Raspberry Pi Pico Schematic in 20 minutes using Flux Copilot

Raspberry Pi Pico Schematic in 20 minutes using Flux Copilot

Imagine designing a PCB in a third less time than you're used to - that's the power of Flux Copilot's new upgrade, allowing it to wire components together for you. In this tutorial, we'll walk you through the important workflows and example prompts to help you design a Raspberry-Pi-Pico-like board in 20 minutes.

To put this new feature to the test, we revisited a recent project where we designed a Raspberry-Pi-Pico-like schematic using only AI. Initially, it took us 30 minutes to complete the design using Flux Copilot's advice. With Copilot taking the lead on making connections, the same schematic design was completed in just 20 minutes!

In this tutorial, we'll walk you through the important workflows and example prompts to help you design a Raspberry-Pi-Pico-like board in 20 minutes. Curious about the end result? Take a look at the finished project here.

Using the New Flux Copilot in Your PCB Design Process

Using generative AI for PCB design means working at the very edge of current possibilities. This requires a few workflow adjustments to get the most out of it. These are some of the principles we found work particularly well, but we can't wait to hear what you come up with. Let us know in Slack!

Your input and interactions play a significant role in getting the most out of Copilot. Be clear and precise with your objectives, don't hesitate to explore different suggestions, and feel free to give feedback with a thumbs up. We compiled a list of useful prompts if you want to learn more about what Copilot can do.

Go from general to specific. It's much easier to get precise responses when Copilot is provided with more details. You can get those details by first asking more broad questions and use Copilot's response to ask a more detailed question. When you're confident about Copilot's reponse, use the "Take action"button to have Copilot wire the schematics for you.

Use Copilot as a teammate. Depending on the question, it might take Copilot a few seconds to reply. Use that time to focus on other areas of the design, Copilot can answer several questions in parallel.

Without further ado, let's dive into the prompts that made this project happen:.

Identify Required Components

At the start of your project, you'll need to identify the necessary components. This is a good opportunity to ask more general questions at first and start narrowing down the scope of the project.

For a Raspberry Pi Pico-like board, your interaction with Copilot might look like this:

@copilot what is the minimum set of components I need to make a Raspberry Pi Pico-like board?

Minimize Datasheet Reading

Having to sift through datasheets consumes a significant amount of time.

When you find a part in the library that you think might for your design, ask Copilot to verify:

@copilot does this LDO work for powering the RP2040?

If you're not familiar with some of the ICs in your design, you can ask Copilot what other components are required or what a pin is used for:

@copilot how should I connect the shield pin?@copilot what else do I need for the oscillator?@copilot what decoupling capacitors do I need for the RP2040?

Have Copilot Take Action

Copilot can do the wiring for you and save you precious time. Before you ask Copilot to take action, make sure you provide it with as much information as you can. If a component can be connected in multiple ways (as a flash memory to the RP2040), state your goals clearly.

@copilot how do I connect this flash memory to the RP2040? I want to make sure I can boot from it.

If you take a close look at the final project, you'll notice that these patterns repeat over and over on the different elements. Once you get familiar with this workflow, you'll be designing at a speed only big teams were able to accomplish in the past.

Towards a More Efficient PCB Design Process

It's an exciting time for PCB design. With this new feature of Flux Copilot, we're not just accelerating the design process but also opening up new possibilities for creativity and innovation. It's like having a skilled coworker by your side, ready to tackle the complex parts so you can focus on the big picture.

We're eager to see what amazing designs you'll create with Flux Copilot. This is just the beginning of a fascinating journey toward a future where AI assists in creating, imagining, and realizing incredible hardware designs. And we're thrilled to be on this journey with you.

Happy designing!

A Flux Birthday Special: A Look Back at Four Years of Flux

A Flux Birthday Special: A Look Back at Four Years of Flux

In 2019, we scratched our heads at the current state of hardware tools. Why did they look like they were designed in the 1980s? Ohhhh they were. We asked ourselves... what if we started from scratch? What if designing hardware was seamless, intuitive, even delightful? What if we could automate all the mundane work? That was our dream.

In 2019, we scratched our heads at the current state of hardware tools. Why did they look like they were designed in the 1980s? Ohhhh they were. 😬

We asked ourselves... what if we started from scratch? What if designing hardware was seamless, intuitive, even delightful? What if we could automate all the mundane work? That was our dream.

