Raspberry Pi Pico (RP2040

A high-performance, low-cost microcontroller board built on the custom-designed RP2040 silicon.

The Raspberry Pi Pico brings professional-grade silicon to the maker market with the RP2040 chip: a dual-core Arm Cortex-M0+ running at 133MHz. It packs 264KB of internal RAM and supports up to 16MB of off-chip Flash (2MB included on-board) to handle complex embedded logic. Beyond standard UART, SPI, and I2C controllers, the standout feature is the Programmable I/O (PIO) subsystem. These eight state machines allow you to create custom hardware interfaces (like VGA or SD card protocols) without taxing the main processors. Whether you are coding in C++ or MicroPython, the Pico provides a stable, flexible platform for everything from industrial sensor arrays to handheld gaming consoles.
