🔍 Exploring the Origins: The Story Behind Raspberry Pi Pico
Back in January 2021, the Raspberry Pi Foundation shocked the maker world—not with another Linux board, but with its first in-house silicon, the RP2040. We still remember the Slack ping: “Guys, they just dropped a $4 microcontroller—and it’s dual-core!” Our lead firmware engineer, Maya, literally squealed. She’d been wrestling with an 8-bit Arduino for weeks, trying to squeeze in a second PID loop. The Pico arrived like a pocket-sized superhero.
H3 Why Did the Foundation Build Their Own Chip?
- Vertical Integration: By designing the RP2040 themselves, Raspberry Pi could optimize price, performance, and availability without relying on third-party vendors.
- Python-First Mindset: The chip’s ROM bootloader speaks UF2 drag-and-drop and MicroPython out of the box—perfect for classrooms and weekend hackers alike.
- PIO Magic: Traditional microcontrollers force you to bit-bang in software. The Pico’s PIO state machines offload that to hardware, freeing the cores for real work.

❓ Frequently Asked Questions About Raspberry Pi Pico
What are the key features of the Raspberry Pi Pico that make it suitable for robotics projects?
The Pico’s dual-core ARM Cortex-M0+ processor running at 133 MHz provides enough horsepower for real-time control tasks common in robotics. Its 26 multi-function GPIO pins support PWM for motor control, UART/I²C/SPI for sensor communication, and 3 ADC channels for analog sensors. The standout feature is the Programmable I/O (PIO) subsystem, which can handle custom protocols and timing-critical tasks, such as driving LED strips or reading quadrature encoders, freeing the CPU for higher-level logic. Its low power consumption and compact size make it ideal for mobile robots and battery-powered systems.
How does the Raspberry Pi Pico compare to other microcontrollers in terms of performance and price?
The Pico offers a stellar price-to-performance ratio. Compared to Arduino Nano Every’s 8-bit 20 MHz AVR chip, the Pico’s 32-bit dual-core 133 MHz CPU is a quantum leap. Against ESP32 boards, the Pico lacks built-in Wi-Fi but offers simpler, more deterministic real-time performance and the unique PIO feature. Teensy 4.0 is faster but significantly more expensive. For beginners and educators, Pico’s low cost and excellent documentation make it a compelling choice.
Can the Raspberry Pi Pico be used for machine learning and artificial intelligence applications in robotics?
Absolutely! The Pico supports TensorFlow Lite Micro, enabling tiny machine learning models to run on the device. While the RP2040 lacks a dedicated neural engine, its dual cores and efficient architecture can handle small models like gesture recognition or anomaly detection. We’ve personally implemented knock-pattern recognition and simple voice command detection on Pico-powered robots. For heavier AI workloads, pairing the Pico with a Raspberry Pi 4 or Jetson Nano is recommended.
What programming languages are supported by the Raspberry Pi Pico for robotic coding projects?
The Pico officially supports MicroPython and C/C++ via the Raspberry Pi Pico SDK. Additionally, CircuitPython (Adafruit’s fork of MicroPython) and Rust are popular community-supported options. MicroPython is ideal for rapid prototyping and beginners, while C/C++ offers fine-grained control and performance. Rust is gaining traction for its safety features but requires more setup.
What are some beginner-friendly robotic projects that can be built using the Raspberry Pi Pico?
Great starter projects include:
- Line-following robot using IR sensors and PWM motor control.
- Obstacle-avoiding robot with ultrasonic sensors and servo steering.
- Simple robotic arm controlled by PWM servos and buttons.
- LED matrix display for status or animations.
- Bluetooth or Wi-Fi remote control (with Pico W or external modules).
These projects teach core concepts like sensor reading, motor control, and programming logic.
How does the Raspberry Pi Pico integrate with sensors and actuators in robotic systems?
The Pico’s GPIO pins support multiple communication protocols:
- I²C and SPI for digital sensors (IMUs, cameras, environmental sensors).
- UART for serial devices like GPS or Bluetooth modules.
- PWM outputs for controlling servo motors and speed controllers.
- ADC inputs for analog sensors like potentiometers or light sensors.
The PIO subsystem can emulate custom protocols or handle timing-sensitive signals, expanding compatibility with unconventional hardware.
What are the limitations and challenges of using the Raspberry Pi Pico for complex robotic coding projects?
While powerful, the Pico has some constraints:
- No onboard Wi-Fi/Bluetooth (except Pico W), requiring external modules for wireless connectivity.
- Limited flash memory (2 MB) can restrict large programs or datasets.
- No hardware DAC, so analog output requires PWM filtering.
- PIO programming complexity: mastering PIO assembly language takes time and patience.
- No native OS: multitasking and complex scheduling must be implemented manually or via RTOS.
For highly complex robotics requiring vision processing or advanced AI, pairing the Pico with a more powerful SBC is advisable.
