This expansion board is the core controller for a dual-wheel self-balancing robot, designed to plug directly onto an Arduino UNO. It consolidates motor driving, gyroscope, ultrasound, and wireless connectivity interfaces into a single board — removing the need for a rat's nest of external modules and wiring.

Build your own self-balancing robot by connecting two motors, attaching your Arduino UNO on the back, and wiring up your preferred sensors. The programming code from Elecrow gets you started quickly.

Key Features

• Arduino UNO Compatible – Connects directly to an Arduino UNO via the back interface
• Dual Motor Interfaces – Connect two DC motors for the balancing drive wheels
• Integrated Module Interfaces – Onboard connectors for motor driver, gyroscope, ultrasound, Bluetooth, and Wi-Fi modules
• Compact Form Factor – 96 × 76mm PCB

Ideal For

• Building a DIY self-balancing robot with Arduino
• Robotics learning and PID control experimentation
• Students and makers exploring motor control and IMU-based balancing
