Keyestudio Balance Car Shield V3 for Arduino UNO R3

Build your own self-balancing robot with the Keyestudio Balance Car Shield V3, designed specifically for the Arduino UNO R3. This shield is perfect for students, educators, and hobbyists looking to explore PID control algorithms and robotic balancing.

Bluetooth app control and tuning

The shield features an onboard XBEE Bluetooth socket, allowing you to connect a smartphone app for wireless control. Through the app, you can toggle between key and gravity control modes, adjust the balance angle, and fine-tune PID parameters in real time.

High-torque motor compatibility

This board is compatible with 12V permanent magnet brushed motors featuring a 1:30 reduction ratio and 7.5kg.cm stall torque. The metal gear reduction ensures stronger horsepower, low power consumption, and quick start times.

Integrated switches and communication ports

For easy configuration, the shield integrates a dedicated power switch, an XBEE communication switch, serial communication, and I2C communication pins. It also includes a built-in active buzzer controlled via pin D11 and a button device on pin D13.

Operating voltage and current

The shield operates on a DC voltage range of 7V to 12V with an operating current of 800mA. This makes it highly compatible with standard power supplies used in Arduino UNO R3 setups.

Compact and lightweight design

Measuring just 80mm by 60mm by 28mm and weighing only 28.6g, this shield fits neatly on top of your microcontroller without adding excessive weight. It is also fully RoHS compliant.
