<br />
== Technical overview ==<br />
* Standard Pico header supports Raspberry Pi Pico series boards.<br />
* 3.5-inch resistive touch screen, 65K colors, 480 × 320 resolution, SPI interface.<br />
* LCD control chip: ILI9488; display size 73.44 × 48.96 mm, IPS panel, pixel size 0.153 × 0.153 mm.<br />
* ICM20948: 16-bit resolution for accelerometer (±2/±4/±8/±16 g), gyroscope (±250/±500/±1000/±2000 °/s), and magnetometer (±4900 µT).<br />
* Micro SD card slot via SDIO interface – faster than SPI.<br />
* Standard 3.5 mm headphone jack for audio peripherals.<br />
* Integrated battery header and recharge circuit allow operation without a wired power supply.<br />
* Additional onboard resources: buzzer, photoresistor, RGB LED (WS2818).<br />
* Supported development environments: MicroPython (Thonny), C/C++ (VS Code + pico-vscode), Arduino IDE.<br />

== Notes and version constraints ==<br />
* The source contains no explicit commands other than the CMake line above; additional commands must be taken from the tutorials.<br />
* Flashing Pico2 firmware using the official MicroPython firmware may cause the device to go unrecognized – use the firmware provided in the package instead.<br />
* CMake files must not contain Chinese characters (including in comments), otherwise project import may fail.<br />
* For RP2040/RP2350: press BOOT and RESET simultaneously, release RESET first then BOOT, so the USB mass storage appears.<br />
* The exact version of the VS Code extension package is 0.15.2; updating to newer versions is possible but not specified in the source.<br />
