Power net portal is a special schematic object used to define a power or ground net. Power ports allow you to conveniently indicate a power net at any location in the design. Power nets of the same designator automatically connect throughout your design #portal #power
A generic fixed inductor for rapid developing circuit topology. *You can now change the footprint and 3D model at the top level anytime you want. This is the power of #generics
Could you please clarify what specific electrical connection you'd like to create? For example, are you looking to wire particular components together, connect a power net to a component, or something else? Let me know so I can assist you better.
Below is a suggestion for wiring your schematic based on your requirements. You can use the "Apply changes" button to update the schematic with these changes.
Schematic Changes:
Power Supply and Regulation:
Battery (12V):
• Create a battery power source labeled Battery 12V. Its positive terminal provides a 12V supply.
Motor Supply:
• Connect the battery 12V directly to the L298N’s motor supply input so that the DC motors are driven by 12V.
5V Regulator:
• Add a buck converter (or a 5V version of an AMS1117, e.g. AMS1117-5.0) to step the battery’s 12V down to 5V.
• Connect the buck converter’s input to the battery 12V and its output (5V) to the ESP32-CAM’s power input.
• (Optionally, if the L298N’s logic also requires 5V, use this 5V supply for its logic as well.)
Signal Wiring between ESP32-CAM and L298N:
ESP32-CAM to L298N Logic Signals:
• Connect ESP32-CAM GPIO12 to L298N IN1.
• Connect ESP32-CAM GPIO13 to L298N IN2.
• Connect ESP32-CAM GPIO14 to L298N IN3.
• Connect ESP32-CAM GPIO15 to L298N IN4.
Grounds:
• Tie ESP32-CAM GND to L298N GND, and also connect these to the battery negative terminal.
Net Labels:
Label the 12V net from the battery.
Label and connect the 5V net from the buck converter to the ESP32-CAM’s power input (and L298N logic if needed).
If you choose to use an AMS1117 regulator, ensure it is the correct 5V version (e.g. AMS1117-5.0) rather than a 3.3V variant.
Make sure to add any necessary decoupling capacitors around the buck converter/regulator and near the power pins of the ESP32-CAM and L298N per their datasheet recommendations.
You can use the "Apply changes" button to incorporate these wiring updates into your schematic.
Below is a suggested wiring update with explicit component names and the required connections. You can use the "Apply changes" button to incorporate these updates into your schematic.

12V Battery
(Use a net label called Battery_12V)
Supplies 12V to both motor driver and buck converter
Ensure that any required decoupling capacitors are added per the datasheet recommendations for the buck converter and both the L298N and ESP32-CAM modules.
Double-check that the L298N used matches the connection points for motor supply (12V) and logic (5V), as some variants could use separate feeds.
The above schematic changes assume you add or update these components into your project. You can modify the designators if needed.
