**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(0x40 - 0x47) 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.
>The module must use the external power supply of DC interface when driving the servo. When using the AXP192 power management chip's main control (such as CORE2), the M-BUS power mode needs to be configured as input when the program is initialized.
>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.
