🕰️ The Rise of Microcontrollers: A Brief History of Arduino and the Raspberry Pi Pico’s Genesis

a pomegranate sitting on top of a reflective surface

Picture it: the mid-2000s. Getting into electronics was… tricky. You needed deep knowledge, expensive tools, and the patience of a saint. Then, in 2005, a little blue board from Italy changed everything. The Arduino was born, and it was revolutionary! It made microcontrollers accessible to students, artists, and hobbyists, sparking the modern maker movement. For years, if you wanted to blink an LED or read a sensor, Arduino was the undisputed champion of the DIY Electronics world.

For over a decade, Arduino reigned supreme. We at Why Pi™ have built countless projects with them, and their simplicity is legendary. As one of our favorite YouTubers mentioned in their excellent video breakdown, “If it can’t talk to an Arduino, then it can’t talk to anything.”

But the tech world never stands still. The Raspberry Pi Foundation, already famous for its single-board computers, saw an opportunity. They noticed a gap for a microcontroller that was not only cheap but also powerful and flexible. In January 2021, they dropped a bombshell: the Raspberry Pi Pico. It wasn’t a computer; it was a microcontroller, and it was aimed squarely at the world Arduino had built. But this wasn’t just a clone; it was a complete reimagining of what a tiny, affordable board could do. This article will explore that, but if you want to see how it stacks up against another major player, check out our deep dive: Raspberry Pi Pico vs Arduino vs ESP32: Which Microcontroller Reigns Supreme? 2024.

So, did this newcomer actually dethrone the king? Let’s find out.

🧠 The Brains Behind the Boards: Processor Power & Architecture

Video: WHICH IS BETTER? Raspberry Pi Pico vs Arduino Nano.

At the heart of every microcontroller is its processor, the “brain” that does all the thinking. Comparing the Pico and the classic Arduino Uno here is like comparing a modern sports car to a beloved vintage pickup truck. Both will get you there, but one is built for speed and performance.

Why Pi™ Rating: Processor & Memory

Feature Raspberry Pi Pico Arduino Uno R3 Why Pi™ Verdict
Processor Speed 9/10 4/10 The Pico’s dual-core ARM chip is leagues ahead.
Architecture 9/10 5/10 A 32-bit architecture offers far more flexibility than 8-bit.
RAM 10/10 3/10 It’s not even a close race; the Pico has vastly more memory.
Flash Storage 9/10 4/10 More space for bigger, more complex projects on the Pico.
Overall 9.3/10 4.0/10 For raw computational power, the Pico is the clear winner.

1. CPU & Clock Speed: Who’s the Speed Demon?

  • ✅ Raspberry Pi Pico: Inside the Pico is the RP2040, a custom-designed chip from the Raspberry Pi team. It features a dual-core 32-bit Arm Cortex-M0+ processor that can run up to 133 MHz. Two cores mean it can literally do two things at once, which is a massive advantage for complex tasks.
  • ❌ Arduino Uno R3: The Uno uses an 8-bit single-core ATmega328P chip, which chugs along at a steady 16 MHz. It’s reliable and gets the job done for simple tasks, but it’s old technology.

The difference is staggering. The Pico isn’t just a little faster; it’s an entirely different class of performance. As Elecrow notes, the RP2040 is so impressive that other manufacturers, including Arduino themselves, are now using it in their own boards!

2. Memory Matters: RAM & Flash Storage Showdown

If the CPU is the brain, then RAM is its short-term memory, or its workspace.

  • ✅ Raspberry Pi Pico: It comes with a generous 264KB of SRAM. This is a huge workspace that allows you to handle large amounts of data, run complex algorithms, and create sophisticated applications.
  • ❌ Arduino Uno R3: The Uno is equipped with a mere 2KB of SRAM. This is a tiny amount by modern standards. We’ve all been there: you’re building a project, add one too many libraries, and boom—you’ve run out of memory. It’s a common frustration in the Arduino world.

For permanent storage of your code (Flash memory), the story is similar: the Pico has 2MB of onboard Flash, while the Uno has just 32KB. More space means more features, more libraries, and more possibilities.

🔌 Connecting the Dots: GPIO & Peripheral Powerhouses

Video: Arduino vs Raspberry Pi Pico vs ESP32: Which Microcontroller Should You Choose? (2025 Comparison).

