Notes and version constraints

• Version-specific: The FPC connector was updated from V1.1 onward; identify version by the "Rev*. *" marking on the back
• Do not unplug while powered – risk of short circuit when removing the cable
• Flashing firmware: Hold BOOT button, connect board, then copy the firmware file to the appearing drive
• VS Code: CMake files must not contain Chinese characters, otherwise project import may fail
• Pico2 firmware from the Micropython package can cause recognition issues; use the recommended firmware files
