How do I rename this component?

@copilot How do I rename this component?

copilot

To rename a component in Flux.ai, you typically need to change its "Designator". The designator is the label (e.g., U1, R2, C3) used to uniquely identify a component in your schematic. Here's how you can do it:

Click on the component you wish to rename in your schematic to select it.
Look for the property panel on the right side of the screen. If it’s not visible, make sure the component is selected, or try clicking on it again.
Within the property panel, find the "Designator" field. It should display the current designator of the selected component.
Click on the text box with the current designator, then type in the new name you wish to assign to the component.
Press "Enter" or click anywhere outside the text box to finalize the change.

Keep in mind the naming conventions for designators to maintain clarity in your schematic:

Use "R" for resistors (e.g., R1, R2).
Use "C" for capacitors (e.g., C1, C2).
Use "U" for integrated circuits (e.g., U1, U2).
Use "J" for connectors (e.g., J1, J2).
Use "SW" for switches (e.g., SW1, SW2).

If you are referring to changing another property of the component (like the MPN or the Manufacturer Name), you would follow a similar process but update the respective field in the property panel instead.

Please specify if you meant renaming a different aspect or if you encounter any issues while renaming a component!

@copilot list all J1 pins in a table format. For each pin provide its pin number, pin name and function.

copilot

Here's a table listing all the pins for the component J1 (MPN: PJ-202A) along with their pin number, pin name, and assumed function. Since the datasheet excerpts for the PJ-202A are not available and functions are not directly provided, I'll infer the functions based on common configurations for such connectors.

Table

Pin Number	Pin Name	Assumed Function
1	1	Signal
2	2	Ground (GND)
3	3	Signal or Power Supply

Please note, the specific function (especially for pins 1 and 3) can vary depending on your application and the specifics of how the PJ-202A is implemented in other designs. The functions listed here are assumptions and should be verified for your specific use case.
