The Raspberry Pi Pico is a microcontroller development board designed for low-level embedded control and digital interfacing. It is based on the RP2040 dual-core ARM Cortex-M0+ microcontroller, the first in-house microcontroller developed by Raspberry Pi. The board integrates essential external components including flash memory, crystal oscillator, power regulation, decoupling, and USB connectivity. Most RP2040 GPIO pins are routed directly to the board edges, with a small number reserved for onboard functions such as LED control and power monitoring. It supports flexible power input using an onboard buck-boost SMPS generating 3.3 V from input voltages between 1.8 V and 5.5 V. Suitable for embedded systems development, hardware prototyping, and educational applications.
