Product Overview
Raspberry Pi Pico is a microcomputer designed by the Raspberry Pi Foundation in the UK, based on the RP2040 microcontroller. It features a dual-core Arm Cortex-M0+ processor with a high frequency of 133MHz and flexible clock settings. The Pico is equipped with SRAM and QSPI flash, providing storage capabilities. Additionally, it has 26 multifunctional GPIO pins and multiple controllers, suitable for various peripheral connections and control applications. The Pico also supports low-power sleep and deep-sleep modes, along with precise on-chip clocks and a temperature sensor. In summary, the Raspberry Pi Pico is a comprehensive, user-friendly, and easily programmable microcontroller suitable for embedded systems and IoT applications.

Usage
Download Thonny IDE
If you are a beginner, it is recommended to download Thonny IDE for experimenting with the development board. Thonny IDE official website: https://thonny.org/ (Download the appropriate version as needed)
Configure Interpreter and Port
After installation, it is necessary to configure the language and board environment. Since we are using the Raspberry Pi Pico, we select the board environment as Raspberry Pi Pico.
Click on Tools - Preferences, as shown in the figure below, choose the interpreter as MicroPython (Raspberry Pi Pico) in the interpreter field, and set the port (COMx: the port number x may vary on different computers), then click OK.
