== Notes and version constraints ==<br />
* When the RGB LED matrix is fully on (current approx. 350 mA), use a power adapter rated at least 500 mA<br />
* Do not touch the RGB LED beads while the matrix is fully illuminated<br />
* Keeping the RGB LED matrix fully lit for extended periods causes heat buildup, reducing LED lifespan or causing burnout<br />
* Flashing Pico2 firmware from MicroPython may cause the device to become unrecognized; use the firmware provided in the package instead<br />
* When using the VS Code extension package, the .pico-sdk environment must be correctly configured, otherwise compilation will fail<br />
* CMake files must not contain Chinese characters (including comments), otherwise project import may fail<br />
