ESP32 Motor Driver Board for Robot Car Controller Wi-Fi Bluetooth

The OSOYOO ESP32 Motor Driver Board v1.0 is an all-in-one robot car control board that combines an ESP32-WROOM-32E module, L293DD dual H-bridge motor driver, USB-C programming, and multiple sensor interfaces on a compact 70×54mm PCB.

Everything you need to build a smart robot car is right on this single board — Wi-Fi, Bluetooth, motor control, line tracking, ultrasonic ranging, servo control, and MPU6050 motion sensing. Just connect your motors and sensors, power it with a 7-18V battery, and start coding via Arduino IDE. No additional shields, no messy wiring.

Perfect for STEM education, hobby robotics, and IoT projects.

Key Features / Bullet Points

• All-in-One Design – ESP32 MCU, L293DD motor driver, USB-C programming, and power regulation on a single 70×54mm board. No separate shields required.

• ESP32 Wireless Control – Built-in Wi-Fi 802.11 b/g/n and Bluetooth 4.2 / BLE. Control your robot from a smartphone app or over the internet.

• Dual Motor Drive – L293DD H-bridge drives two independent motor groups (left/right) with PWM speed control. Perfect for 2WD or 4WD robot cars.

• Plug-and-Play Sensor Headers – Dedicated connectors for 5-channel line tracking, ultrasonic distance sensor, IR obstacle/following, servo, and MPU6050 gyro. No soldering needed.

• Easy Programming – USB Type-C port with auto-download circuit. Program directly from Arduino IDE, ESP-IDF, or MicroPython — no manual button pressing during upload.

• Safe Debugging – Motor Power jumper lets you cut motor power during uploads and logic testing, so your robot stays still while you code.
