with its name, function, and relevant electrical characteristics.
3. From the Typical Application Circuit:
- List all components present along with their values in a table format.
- Describe explicitly how each pin is connected.
4. Any circuit-Specific Design Notes
Identify alternative components for @U4 with similar functionality, pin configurations, and electrical characteristics. Include key differences and trade-offs.
@file extract the absolute maximum ratings of @U1 including voltage, current, and thermal limits. Present the data in a clear table format.
@file Explain @U1 in detail, including its purpose, key functions, and common applications. Describe how it operates within a circuit and any notable characteristics. Also, explain the family or series this component belongs to, highlighting its variations, key differences, and typical use cases compared to other models in the series.
@file Extract the recommended operating conditions for @IC2. Retrieve key parameters such as supply voltage range, operating temperature range, input/output voltage levels, and other relevant conditions specified for optimal performance.
Compare LMR33630ADDAR and MP2451DJ-LF-Z in terms of efficiency, output ripple, load regulation, and thermal performance. Highlight key differences in topology, switching frequency, and suitability for a [specific application, e.g., battery-powered wearable]. Provide a recommendation based on [input voltage range, output voltage, current requirements.
Analyze all the parts in the project context and generate a consolidated parts table that optimizes component selection. Specifically, apply the following consolidation rule:
- Identify passive components (resistors, capacitors, inductors) with the same values but different MPNs (Manufacturer Part Numbers).
- Propose a single standardized MPN for each unique value, prioritizing parts with better availability, and popular supplier.
Present the table clearly. The table must strictly list and analyze all passive components in the project context. It must not use vague terms such as “etc.” or truncate the list in any way. The table should have the following headers (Original Part Category (e.g., Resistor, Capacitor, Inductor), Original Values/Specs (e.g., 10kΩ, 1μF, 100mH), Original MPNs (List all variants found in the project), Proposed Consolidated MPN (Recommended single part), Reason for Consolidation (e.g., same specs, better tolerance, reduced part diversity)
Copilot isn’t just here to answer questions—it can take direct action in your project, helping you place components, modify properties, and refine your design faster than ever. Instead of manually searching for parts or tweaking values one by one, you can ask Copilot to handle specific tasks, like adding a resistor with a defined value or updating a component’s footprint.
When Copilot detects an action it can execute, you’ll see an action button appear—click it to apply the change instantly. If you don’t see a button, try rephrasing your request or breaking it into smaller steps. While Copilot can’t yet generate an entire schematic at once, it’s great at guiding you through the process, handling tedious tasks, and keeping your workflow smooth.
I want the 555 timer to operate at a frequency of 1.5 kHz.
@library add the following components to the project:
- NE555 Timer IC
- 2-Pin Terminal Block Connector (for power input)
- Resistors:
- R1 = 10kΩ
- R2 = 100Ω
- R3 (Current-limiting resistor for output)
- Capacitors:
- C1 = 100nF (0.1µF)

- Diode: 1N4148
- LED
- Ground connection
@library add the following components to this project; NE555 Timer IC, 2-Pin Terminal Block Connector (for power input) and two 0603 1k ohm resistors
When working on a design, precise calculations are key—but instead of crunching numbers manually, Copilot can help streamline the process. Whether you need to size a resistor, calculate power consumption, or verify signal integrity, you can use Copilot to gather equations and relevant data before running calculations.
Start by pulling in the necessary formulas and values using @file or @library, ensuring you have all the details upfront. Once you’ve gathered the required inputs, use the @calculator tool to perform the calculations accurately. Taking this structured approach will help you get the most reliable results from Copilot.
@file obtain the equation for sizing the inductor for @U2, along with the required parameter values needed for the calculation.
@calculator calculate the inductor size for U2 needed for my project (Vin = 5V, Vout = 3.3V, Iout = 1A)
@calculator calculate the required PCB trace width for the 12V power rail according to the IPC-2221 standard. The trace should handle a current of 3A with a maximum allowable temperature rise of 10°C. Assume a copper thickness of 1oz and an ambient temperature of 25°C.

Flux Copilot is already the most powerful chat-based AI design assistant for PCB design, but what if we told you it just got even smarter?
Code Interpreter is the newest tool in Copilot’s arsenal. With access to a built-in Python code interpreter, Flux Copilot can now generate and run Python scripts directly in conversation with you. That means that you can automate workflows, analyze data on the fly, and create custom visualizations without leaving the chat interface.
The result? Your team can solve problems more effectively, work faster, and reduce the risk of errors.
To work with Code Interpreter, simply ask Copilot to perform an analytical task or solve a problem and, in some instances, specify that you’d like it to use Python in the process.
First, Copilot will meticulously describe the steps it takes and its line of reasoning in solving the problem. Then, it will generate a comprehensive Python script for you accordingly, including everything from library imports to function definitions. Finally, Copilot will use its new Code Interpreter powers to execute the script, exporting the results in whatever format you specify.
With Code Interpreter, Copilot can provide tables, plots, and charts that help you better organize, visualize, and understand your project.
Need some examples of the ways that Code Interpreter is a game-changer for Copilot? Check out some of the most compelling use cases we’ve evaluated so far.
EEs often have to refer to datasheets in the design process to figure out device performance specifications, tolerances and ratings.
For example, when choosing current-limiting resistors, like in LED circuits, it's important to design for a specific current flow and power consumption and then size the resistors accordingly based on information in their datasheets. With Code Interpreter, Copilot can use Python to do this analysis for you and then compare your design to the expected results. For example, if a resistor is undersized for an expected power, Copilot can flag this and help you find a better component for your design.
Check out this example in action here.
Sometimes, EEs refer to datasheets to extract equations to guide their design efforts, like in the case of regulator designs.
The process of voltage regulator design requires designers to appropriately size the peripheral components for a given output voltage and current. These values are often based on equations given by the component manufacturer in the datasheet. Instead of manually calculating the needed component values, you can use Copilot’s Code Interpreter to do it for you. Looking at your programmable regulator IC, the design information in its datasheet, and the context of your circuit and project requirements, Copilot creates a Python script that calculates what passive components such as inductor, input and output capacitors and resistor values are ideal. You’ll even get multiple options to pick from, so you maintain freedom in your design choices.
Check out this example in action here.
Relatively complex mathematical equations govern the behavior of analog filters. Instead of calculating poles and zeros to graph a transfer function manually, ask Copilot to do it for you. Copilot can use Code Interpreter to analyze your circuit, calculate the frequency response, and plot your transfer function. You then have access to a detailed plot to review and Copilot-created design feedback and recommendations based on the results.
Check out this example in action here.
Determining your system’s overall power consumption can be tedious and arduous. Done manually, the process entails calculating each component’s power consumption and then adding these up individually to estimate the total system value.
With Code Interpreter, Copilot does it all for you. Copilot can analyze your circuit to understand each component’s power consumption, reading through datasheets where necessary to get reliable figures for active components. Then, it can determine your system’s total power consumption and create charts to help you visualize the major contributors to your system’s power draw.
