Raspberry Pi Pico is a $4 Arduino alternative

The microcontroller is even built on in-house silicon.

Raspberry Pi Foundation

The Raspberry Pi Foundation has so far focused its energy on microcomputers, but it’s now turning its attention to Arduino-style microcontrollers for your homebrew gadgets. The organization has introduced the Raspberry Pi Pico, a $4 board meant to offer a gentle entry point for microcontrollers. Think of it more as a complement to a Pi aimed at tasks like analog input.

It’s built on Raspberry Pi’s own in-house silicon, the RP2040. The dual-core ARM Cortex-M0+ chip, 264KB of RAM and support for 16MB of off-flash memory (2MB is onboard) may not sound like much, but they’re reportedly powerful for the class with strong performance for tasks like machine learning. More importantly, it’s built to be flexible — the 30 GPIO pins, USB 1.1 controller (plus USB mass storage mode) and other additions should help it interface with with whatever project you’re working on.

The RP2040 is also part of a broader ecosystem. Adafruit, Pimoroni, SparkFun and even the Arduino team have developed boards tailored to more specific needs. One of Pimoroni’s devices may be the most interesting — the PicoSystem is a £58.50 (about $80) “handheld game-making experience” that has you programming a console even smaller than the Game Boy Micro.

Raspberry Pi Pico will be available in North America through Newark starting on January 25th. The RP2040 should be “broadly available” to customers sometime in the second quarter of 2021. This won’t necessarily up-end the Arduino market, but it won’t have to — it’s an alternative that could help you finish DIY creations and teach you a thing or two about code and hardware development.
