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
Sure! Since your project currently doesn't have any components or connections, I'll create a high-level block diagram structure. Let's assume we have a few common components to get started:
Here is a high-level block diagram using Mermaid syntax:

This is a simplified high-level diagram of a typical embedded system with basic components. Feel free to modify the components or specify additional ones, and I can update the diagram accordingly!
Alright! To control two DC motors using an L293D motor driver IC, you'd typically connect it to a microcontroller. Let's use the ESP32-WROOM-32 as the microcontroller. Here’s a step-by-step guide on how to connect the components:
Power Supply: 12V for motors and 5V for the driver logic
Connections:
Power Connections:
Connect the power supply positive terminal to the common power rail.
Connect the power supply negative terminal to the common ground rail.
L293D Power and Ground:
Connect Vcc1 (Pin 16) to 5V (for logic supply).
Connect Vcc2 (Pin 8) to 12V (for motor supply).
Connect GND (Pin 4, Pin 5, Pin 12, Pin 13) to the ground.
Microcontroller (ESP32-WROOM-32) to L293D:
Connect ESP32 GPIO12 to L293D IN1 (Pin 2).
Connect ESP32 GPIO13 to L293D IN2 (Pin 7).
Connect ESP32 GPIO14 to L293D IN3 (Pin 10).
Connect ESP32 GPIO27 to L293D IN4 (Pin 15).
Motor Connections:
Connect L293D OUT1 (Pin 3) to Motor1 Terminal1.
Connect L293D OUT2 (Pin 6) to Motor1 Terminal2.
Connect L293D OUT3 (Pin 11) to Motor2 Terminal1.
Connect L293D OUT4 (Pin 14) to Motor2 Terminal2.
Enable Pins:
Connect EN1 (Pin 1) to 5V (for Motor1).
Connect EN2 (Pin 9) to 5V (for Motor2).
Schematic:
Here's the textual description of the connections in the format specified:
