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.
Component List and Connections:
Table
| Component | Part Name & Link | Function / Connection |
|---|---|---|
| 12V Battery | (Use a net label called Battery_12V) | Supplies 12V to both motor driver and buck converter |
| L298N Motor Driver | L298N Motor Driver | - Motor supply connected to Battery_12V - Logic supply (if required) connected to 5V net |
| Buck Converter | AMS1117-5.0 | Steps down 12V from Battery_12V to 5V |
| ESP32-CAM Module | ESP32-CAM | Receives 5V from the buck converter output and interfaces with L298N through its GPIOs |
| Common Ground | c2e41937-4268-256c-7ae9-cb8cfb60aed3 | All GND pins from ESP32-CAM, L298N, and battery negative → common ground net |
Wiring Details:
- Power Connections:
- Battery 12V Supply:
- Label the battery’s positive terminal with Battery_12V.
- Connect Battery_12V directly to the motor supply input of the L298N Motor Driver.
- Also connect Battery_12V to the input of the AMS1117-5.0 buck converter.
- Buck Converter (AMS1117-5.0):
- The output of the AMS1117-5.0 should be labeled as 5V.
- Connect this 5V net to the power input (VCC) of the ESP32-CAM.
- If the L298N’s logic also requires 5V, connect the 5V net to its logic supply as well.
- Battery 12V Supply:
- Signal Connections between ESP32-CAM and L298N:
- ESP32-CAM → L298N:
- GPIO12 (ESP32-CAM) → IN1 on L298N.
- GPIO13 (ESP32-CAM) → IN2 on L298N.
- GPIO14 (ESP32-CAM) → IN3 on L298N.
- GPIO15 (ESP32-CAM) → IN4 on L298N.
- ESP32-CAM → L298N:
- Ground Connections:
- Connect the ground (GND) pin of the ESP32-CAM, the L298N’s ground, and the battery negative terminal to a common Ground component (c2e41937-4268-256c-7ae9-cb8cfb60aed3).
Additional Notes:
- 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.
Use the "Apply changes" button to update your schematic with these wiring and component connections.
