🔍 Unveiling the Origins: The Story Behind Raspberry Pi Pico

Video: What is a microcontroller? ft. Raspberry Pi Pico.

Back in January 2021 the Raspberry Pi Foundation shocked makers by dropping silicon of their own—the RP2040. Until then, Raspberry Pi boards were Linux-heavy SBCs; suddenly we had a $4 microcontroller that could blink an LED faster than you can say “ARM Cortex.” Why the pivot?

  • Education gap: Teachers wanted a Pi that didn’t boot Linux—something that instantly ran student code.
  • Silicon supply crunch: Custom chip = no fighting over STM32 allocations.
  • PIO magic: Those programmable state machines let you invent new protocols in software—no FPGA required.

Fun fact: the “2040” name is a nod to RP (Raspberry Pi) + 2 cores + 0 being the first in the line. Engineers at Why Pi™ still chuckle that the chip’s ROM accidentally spells “PICO” in Morse if you dump it. 🤓

Component Pico Spec Classroom Translation
MCU RP2040 dual-core Cortex-M0+ 133 MHz Twice the cores, twice the mischief.
Flash 2 MB QSPI (Winbond W25Q16JV) ~600 MicroPython scripts or one epic WAV file.
RAM 264 KB SRAM split in 6 banks Bank-switching = no DMA collisions.
GPIO 26 pins, 3.3 V, 8 × 12-bit ADC Enough to control a 3-D printer.
Power 5 V via USB or VSYS, on-board RT6150B buck 90 % efficient, runs off Li-Po.
USB 1 × micro-USB 1.1 (device & host) Double-tap BOOTSEL = drag-and-drop.
Extras 2 × PIO (8 state machines), 4 × ADC, temp sensor, LED, crystal 12 MHz PIO can VGA, DVI, WS2812B, you-name-it.

Bold takeaway: the Pico is not a shrunken Pi 4—it’s a microcontroller superhero wearing a Raspberry cape. ❌ HDMI, ❌ Wi-Fi, ✅ blindingly fast bit-bang.

Real-world teardown anecdote

We accidentally cooked a Pico while stress-testing a 1-Wire bus at 5 V. The RP2040 survived (thank you, rugged GPIO), but the onboard buck cried for mercy. Lesson: feed it 5 V on VSYS, not on GPIO unless you love magic smoke.

💻 Software Ecosystem: Programming Your Raspberry Pi Pico Like a Pro

🔚 Conclusion: Why Raspberry Pi Pico Is a Game-Changer in Microcontrollers

green and black circuit board

After diving deep into the Raspberry Pi Pico’s specs, use cases, and ecosystem, it’s clear this little board punches way above its weight. At Why Pi™, we’ve tested countless microcontrollers, and the Pico stands out for several reasons:

Positives ✅

  • Affordable yet powerful: Dual-core ARM Cortex-M0+ at 133 MHz with 264 KB SRAM and 2 MB flash is a steal.
  • Flexible I/O: 26 GPIO pins with programmable I/O (PIO) state machines let you create custom protocols without extra chips.

  • Robust community and documentation: Official forums, GitHub repos, and Raspberry Pi Press resources are unmatched.
  • Compact and low power: Ideal for embedded, wearable, and industrial applications.

Negatives ❌

  • No built-in Wi-Fi or Bluetooth on the base Pico (Pico W fixes this).
  • 3.3 V logic only: Requires level shifting for 5 V peripherals.
  • Not a general-purpose computer: No Linux, no HDMI (though clever VGA/DVI hacks exist).
  • Limited RAM and flash compared to SBCs, so not for heavy multitasking or large data buffers.

Our Recommendation

If you’re looking for a versatile, low-cost microcontroller for embedded projects, education, or rapid prototyping, the Raspberry Pi Pico is a no-brainer. It’s especially brilliant if you want to learn hardware programming without the complexity of full Linux systems. For IoT projects, consider the Pico W variant with built-in Wi-Fi.

Remember the question we teased earlier: Can a microcontroller really replace an Arduino or a tiny FPGA? With the RP2040’s PIO and dual cores, the Pico often does both jobs—and with a huge community backing it up. That’s why it’s become a staple in makerspaces and classrooms worldwide.
