Raspberry Pi Pico is a low-cost, high-performance microcontroller board with flexible digital interfaces. It incorporates Raspberry Pi's own RP2040 microcontroller chip, with dual-core Arm Cortex M0+ processor running up to 133 MHz, embedded 264KB of SRAM and 2MB of on-board Flash memory, as well as 26x multi-function GPIO pins.

For software development, either Raspberry Pi's C/C++ SDK, or the MicroPython is available. There're also complete development resources and tutorials to help you get started easily, and integrate it into end products quickly.
