BalaC is a DIY dual wheel balancing car kit. BalaC uses the STM32 series chip, two motor driver ICs, and is also equipped with a rechargeable replaceable battery. It incorporates a light-weight design with 360° servos. It's possible to use the UIFlow graphic interface to program the balancing car. An M5StickC is included in the package. The BalaC maintains its balance with the help of mpu6886. The real-time compensation of the servos are controlled by calculating the offset value to achieve the purpose of balancing. A LEGO compatible design allows you to change different tires. If you want to learn about PID or need an interesting programming toy product, BalaC will be a good choice

At present, there is no stock program, you will need to write the PID code by yourself.