A microcontroller is useless if it can’t talk to the outside world. That’s where the General-Purpose Input/Output (GPIO) pins come in. This is where you connect LEDs, motors, sensors, and all the other fun components in our Electronic Component Reviews.

Why Pi™ Rating: I/O and Connectivity

Feature Raspberry Pi Pico Arduino Uno R3 Why Pi™ Verdict
GPIO Pins 9/10 7/10 The Pico offers more multi-functional GPIO pins.
Analog Inputs 7/10 8/10 The Uno has more analog pins, but the Pico’s are higher resolution.
Communication 9/10 6/10 More hardware I2C, SPI, and UART controllers on the Pico.
Unique Features 10/10 5/10 The Pico’s PIO is a revolutionary feature with no Arduino equivalent.
Overall 8.8/10 6.5/10 The Pico’s flexibility and unique PIO give it a powerful edge.

3. Digital & Analog Pins: The Basic Building Blocks

Here’s a quick comparison of the I/O capabilities:

Specification Raspberry Pi Pico Arduino Uno R3 Key Difference
Total GPIO 26 20 (14 digital, 6 analog) Pico has more multi-purpose pins.
Operating Voltage 3.3V 5V Crucial! Using 5V devices with Pico can damage it without a level shifter.
Analog Inputs 3 (up to 4) 6 Uno has more dedicated analog pins.
ADC Resolution 12-bit (4096 steps) 10-bit (1024 steps) Pico offers more precise analog readings.
PWM Pins 16 channels 6 channels More options for controlling things like motor speed or LED brightness on the Pico.

While the Arduino Uno has more analog input pins, the Pico’s are higher resolution, giving you more precise measurements. The most important difference, however, is the logic level voltage. The Pico runs at 3.3V while the Uno runs at 5V. This is not a small detail! One of our junior engineers learned this the hard way when he fried a Pico by connecting a 5V sensor directly. Always use a logic level converter when mixing 3.3V and 5V devices!

4. Communication Protocols: I2C, SPI, UART & Beyond

For talking to more complex sensors and devices, you’ll use standard communication protocols. The Pico comes out ahead here, with more dedicated hardware controllers:

  • Raspberry Pi Pico: 2x I2C, 2x SPI, 2x UART controllers
  • Arduino Uno: 1x I2C, 1x SPI, 1x UART controller

This means the Pico can manage more complex projects with multiple sophisticated components without relying on software workarounds that slow down the processor.

5. Unique Features: PIO on Pico vs. Arduino’s Simplicity

This is where the Raspberry Pi Pico truly leaves the competition in the dust. It has a feature called Programmable I/O (PIO). PIO is like having eight extra, tiny processors on your chip that you can program to handle high-speed I/O tasks.

What can you do with PIO?

  • Create custom communication protocols: Need to talk to a weird, old piece of hardware? PIO can do it.
  • Drive lots of NeoPixels: PIO can manage the precise timing needed for addressable LEDs without bogging down the main processor. Tom’s Hardware calls the Pico’s GPIO a “Swiss Army knife” largely because of this feature.
  • Output video or audio: Yes, people have made the tiny Pico generate VGA video signals and digital audio, tasks that are simply impossible on an Arduino Uno.

Arduino’s strength is its simplicity. What you see is what you get. The Pico, with PIO, has a hidden depth that allows for incredibly advanced applications, making it a favorite in our lab for pushing the boundaries of what’s possible.

💻 Speaking Their Language: Programming & Development Experience

How you write code and get it onto the board is a huge part of the experience. Both platforms have their strengths, but the Pico offers a more modern and flexible workflow, especially for newcomers.

Why Pi™ Rating: Coding & Ease of Use

Feature Raspberry Pi Pico Arduino Uno R3 Why Pi™ Verdict
Language Options 10/10 7/10 MicroPython is a game-changer for beginners and rapid prototyping.
Beginner IDE 9/10 8/10 Thonny is fantastic, and the classic Arduino IDE is very user-friendly.
Advanced Tools 9/10 7/10 Pico’s C/C++ SDK and debug support are top-notch.
Flashing Code 10/10 8/10 The Pico’s drag-and-drop UF2 bootloader is foolproof.
Overall 9.5/10 7.5/10 The Pico offers a superior experience for both beginners and experts.

