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.  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.     Features:  16x actuator drive channel.  2X power indicator.  I2C address adjustable.  External DC power supply input: 6-12V.  DC connector type: XT60.  Include.  1x Servo2 Module.  1x XT60 power cable(11.5cm).  Applications.  Humanoid robot.  Bioni multi joint robot.  3-axis steering gear pan tilt.     Specification:  net weight: 28g.  Gross weight: 60g.  Product Size: 54.2*54.2*13.2mm.  Package Size: 95*65*25mm
