The Keyes Balance Car Shield Motor Driver Board is an expansion board based on the Arduino development platform, specifically designed for balance car projects. It features the L298P motor driver chip from LGS, a high-performance chip capable of driving two DC motors with a maximum current output of 2A. Additionally, it integrates the MPU6050 chip, which includes a Digital Motion Processor (DMP) and communicates data through the I2C interface, providing attitude calculation data to help maintain balance.
