The Raspberry Pi Pico is a low-cost, high-performance microcontroller board built around the RP2040 chip — a dual-core Arm Cortex-M0+ processor running up to 133 MHz, with 264KB RAM and 2MB of onboard flash. With 26 multi-function GPIO pins (including 3 analog inputs), it's perfect for embedded projects, robotics, and physical computing. Programmable in C/C++ or MicroPython.