6. Coding Languages: C++, MicroPython, and Beyond

  • ✅ Arduino: The standard is the Arduino Language, which is essentially a set of C++ functions that make it easy to control the hardware. It’s powerful and has been the foundation of maker Microcontroller Programming for years.
  • ✅ Raspberry Pi Pico: The Pico offers you a choice:
    1. C/C++: For maximum performance and low-level control, you can use the official C/C++ SDK. This is for power users who want to squeeze every ounce of performance out of the hardware.
    2. MicroPython: This is the Pico’s killer app. MicroPython is a version of the popular Python language optimized for microcontrollers. It’s incredibly easy to learn, read, and write. Tom’s Hardware rightly says, “The path of least resistance is via MicroPython.” You can write code and see results in seconds.
    3. CircuitPython: A fork of MicroPython from Adafruit with excellent library support for their wide range of sensors and components.

For us, MicroPython is the reason the Pico is often a better choice for learning. A beginner can get an LED blinking in MicroPython in about three lines of code, with no complex setup.

7. IDEs & Toolchains: Your Digital Workbench

  • Arduino: The classic Arduino IDE is simple and gets the job done. It bundles the editor, compiler, and uploader in one place. While it’s a bit dated, it’s reliable and easy for beginners to grasp.
  • Raspberry Pi Pico:
    • For MicroPython, the recommended IDE is Thonny. It’s a fantastic, lightweight Python editor with built-in support for the Pico. You just plug in your board, and it works. You can write code and run it instantly without a separate compile/upload step.
    • For C/C++, the setup is more advanced, typically involving setting up a toolchain in Visual Studio Code. It’s more powerful but has a steeper learning curve.

A huge win for the Pico is its UF2 bootloader. To upload new code in C/C++, you simply hold down the ‘BOOTSEL’ button while plugging it in, and it appears on your computer like a USB drive. You just drag and drop the file. It’s simple and can’t be “bricked.”

8. Libraries & Ecosystem: A Wealth of Resources

This is one area where Arduino’s long history gives it an advantage.

  • ❌ Arduino: The ecosystem is massive. There are libraries and tutorials for almost any sensor or component you can imagine. The number of third-party “shields” (add-on boards) is enormous, allowing for easy, solder-free expansion.
  • ✅ Raspberry Pi Pico: The ecosystem is newer but is part of the wider Raspberry Pi world, which means it has excellent official documentation. The number of third-party “hats” and libraries is growing exponentially. Because the RP2040 chip is so popular, support is coming from all corners of the community, including from major players like Adafruit and SparkFun.

While you might find a pre-written Arduino library for an obscure old sensor that doesn’t exist for Pico yet, this is becoming rarer every day. For most common components, the Pico is very well-supported.

💰 The Practicalities: Cost, Power, and Physical Form

Video: Raspberry Pi vs Arduino vs Pi Pico vs ESP32. Whats the difference???

Let’s talk about the real-world factors that influence your choice: how much it costs, how it sips power, and what it looks like.

Why Pi™ Rating: Physical & Financial

Feature Raspberry Pi Pico Arduino Uno R3 Why Pi™ Verdict
Cost 10/10 5/10 The Pico’s value is nearly unbeatable in the electronics world.
Power Consumption 8/10 8/10 It’s a tie; each has advantages depending on the use case.
Form Factor 9/10 7/10 Pico’s compact, solder-friendly design is more versatile.
Overall 9.0/10 6.7/10 The Pico’s incredible price and modern design make it a winner.

9. Price Point Punch-Up: Value for Your Venture

This is the easiest comparison to make.

  • ✅ Raspberry Pi Pico: The official price is incredibly low. The affordability of this board is one of its most compelling features.
  • ❌ Arduino Uno R3: An official Arduino Uno is significantly more expensive. While cheaper clones exist, their quality can be questionable.

For the price of one official Uno, you could buy a handful of Picos. This makes the Pico an amazing choice for education, for projects where you might damage a board, or for applications where you need to deploy many devices. As NextPCB states, “If you factor price with processing power, it’s the Raspberry Pi Pico, hands down.”

10. Power Consumption: Battery Life & Efficiency

This is a nuanced topic. In a head-to-head test by Tom’s Hardware driving a strip of NeoPixels, the Arduino Uno actually consumed less power (1.5W) than the Pico (3.1W). This is likely due to the Uno’s simpler, slower processor.

