1. VIN Connections:
   • Power Source: Connect the power supply positive terminal (let's assume net VCC) to $U1:VIN$.
   • Input Capacitor: Connect $C8:P2$, $C9:P2$, and $R4:P1$ to $U1:VIN$. Ensure $C8:P1$ and $C9:P1$ are connected to GND.
2. GND Connections:
   • Connect $U1:GND$ to GND (connect both GND pins).
   • Ensure the GND net includes capacitor grounds $C8:P1$ and $C9:P1$.
3. VOUT Connections:
   • Connect $U1:VOUT$ to the output load (assuming net VOUT).
   • Add appropriate output capacitors if required (e.g., connect $C11:P1$ to VOUT and $C11:P2$ to GND if specified).
4. EN (Enable) Pin:
   • Connect $U1:EN$ to $R4:P2$ and source it from the controlling signal (e.g., net EN).
5. ADJ (Adjust) Pin:
   • Typically, if you're using an adjust pin for setting the output voltage, you'll have a voltage divider. Since no resistors are explicitly defined for this, we'll assume default operation or N.C. (unless specified otherwise).

• Connect $U1:VIN$ to $R4:P1$, $C8:P2$, $C9:P2$.
• Connect $U1:GND$ to GND.
• Connect $U1:VOUT$ to VOUT.
• Connect $U1:EN$ to $R4:P2$.

1. Right-click on the Pin: Right-click on the pin that you want to mark as no connection.
2. Select "No Connect": From the context menu, select the option to mark the pin as a "No Connect".
3. Verify: Ensure that the pin is now marked with the no connection symbol, which indicates that it should not be wired to anything.

1. Right-click on Canvas: Right-click anywhere on the canvas.
2. Select Copilot: Choose the Copilot option for a design review.
3. Review: Take the default prompt, edit it if necessary, and ask Copilot for a design review. This step acts as a sanity check and can also catch unintentional connections or missing components[1].

1. Add a No Connect Symbol:
   • You can create a text label or a symbol to indicate "NC" (No Connection) near the unconnected pin.
   • In the properties section, make a note that this pin is not to be connected.
2. Use a Visual Marking:
   • You can draw a small line segment near the pin without connecting it to anything.
   • Import a footprint or symbol that denotes no connection and place it adjacent to the pin.

1. Place a No Connection Text Label:
   • Right-click on the blank area of the canvas and select "Insert Comment" (or press C).
   • Type in "NC" and position the comment near the pin to indicate it’s intentionally left unconnected.

1. Drag and Drop Method:
   • Drag a component until one or more of its pins are on top of the pins from another component, then drop it. The overlapping pins will instantly become connected.
2. Drawing Wires:
   • Draw a wire over multiple pins. Draw your wire in such a way that it overlaps multiple pins, then finish drawing. All of the pins will now be connected to the wire.

1. Using Drag-and-Drop:
   • Click and drag $SPK1$, align its input pin with the output pin of $U1$, then release.
2. Using Wire Drawing:
   • Click to start drawing a wire from $U1:OUT$.

1. Leave a comment asking Copilot to wire up specific components or connections.
2. Use the "Take Action" button if available to have Copilot perform the connections for you. This is especially useful when you have detailed connection requests like wiring up an SPI bus[3].

• Lightning Speed Connections: Some methods and tools within Flux are designed to make connections more intuitive and faster[4].
• Connection Suggestions: You can ask specific questions about component connections directly in your comments. For example, "@copilot how do I connect the flash memory to the RP2040?" to get guided and automatic connections[5].

1. Name Assignment:
   • Generally, the name of the power net should indicate the voltage level and type. For instance, you might name a 5V power net as "VCC" or "VDD", and the ground net as "GND".
2. Voltage Value:
   • For power nets that represent a specific voltage, you need to specify the voltage value. This can be done by associating a net label or net property to the PowerNet object.

1. PowerNet1: Let’s assume this represents a 3.3V power rail.
   • Rename PowerNet1 to "VCC_3V3".
2. PowerNet2: Let’s assume this represents ground (GND).
   • Rename PowerNet2 to "GND".

1. Adding and Renaming Power Ports:
   • In Flux, you can add a power port by selecting the "Add Component" tool and choosing the appropriate power symbol.
   • Rename the added power port in the properties pane or directly in the schematic.
2. Connecting Power Nets in Flux:
   • Connect the PowerNet1 port to all components requiring 3.3V.
     • Rename PowerNet1 to "VCC_3V3".
   • Connect the PowerNet2 port to all points in your circuit that should be connected to ground (GND).
     • Rename PowerNet2 to "GND".

• PowerNet1 (VIN, 3.3V):

  • Ensure it is connected to the following:
    • U1:VIN
    • C9:P2
    • C8:P2
• PowerNet2 (GND):

    • C12:P1
    • C14:P1
    • C15:P1
    • U1:GND
    • R9:P1

• VCC_3V3: Explicitly note this is 3.3V by adding a text label near the net.
• GND: Typically, GND is understood to be 0V, so an additional label is optional.

1. Place a Portal: First, place a portal component from the parts library.
2. Assign Designator: Assign a unique designator to the portal corresponding to your power net (e.g., PWR1, 5V, or any other specific name).
3. Connect Components: Connect your components to the portal using wires or by matching the designator with other portals.

1. Add a Portal to Your Schematic:
   • From the parts library, drag in a portal component. If you're looking for a ground portal, you can search for a portal with a ground symbol $\{\{8a66144c-0122-5dc4-aced-2794c26489a2\}\}$.
2. Assign Designator:
   • Click on the portal and open its properties panel.
   • Enter a designator name that you want for your power net. This could be something like 5V, GND, 3.3V, etc.
3. Connect Using Portals:
   • Add other portals with the same designator name to connect different parts of your circuit to the same power net. Ensure that each portal intended for the same power net has the same designator $\{\{7baec845-287a-5c1f-b595-dcd9e5584f17\}\}$.
4. Highlight Connected Nets (Optional):
   • In Flux, when you click on a net, all instances of the net will be highlighted. This helps verify if connections are correctly linked $\{\{0d7deeec-2167-5c33-8df4-25111792e456\}\}$.

• Portal for 5V: Place a portal and set its designator to 5V.
• Portal for GND: Place another portal and set its designator to GND.

3. Connect Pins Using Net Labels:
   • You can add net labels to the pins to identify the nets they are connected to. This is especially useful for clear documentation and understanding of the circuit.
   • Select the Net Label tool and place it on the wires connecting the pins, then name the labels identically to ensure they are part of the same net.

1. Click on the Global Label tool.
2. Place the global label on the first pin, e.g., $R1:1$.
