KiCad PCB Design: ESP32 Robot Controller with Robustness Review

Project Overview:
I have a functional breadboard prototype of a mobile robot and I need an experienced PCB designer to convert it into a professional, production-ready PCB using KiCad. Beyond the conversion, I am looking for a professional review to suggest and implement improvements for robustness, EMI reduction, and overall reliability.

Hardware Specifications:
-MCU: Socket headers for ESP32 DevKit V1 (30-pin).
-Motor Driver: Integrated L298N logic (or equivalent H-Bridge) to drive two DC Motors.
-Power Supply: Input from 2x 18650 batteries (~8.4V).
-DC/DC step down (3A): Integrated Buck Converter circuit (use LM2596 module or better) to provide a stable 5V rail.

Connector Requirements:
-Servos (2x): 3-pin male headers (2.54mm pitch) for SG90 connection (Signal, VCC, GND).
-TFT Display (2.4" SPI): 8-pin JST-XH connector.
-DC Motors (2x): 2-pin screw terminals (Bornes) for each motor output.
-Battery Input: 1x 2-pin screw terminal (Borne).

Technical Requirements & Deliverables:
-Layout: MUST include a Solid Ground Plane on both top and bottom layers to minimize interference.
-Robustness Review: Add decoupling capacitors, flyback diodes (if not integrated), and proper trace widths for power lines.
-Documentation: Please refer to the attached pinout tables and connection diagrams for the exact wiring logic.

Required Deliverables:
1. Full KiCad project folder (Schema, PCB, and local libraries).
2. Gerber Files, Drill files, and BOM.
3. 3D STEP model of the board.
