As an experienced tinkerer, I‘ve gotten familiar with both the Raspberry Pi Pico and Arduino platforms over years of building electronics projects. If you‘re trying to pick between the two popular microcontrollers, let me help break it down so you can make the best choice.
We‘ll dive into:
- Background on Raspberry Pi and Arduino
- Detailed spec comparison
- Programming environments
- Pros and cons of each option
- Recommendations based on your experience level and project needs
Let‘s get started!
A Brief History
First, a quick background on Raspberry Pi and Arduino before looking at their latest products.
The Evolution of Raspberry Pi
Raspberry Pi emerged from a nonprofit founded in 2009 by Eben Upton and colleagues at the University of Cambridge. Their goal was to create an affordable computer to make programming more accessible for kids learning to code.
After releasing several iterations of Raspberry Pi single-board computers (SBCs) throughout the 2010s, they launched their first microcontroller in 2021 – the Raspberry Pi Pico.
Let‘s look at what makes this new board unique.
Arduino Through the Years
Arduino got its start back in 2005 from a team of developers in Italy seeking to provide an easy way for non-engineers to start tinkering with electronics.
Co-founders Massimo Banzi and David Cuartielles designed the original Arduino board for students without deep technical skills or equipment to build prototypes.
Along the way, iconic boards like the Arduino Uno brought microcontrollers to the maker community worldwide.
Now in 2023, Arduino boards power all kinds of hobbyist electronics and IoT products thanks to beginner-friendly hardware & software with tons of community support.
Side-By-Side Spec Comparison
Here is an overview of the key capabilities of both the Raspberry Pi Pico and popular Arduino Uno Rev 3:
(insert image comparing Pi Pico and Arduino Uno sizes)
| Spec | Raspberry Pi Pico | Arduino Uno Rev 3 |
|---|---|---|
| Dimensions | 51mm × 21mm × 3.0mm | 53.4mm × 68.6mm |
| Processor | RP2040 (Cortex M0+) Dual Core @ 133Mhz | ATmega328P @ 16Mhz |
| Flash Memory | 2MB | 32 KB |
| RAM | 264KB (133Mhz) | 2KB |
| GPIO Pins | 26 | 14 (digital) |
| ADC Pins | 3 channels, 12-bit | 6 channels, 10-bit |
| Networking | None | None |
| Default Programming Language | MicroPython (can use C/C++) | C++ (Arduino) |
| USB | USB 1.1 | USB 2.0 Type B |
| Starting Price | $4 | $23 |

Based on the specs above, here are some key differentiators:
-
The Pi Pico provides substantially better performance thanks to its dual-core 133Mhz ARM processor – nearly 10X faster than the Arduino Uno‘s 16Mhz ATmega328P. This gives it an edge for complex calculations.
-
Arduino offers superior ease-of-use for coding, especially for total beginners. Its simplified IDE helps you flash an LED in under 10 minutes without needing much hardware knowledge upfront.
-
In terms of sheer connectivity, the Pi Pico wins with over 2X as many GPIO pins for hooking up sensors, motors and displays.
Keep those differences in mind as we explore further!
Programming Environments
One of the biggest considerations when selecting a development board is coding environment and languages supported.
Here is how Raspberry Pi Pico and Arduino compare:
Coding the Pi Pico
As you may know, most Raspberry Pi products utilize Python as the go-to programming option, thanks to its simplicity for beginners.
Following in those footsteps, MicroPython is the stock language loaded on all Pi Pico boards. Experienced Python devs will recognize the familiar syntax.
For resource constrained applications, the Pi Foundation also provides a full C/C++ SDK offering low level control of the dual core processor. This unlocks superior performance for number crunching algorithms.
So in summary, developers can utilize:
- Beginner-friendly MicroPython out of the box
- Performant C/C++ for direct hardware access when needed
Programming Arduino
One major value-add of Arduino is the integrated, open-source Arduino IDE for flashing code onto boards.
Rather than worrying about complex compiler toolchains, the graphical interface lets you drag-and-drop functions to blink LEDs or react to sensor inputs in minutes. This abstraction means beginners can get building projects right away.
Under the hood, Arduino utilizes the Wiring framework which is itself based on C and C++. So you get the wide software compatibility and speed associated with those languages, while hidingimplementation details behind the scene.
For makers who have some coding experience already, you can always drop down to writing C/C++ natively for direct hardware manipulation or performance gains.
Pros and Cons Comparison
To help summarize key advantages of the Raspberry Pi Pico and Arduino boards, here is a high-level pros & cons breakdown:
Raspberry Pi Pico Pros
- Very affordable starting at only $4
- More powerful dual-core processor
- Tons of GPIO pins to connect sensors and displays
- Castellated pads for easy DIY soldering
- Flexible enough for MicroPython or low-level C/C++
Pi Pico Cons
- Lacks display/networking onboard like other Pi products
- Not as beginner friendly as Arduino
Arduino Uno Pros
- Massive software libraries & tutorials available
- Beginner-oriented programming environment to learn fast
- Huge ecosystem of stackable shields for new functions
- Ridiculously easy to prototype circuits with plug-and-play pins
Arduino Cons
- Single-core 16Mhz CPU limits complex workloads
- Lacks native high-speed interfaces like USB and Ethernet
As with most tech decisions, there are good-fitting applications for both. To help illustrate, here are example projects where I would favor the Pi Pico or Arduino Uno:
Pi Pico Good For:
- Computer vision applications reading multiple camera feeds
- Running neural network inferencing models at the edge
- Controlling complex robotics with precise servo signals
- Implementing home automation hub collecting sensor data
Arduino Shines When:
- Hooking up simple environmental monitors with basic triggers
- Building student kits to learn coding fundamentals
- Creating rapid-prototype contraptions like milk jugs that moo when squeezed
- Constructing interactive LEGO sculptures responding to touch
Hopefully those specific examples help provide some intuition where each platform excels based on strengths.
Recommendations By User Experience Level
Given the pros, cons and target applications covered above, here is my suggested guidance on which platform to evaluate first depending on your background:
Complete Beginners
For makers who have truly no experience with hardware or coding, I would nudge you towards Arduino first. With their simplified IDE and vast learning content available, it‘s easy to pick up those critical fundamental concepts quickly. This will prep you to graduate to more advanced boards like Raspberry Pi Pico down the road.
DIY Enthusiasts With Some Experience
For hobbyists who have already built a few basic circuits or followed some tutorials online, the Pi Pico offers a nice blend of beginner accessibility through MicroPython plus advanced performance when you‘re ready for it. You‘ll also appreciate the huge array of sensors and add-ons that play nicely within the Raspberry Pi ecosystem once you want to level up.
University Students & Engineers
Given the processing punch and professional-level development environment provided by the Raspberry Pi Pico, I generally recommend it for any undergraduate through PhD students looking to build applications around embedded systems and electronics. With support for CircuitPython, MicroPython and C/C++ out of the box, it will grow along with your expertise through the years of study ahead.
IoT Developers & Tech Startups
For tech founders and engineers building connected devices for consumers or industry, I would point you to Pi Pico for prototyping and the clear upgrade path to Raspberry Pi CM4 modules for production. Leveraging open standards like WiFi, Bluetooth, cameras etc – integrating Pi with cloud platforms is straightforward for companies with existing software investments.
Let me know if you have any other questions! I‘m happy to provide buying suggestions for your particular application.
To wrap up, while both Raspberry Pi Pico and Arduino boards have specific applications where they shine, the Pi Pico strikes a great balance of simplicity for beginners plus advanced configurability for experts. For less than $5 it‘s worth trying out regardless of your skill level!