However, that’s not the whole story. The Raspberry Pi Pico has highly configurable low-power “sleep” modes that the Uno lacks. You can put the Pico’s cores to sleep and wake them up with a timer or an external trigger, allowing it to run for a very long time on a battery. Elecrow notes its sleeping power consumption is less than half that of the Uno.

Verdict: For simple, continuously-running tasks, the Uno might be slightly more efficient. For battery-powered projects that need to wake up periodically, the Pico’s advanced power management is superior.

11. Form Factor & Pinout: Size, Solder, and Shields

  • Arduino Uno: It’s a larger board with pre-soldered female headers. This makes it great for beginners, as you can just plug in jumper wires and go. The pins are clearly labeled on the board.
  • Raspberry Pi Pico: It’s a much smaller, more compact board. It typically comes without headers, requiring you to solder them on yourself. However, it features castellated edges, which are half-holes on the side of the board. This brilliant design allows you to solder the Pico directly onto a custom circuit board like a stamp, which is fantastic for creating professional, permanent projects.

The Uno is easier to start with out of the box, but the Pico’s form factor is ultimately more versatile for both breadboarding (with soldered pins) and creating final products.

🎯 Who’s It For? Target Audience & Learning Curve

Video: The Arduino has met it’s match -Raspberry Pi Pico.

So, who should pick which board? It’s not just about the specs; it’s about the experience.

12. Beginner-Friendly vs. Advanced Tinkering

For years, the answer to “what should a beginner buy?” was always “an Arduino.” It’s still a fantastic choice. The hardware is simple, and the IDE is straightforward.

However, we at Why Pi™ now argue that the Raspberry Pi Pico with MicroPython is the new best way to start. The Thonny IDE is incredibly intuitive, and the Python language is more forgiving and readable than C++. The instant feedback of an interactive REPL (Read-Eval-Print Loop) makes learning and debugging a joy.

For advanced users, the Pico is also the clear winner. The dual-core processor, massive RAM, and especially the game-changing PIO feature open up a world of possibilities that are simply out of reach for an 8-bit Arduino.

13. Community & Support

  • Arduino: Has a massive, mature community. If you have a problem, chances are someone has solved it in a forum post from 2011. The sheer volume of existing projects, libraries, and tutorials is a huge asset.
  • Raspberry Pi Pico: The community is younger but incredibly vibrant and growing fast. The key advantage here is the official support from the Raspberry Pi Foundation. Their documentation is second to none—clear, comprehensive, and professionally written. You won’t have to rely on outdated forum posts to figure things out.

So, after all this technical talk, where would you actually use one over the other? Let’s get practical.

14. Arduino’s Domain: Robust & Reliable Automation

The Arduino Uno is still a fantastic choice for projects where its vast ecosystem of shields and libraries provides a shortcut.

  • Simple Robotics: Controlling a simple robotic arm or a small rover where tons of pre-existing code can be leveraged.
  • Home Automation: Reading a temperature sensor and turning on a fan. The 5V logic can also be more convenient for controlling common relays.
  • Interactive Art Installations: When you just need to read a few buttons and blink some lights, the Arduino is a quick and easy solution.
  • Learning C++: It remains an excellent, focused platform for learning the fundamentals of C++ in an embedded context.

15. Raspberry Pi Pico’s Playground: High-Speed & Custom Peripherals

The Raspberry Pi Pico excels where you need more power, more memory, or more flexibility. If your project idea makes an Arduino sweat, it’s probably perfect for a Pico.

  • Digital Signal Processing: Analyzing audio or other sensor data in real-time. The dual-core processor and large RAM are perfect for this.
  • Custom LED Controllers: Driving large numbers of NeoPixels or other addressable LEDs smoothly using PIO.
  • Multi-Sensor Data Loggers: Reading from multiple I2C or SPI sensors simultaneously and logging the data to an SD card.
  • Emulating Old Peripherals: Using PIO to create a controller for a vintage keyboard or joystick.
  • Machine Learning: Yes, you can run tiny machine learning models (TinyML) on the Pico for things like voice recognition or gesture sensing, a task far beyond the Uno’s capabilities. This is a hot topic in the Electronics Industry News.
