 ##  Description
 
-**SERVO 2** is an updated servo driver module in the M5Stack stackable module series. It uses a PCA9685 16 channel PWM controller to control 16 channel servos at the same time. The power input is 6-12V DC and two SY8368AQQC chips are used for voltage reduction. 
+**SERVO 2** is an updated servo driver module in the M5Stack stackable module series. It uses a PCA9685 16 channel PWM controller to control 16 channel servos at the same time. The power input is 6-12V DC and two SY8368AQQC chips are used for voltage reduction.
 
-The maximum total power output of dual channel is 35W (5V / 3.5A * 2), and the maximum output power of single channel is 25W (5V / 5A). When the battery base is used for power supply, the maximum output power is 5V / 2A. The module communicates with the host directly through I2C (the default address is 0x40) however the I2C address can be changed through the dial switch. This also means that multiple Servo 2 modules can be stacked and used simultaneously. There is a power switch on the board to control the power supply of Servo 2.

 ## 描述
 
-**SERVO 2** 是M5Stack堆叠模块系列中的一款舵机驱动模块，内部采用PCA9685 16通道PWM控制器，可以同时控制16路舵机。采用直流电源输入（6-12V）设计，通过两片SY8368AQQC进行降压，双通道输出最大总功率35W (5V/3.5A*2)，单通道输出最大功率25W(5V/5A)，当使用电池底座供电时最高支持5V/2A输出。模块与主机直接通过I2C进行通讯（默认0x40），通过拨码开关可改变I2C地址，这也意味着多个SERVO2可以堆叠使用，板上有一个电源切换开关，可控制SERVO2电源通断。