Fast forward three years, and boom! We opened up to everyone. Since then, the numbers have been wild. Over 100,000 of you have joined, creating a whopping 177,000 projects! And shout out to the 3,200 businesses riding this wave with us. We've even got PCBs designed in Flux going to space soon! 🚀

Let’s take a look back at some of the company’s major highlights that you helped us fulfill!

Milestone #1: Emerging From Private Beta

From the very beginning, we always knew that Flux was only going to be as successful as the community that we built around it. That’s why we started with a private beta: so that we could build a tight-knit community of people who shared the same vision as us as we grew the product. If it weren’t for that group of beta users in the very beginning, we would not be here with you today.

In February 2023, we took our next big step when we emerged from private beta. For the first time ever, anyone in the world was able to test out Flux, and the response was overwhelming. This was our first major step towards our ultimate goal of truly democratizing hardware design for everyone.

Milestone #2: From World’s First AI PCB Design Assistant to Generative AI

We’ve always sought to take the “hard” out of hardware, and it was obvious that existing tools came up short of that vision. We knew we had to think bigger, which is why we came up with Flux Copilot: the industry’s first and only AI PCB design assistant.

When we introduced Copilot, its capabilities were unprecedented, and the response from YOU was fantastic. Over 15,000 users have now worked with Copilot, and it’s tackled a whopping 130,000 questions.

But we didn't stop there. Copilot evolved to not just provide feedback but to take action for you. With Copilot’s ability to wire up schematics for you, users were finally able to avoid the tedium of wiring schematics and spend more time on what really matters. We want to put the magic back in hardware design, and generative AI with Copilot has been one huge step toward that goal.

Milestone #3: Let's Celebrate With Our Users

Meet Gerald, a software engineer behind Vendo King Manila, a vending machine business in the Philippines. Before Flux, he struggled with jumbled boards and too many jumper wires. With no prior PCB design experience, Gerald dived into Flux and crafted his own board. He says, “With Flux, I made our PCB easily. No more wire mess or production problems!” That's a big win! 🚀

Left: a circuit board with messy wires using a breadboard. Right: Clean printed circuit board with organized connections through PCB traces.

Then there's Robert, a software engineer who loves computers, old-school games, web development, and 3D printing. He's the guy behind ControllerAdapter.com, making cool stuff for game controller fans. Thanks to Flux, Robert easily designs and shares his creations.

and wait a moment for Flux Copilot to response with the calculated total resistance value. It can even determine series or/and parallel resistor configuration automatically. It's like your holding a physical ohm meter and reading the actual resistance of a circuit. See it for yourself!

Understanding Parallel and Series Resistor Configurations

As electronics enthusiasts and professionals, we are always on the lookout for tools that can streamline our design process and improve our understanding of circuit behavior. The parallel and series resistor calculator is one such indispensable tool that enables efficient and accurate analysis of resistor networks. In this comprehensive guide, we will explore the concept of parallel and series resistors, the importance of resistor calculators, and the benefits they provide.

Parallel Resistors

Parallel resistors refer to resistors connected end-to-end, sharing the same voltage across their terminals. When resistors are connected in parallel, their combined resistance is less than the smallest individual resistor's value.

The total resistance in a parallel configuration is given by the formula:

1/R_total = 1/R1 + 1/R2 + ... + 1/Rn

Series Resistors

Series resistors are connected in a way that the end terminal of one resistor is connected to the starting terminal of the next resistor. In series configuration, the current flows sequentially through each resistor, and there is only one current path through the entire resistor network. The resistors should beconnected end-to-end, with no junction points or branches between them. Worth noting that same current flows through each resistor in this configuration, and the voltage drop across each resistor is proportional to its resistance.

The total resistance in a series configuration is simply the sum of the individual resistances:

R_total = R1 + R2 + ... + Rn

The Need for Parallel and Series Resistor Calculators

Manual calculations can be tedious, time-consuming, and error-prone, particularly when dealing with multiple resistors or complex circuits. This is where parallel and series resistor calculators come into play, offering valuable benefits such as:

  • Simplified and accurate calculations

Resistor Color Code Calculator

Resistor Color Code Calculator

Easily calculate resistor values with Flux online Resistor Color Code Calculator. This powerful tool saves time and eliminates errors for electronics enthusiasts and professionals.

