• RP2040 Microcontroller represents the central microcontroller on the Raspberry Pi Pico.
• Power System includes the various power inputs and supplies.
• UART GPIO0 GPIO1, GPIOs GPIO2 to GPIO13, GPIOs GPIO14 to GPIO22, ADC GPIO26_ADC0, GPIO27_ADC1, GPIO28_ADC2, ADC_VREF, and Debug SWDIO, SWCLK represent the specific GPIO and ADC pins defined in your project.
• Ground Connections consolidates all GND pins in the schematic.

1. Search for the Raspberry Pi Pico footprint
   • In the Flux component library, seek for 'Raspberry Pi Pico' or 'Pico' related components. If there's a similar component, you can use that.
   • If none exists, you will need to create a new component.
2. Create a New Component (if necessary)
   • In the left panel, click on 'Components', and click the 'Create Component' button.
   • Set the parameters for the component:
     • Name: Raspberry Pi Pico
     • Description: Raspberry Pi Pico microcontroller
   • Then proceed to define the pins according to the Raspberry Pi Pico pinout.
3. Define the Pins
   • You need to add 3 groups of pins according to the Raspberry Pi Pico datasheet:
     • Ground pins (GND)
     • Power pin (3V3)
     • GPIO pins (GPIO0 to GPIO29, including specific roles for some GPIOs such as ADCs, RUN, SWDIO, SWCLK...)
4. Configure the Footprint
   • After defining the pins, you need to configure the layout for the footprint. You can do this in the Footprint Editor available in Flux.
   • Create a rectangle of size 21x51mm (size of the Raspberry Pi Pico) and place the pins accordingly. Recall, it's a dual row header with a distance of 17.78mm (700mil) between rows. Each pin should have a distance of 2.54mm (100mil) to the adjacent pins.
5. Save and Use Your Component
   • After setting up the footprint, click 'Save'. You can now find your created component in your custom component library.
