The Raspberry Pi Pico is a low-cost, high-performance microcontroller board built around custom silicon (the RP2040 or newer RP2350 chips). Unlike standard Raspberry Pi computers, it does not run an operating system like Linux; instead, it runs individual programs written in MicroPython or C/C++ to control hardware.

Processor: Dual-core ARM Cortex M0+ (or upgraded cores on the Pico 2 series)
I/O Pins: 26 multi-function general-purpose input/output (GPIO) pins
Connectivity: Wireless models (like Pico W and 2W) include 2.4GHz Wi-Fi and Bluetooth 5.2
Programming: Flashed directly via USB using MicroPython or C/C++
