The microcontroller market — the place chips designed for real-time embedded use are positioned into growth boards sometimes known as “microcontrollers” themselves — isn’t shaken up. In order for you one thing pleasant to novices, you choose an Arduino with a Microchip ATmega328; if you would like connectivity, an Espressif ESP32-based board; for efficiency, STMicro’s STM32 collection.
The Raspberry Pi Pico, a $4 growth board with a strong, customized dual-core Arm Cortex-M0+ microcontroller and versatile programmable enter/ output (PIO) blocks, shook issues up with its launch this yr — nevertheless it was the information that these new RP2040 chips can be bought individually at simply $1 every that induced the largest aftershocks.
Accompanying the Pico’s launch, quite a lot of producers launched boards based mostly on the RP2040: Adafruit, Arduino, Pimoroni, and SparkFun to begin. Within the months since, almost 70 bulletins have adopted with designs spanning the gamut from domain-specific devices just like the Raspberry Fish synth from TINRS to general-purpose tinkering boards like Invector Labs’ Challenger RP2040.
“We’re fairly proud of how issues are going,” Raspberry Pi co-founder Eben Upton instructed us. “A lot of enthusiasm for the neighborhood as folks actually begin to perceive what the chip can do. We’re nonetheless on observe to clear our Pico backlog, and get RP2040 into high- quantity, over 1 million unit availability earlier than the top of the yr.”
Adafruit’s Limor Fried amplifies the joy, saying “It’s probably the greatest issues to ever occur for electronics.”
At time of writing, we’ve recognized over 60 distinct boards that make the most of this new chip, with extra coming repeatedly.

We discovered extra RP2040 boards on Twitter:
Blinking LEDs on my DIY RP2040 board. Soldering the chip was a bit difficult, and I couldn’t use the defaults of the sdk so I needed to make my very own board definitions, however I bought all of it to work. pic.twitter.com/8qbhlO2bPN— Pim de Groot (@mifune) June 26, 2021

Engaged on one more RP2040 design. This time to check out some 1.54″ E-Ink shows we picked up a couple of months in the past. That is the Inky Tree 2040 🙂 It isn’t performed, in all probability will add some buttons and STEMMA/QWIIC connectors and some different GPIO headers. pic.twitter.com/fJqG2hPzDN— 🎃 Spoo(a)ok Dev Tech 🎃 (@oakdevtech) August 16, 2021
