Understanding J1 Connector
Please explain what J1 does.

General
Project
J1
J1 is the project's USB micro connector. It serves as the physical interface for USB connectivity, meaning it:
- Provides a connection point for USB cables: Allowing data communication and power delivery between your circuit and external devices (e.g., computers or peripherals).
- Handles the standard USB signals: Such as the power supply (VBUS), ground (GND), and data lines (D+ and D-).
- Ensures adherence to USB specifications: By connecting the system to the universally accepted USB protocol, which covers cable design, signal integrity, and power requirements.
In essence, J1 enables your circuit to interface with other USB-enabled devices for both communication and power purposes.

Missing Footprints
Reports parts that have no footprint.
Invalid Layer
Reports nodes that are assigned to a layer that doesn't exist in the layout stackup.
Component Overrides
Reports components that have been modified using the "!important" flag.
Airwires
Reports terminals that are not connected properly. NOTE: Only connections to the center of pads are considered valid.
Deprecated Rules
Reports nodes that are using rules that are not supported anymore.
Layers with Multiple Fills
Reports layers that have multiple copper fills of different nets. Make sure the Connected Layers rule value of nets with fills is valid.
Floating Copper
Detect any via, trace or copper fill island that is not connected to any net.
