Raspberry Pi Pico

The Raspberry Pi Pico is Raspberry Pi's first microcontroller board, built around the custom-designed RP2040 chip. This compact, low-cost development platform brings the flexibility and ease-of-use of the Raspberry Pi ecosystem to microcontroller projects.

With a dual-core ARM Cortex-M0+ processor running at up to 133MHz, 264KB of SRAM, and 2MB of onboard flash, the Pico delivers impressive performance for its price. The unique Programmable I/O (PIO) subsystem enables custom peripherals and high-speed interfaces not possible with standard microcontrollers.