How to Identify the Value of a Resistor Using Its Color Code?

Resistors are ubiquitous components in the world of electronics, playing a crucial role in regulating current flow, setting voltage levels, and protecting other components in circuits. As you dive into projects or repairs, it's important to understand how to identify the value of a resistor to ensure proper functionality and avoid potential issues. One of the most common methods to determine a resistor's value is by interpreting its color code. In this article, we will guide you through the process of identifying the value of a resistor using its color code, helping you become proficient at reading these codes and ensuring the success of your electronic endeavors.

What value are resistors measured in?

Resistors are measured in ohms (Ω), the unit of electrical resistance. The ohm represents how much a resistor opposes or resists the flow of electric current in a circuit. Resistance values can range from a fraction of an ohm (e.g., milliohms or mΩ) to many millions of ohms (e.g., megaohms or MΩ). When selecting a resistor for a particular application, it's important to choose one with the appropriate resistance value to achieve the desired effect in the circuit.

What is resistor color code?

The color code for resistors is a universal method employed to signify a resistor's resistance value, tolerance, and its temperature coefficient for 6-band resistor. This system features a sequence of color bands printed on the resistor's surface, simplifying the identification of the resistance value without requiring extra markings or tags.

The color code system employs 10 colors, each assigned a numerical value:

| Band Color | Value | | :=== | :=== | | Black | 0 | | Brown | 1 | | Red | 2 | | Orange | 3 | | Yellow | 4 | | Green | 5 | | Blue | 6 | | Violet | 7 | | Gray | 8 | | White | 9 |

Resistors typically have 4, 5, or 6 colored bands:

  • A 4-band resistor has two value bands, one multiplier band, and one tolerance band.
  • A 5-band resistor adds a third value band to the 4-band configuration.
  • A 6-band resistor includes a third value band and an additional band for the temperature coefficient.

You can determine the resistor's resistance value, tolerance, and temperature coefficient by reading the colored bands and referring to the color code chart. This system makes it simple and efficient to identify and select resistors for various electronic applications.

Understanding the Resistor Color Code

To read the resistor color code effectively, it's essential to understand how the bands represent different attributes of a resistor. Let's dive deeper into the significance of each band and how to interpret them:

  1. First and Second Value Bands (for 4-Band) or First, Second, and Third Value Bands (for 5-Band and 6-Band): These bands represent the significant digits of the resistor's value. For example, if the first two bands on a 4-band resistor are brown and black, the significant digits would be 1 and 0 (based on the color chart). For 5-band or 6-band resistor, an additional value band provides greater precision.
  2. Multiplier Band: The multiplier band denotes the factor by which the significant digits should be multiplied. For instance, if the multiplier band is orange, the multiplier would be 1,000 (10^3). So, for a resistor with red and violet as the first two bands and orange as the multiplier band, the resistance value would be 27 x 1,000 = 27,000Ω.
  3. Tolerance Band: This band indicates the acceptable variation in the resistor's resistance value, expressed as a percentage. A gold band represents a 5% tolerance, while a silver band signifies a 10% tolerance. If a resistor has no tolerance band, it implies a 20% tolerance. The tolerance helps users understand the possible deviation of the resistor's actual value from the nominal value.
  4. Temperature Coefficient Band (6-Band only): This additional band, found only on 6-band resistors, represents the temperature coefficient, which indicates how the resistance changes with temperature. It is expressed in parts per million per degree Celsius (ppm/°C). A common temperature coefficient band color is brown, representing 100 ppm/°C.

Practice and Tips for Reading Resistor Color Codes

Becoming proficient at reading resistor color codes requires practice. Here are some tips to help you along the way:

  • Ensure proper lighting conditions to accurately distinguish between similar colors such as blue and violet or green and brown.
  • Keep a resistor color code chart or mnemonic handy for quick reference until you are comfortable with the color-to-number associations.
  • You need to identify the correct starting point for reading the bands. The tolerance band is usually gold or silver and should be positioned to the farthest right. In some cases, you may find that the resistor body has a slightly flattened side, which can also help determine the correct orientation.

By familiarizing yourself with the resistor color code system and practicing reading the bands, you'll be well-equipped to identify resistor values and select the appropriate components for your electronic projects.
