The Raspberry Pi Pico is a breakthrough low-cost microcontroller built around the RP2040 — Raspberry Pi's own silicon. It features a dual-core Arm Cortex-M0+ running at up to 133 MHz, 264 KB SRAM, and 2 MB of flash. Programmable in C/C++ using the official SDK or in MicroPython. The Pico brings industrial-grade performance, temperature sensor, DMA, and programmable I/O state machines (PIO) — a unique hardware feature that lets you bit-bang fast protocols without CPU overhead. Ideal for robotics, real-time data, and hobby projects that need more headroom than Arduino.
