RoboCore 2.0 – ESP32-S3 Robotics Controller Board

RoboCore 2.0 is a compact all-in-one robotics controller PCB designed to reduce wiring and make robot prototyping faster and more reliable. It combines the main microcontroller, motor driver, IMU, and expansion ports on a single board, so students and hobbyists can build robots (line follower / obstacle avoidance / balancing experiments) with fewer external modules.

Why I built it

When building robot cars, most time is wasted on messy wiring: separate dev board, motor driver, IMU, sensor breakout boards, and power modules. RoboCore 2.0 brings the most common robotics blocks into one PCB to improve stability, reduce connection issues, and make projects easier to replicate.

Key Features

• ESP32-S3 as the main controller (fast MCU + wireless capability when needed)
• TB6612FNG dual motor driver for two DC motors
• MPU6050 IMU for angle / acceleration / gyro feedback (useful for balancing + motion sensing)
• TCA9548A I2C multiplexer to connect multiple I2C devices reliably
• Sensor / module headers for quick plug-in: IR sensors, ultrasonic sensor, OLED and other expansion modules
• Designed for education + prototyping (easy to assemble, easy to debug)
•
