I2C_SDA near a microcontroller and another portal named I2C_SDA near a sensor represent the same SDA signal net. This makes the schematic easier to read while maintaining the actual electrical connection in the netlist.P1, with pin type unspecified. There are no nets defined in the part project itself; the portal gains its practical meaning when instances are placed into another schematic and assigned matching designators.3V3, 5V, VBAT, or GND-like domain labels.RESET, ENABLE, INT, SCL, SDA, MOSI, MISO, TX, or RX.Table
| Symbol type | Purpose | Typical use |
|---|---|---|
| Net Portal | Connects same-named nets wirelessly | Repeated signals across schematic blocks |
| Ground symbol | Connects a node to the ground reference net | Circuit return path and ground references |
| Power/net labels or named nets | Names an electrical node | Power rails, buses, control signals |
| Connectors/terminals | Physical or logical interface pins | Off-board wiring, module boundaries, part pins |
