## Description

**SERVO** is made to implement the bestest, easiest way to drive Servo motors. This M5 module will make quick work of your next Servo project!  It is able to drive mutiple Servo motors, up to 12 channels(Max load :14W) . We also added an DC input for power supplement. Through M-BUS the DC in can automatically power the M5 core at top.Servo is powered by MEGA328 communicate via I2C(0x53).

## EasyLoader

>EasyLoader is a concise and fast program writer, which has a built-in case program related to the product. It can be burned to the main control by simple steps to perform a series of function verification. Please install the corresponding driver according to the device type. M5Core host [Please click here to view the CP210X driver installation tutorial](en/arduino/arduino_development), M5StickC/V/T/ATOM series can be used without driver)
