 ## Description
 
 **BALA2** is short for 'Balance', like its namesake, it's the second generation product. **BALA2** is a Self Balancing Robot consist of a M5Stack Gray and two wheels(DC motors).The base uses STM32F030C8T6 as the main control, two-way encoding motor drive, built-in 1200mAh battery.This application product comes with preloaded software, a self-balance robot application.
-This Self Balancing Robot is a Two-wheeled Robot that balances vertically using a closed-loop algorithm. You can control it to walk freely through programming, or you can combine WiFi and Bluetooth to develop remote control functions. This Robot is controllable by a Smartphone device or a Transmitter. The BALA2 base contains a wealth of interfaces. In addition to the conventional PortB and PortC, it also supports 8-channel servos, of which 4 channels can be directly connected, and the remaining 4 channels need to be connected from the inside of the base. Even if you have never been in contact with the balance car program, you can quickly complete the programming and control it through UIFlow. Self Balancing robot uses data from the Accelerometer and Gyroscope to correct its orientation and position.The 2 DC driver module communicates with M5Stack Gray through I2C bus. It's default I2C address is **0x56**.
