-## DESCRIPTION
+## 描述
-The M5Stack BALA is a balance bot based on M5Stack FIRE, including a 2 DC driver module based on Mega328p which is a core chip on Arduino UNO
-You can even program The M5Stack BALA through Arduino or MicroPython with few code
+BALA是堆叠了M5Fire,以[M5Fire](https://m5stack.github.io/m5-docs/#/zh_CN/product_documents/m5stack-core/m5core_fire)做主控的平衡车应用,还包括了MEGA328为主控的2路直流电机驱动模块和两个轮子。你可以Arduino或MicroPython编程它。
-The 2 DC driver module communicates with M5Stack FIRE through I2C bus. It's default I2C address is **0x56**
+2路直流电机模块与M5Fire之间通过IIC通信,它的IIC地址是**0x56**。
