4WD Smart Robot Car KIT DIY Kit with 12V Li-ion Battery and L298N Driver,ESP32

Product Overview

Experience the next level of robotics with this high-performance 4WD Smart Robot Car Training Kit. Specially engineered for advanced developers and engineering students, this kit moves beyond basic 6V hobby toys by integrating a high-torque 12V power system.

At its core is the ESP32 Dual-Core Microcontroller, providing built-in WiFi and Bluetooth connectivity for wireless control. Managed by a dedicated BMS (Battery Management System) and driven by the heavy-duty L298N Motor Driver, this platform offers the speed, power, and safety required for professional-grade autonomous projects.

Key Features & Benefits

• ESP32 Wireless Intelligence: Features the powerful ESP-WROOM-32 chip, allowing for smartphone control, web-server interfaces, and IoT integration via WiFi and Bluetooth (BLE/Classic).

• High-Torque 12V Power: Powered by a 3S (11.1V – 12.6V) Lithium-ion battery pack. This provides significantly more torque and speed than traditional 4xAA battery setups, ideal for carrying heavy sensors.

• Integrated BMS Protection: The included 3S 10A BMS protects your battery cells against overcharge, over-discharge, and short circuits, ensuring a long-lasting and safe power supply.

• Dual-Channel L298N Driver: The industrial-standard L298N H-Bridge allows for precise PWM (Pulse Width Modulation) speed control and bi-directional movement for all four motors.

• Double-Layer Modular Chassis: Laser-cut acrylic double-deck design provides maximum space for mounting the ESP32, motor drivers, battery pack, and additional sensors like Ultrasonic or LIDAR.

• Dedicated Lithium Charger: Includes a 12.6V charger designed specifically for 3S battery packs to ensure safe and efficient recharging.

Applications & Projects

• WiFi/Bluetooth Controlled RC Car: Use an Android or iOS app to steer the robot via the ESP32’s wireless signal.

• Autonomous Path Finding: Connect ultrasonic sensors or IR arrays for high-speed obstacle avoidance and line following.

• IoT Surveillance Robot: Leverage the ESP32’s processing power to add a camera module for live video streaming over a local network.

• Advanced PID Control Training: A perfect platform for learning Proportional-Integral-Derivative (PID) algorithms for smooth motor synchronization.
