• RP2040: Acts as the central processing unit and can manage all external peripherals.
• Power Supply: Provides power to the RP2040 and other components.
• Oscillator: Provides the clock signal needed for the RP2040 to operate.
• SWD (Single Wire Debug): Used for programming and debugging the microcontroller.
• USB Interface: Facilitates communication and power supply via USB.
• ADC (Analog-to-Digital Converters): Collects analog inputs.
• GPIO (General Purpose Input/Output): Manages digital input and output operations.
• LCD Display: Optionally connected to the RP2040 for visual output.
