• Raspberry Pi 4 connects to the ATmega328P microcontroller, providing GPIO signals.
• ATmega328P-AU is responsible for controlling various components, including the motor driver (L293DD).
• L293DD is connected to motors, receiving control signals from the microcontroller.
• Power distribution is managed from the Raspberry Pi, providing 5V and 3.3V rails to necessary components.
• I2C Device and other interfaces are connected to the microcontroller's GPIO.
• Passive Components like resistors and capacitors are connected to the microcontroller for supporting functions.

1. Ensure the Schematic is Complete: Make sure that all components are appropriately connected and that any missing connections or errors are resolved. Double-check component values, designators, and connections.
2. Organize the Schematic Layout: Arrange components in a logical and clean layout to ensure readability. Group related components together and clearly label all sections.
3. Use Flux's Export Feature: In Flux, you can export your schematic as an image directly. Please follow these steps to export your schematic:

   • Navigate to the schematic editor.
   • Use the toolbar in Flux to find the export option. This may be under a menu or as an icon symbolizing export features.
   • Select the export format (such as PNG or PDF) for your schematic.
   • Choose the needed resolution or size if options are available.
   • Confirm and download the exported file to your desired location.

4. Verify the Output: Once exported, open the image file to ensure that all details are captured clearly and as intended. Adjust any settings in Flux and re-export if necessary.

1. Check for Updates: Ensure that Flux is up to date, as export features may be added or changed in recent updates.
2. Explore Menu Options: Look for any menu items like "File", "Export", or similar where the option might be listed. Sometimes these options are nested under other menu items like "Download" or "Print".
3. Tool Settings and Preferences: Some export features might be conditional based on settings or preferences that enable advanced features.
4. Documentation and Support: Refer to Flux's official documentation or support resources for specific instructions on exporting schematics, as this can provide the most accurate and feature-specific guidance.
5. Pro Version Inquiry: If none of these options are available, it could be a pro version feature. You might want to verify if there are any advanced features in the pro version specifically related to exporting schematics.

• Severity (S): Ranges from 1 (no effect) to 10 (catastrophic effect).
• Occurrence (O): Likelihood of occurrence, ranging from 1 (unlikely) to 10 (inevitably).
• Detectability (D): Likelihood of detecting the failure, ranging from 1 (certain detection) to 10 (impossible to detect).
• RPN: Calculated as the product of Severity, Occurrence, and Detectability.

1. Duplicate Designators:

   • There's a designator "+5V" repeated multiple times. This could be intentional for power distribution, but it's best to ensure it's consistent in naming or properties if they represent different nets.

2. Power Connections:

   • Ensure that the power and ground connections are correctly set up. For example, verify that all required components are connected to the appropriate power rails (+5V, GND).

3. Microcontroller Connections:

   • The ATMEGA328P-AU has crystal connections to $X1$ and capacitors $C1$ and $C2$. Ensure these are properly connected for the oscillator circuit.

4. Unused Pins:

   • Double-check if there are any unused pins on the microcontroller or other ICs that need to be handled (e.g., tied to ground or left floating as required).

5. Component Values:

   • Verify the component values, such as resistor and capacitor sizes, to ensure they match with your design requirements.

6. Logic Level Compatibility:

   • Ensure that there are no mismatches in voltage levels between the Raspberry Pi and connected peripherals.

7. Licensing and Exclusions:

   • Check licensing links for components and confirm BOM exclusions, such as multiple power nets marked as "Exclude from BOM".

8. I2C Connections:

   • Confirm correct connection of I2C lines between the Raspberry Pi (RPi1) and connector $J2$.

9. Motor Driver Connections:

   • The L293DD motor drivers ($U3$ and $U2$) should be correctly connected to the motors through appropriate pins, and ensure all enable and input/output pins are connected properly.
