\"M5Stack Servo2 Module 16 Channel 13.2 PCA9685\"

The Servo2 Module 13.2 from M5Stack is a stackable module for the M5Stack Core and drives up to 16 servos. The PCA9685 PWM chip sits on the I2C bus, the address 0x40 can be changed up to 0x47 with a DIP switch, so up to eight modules can run together. The servos are supplied via XT60 with 6 to 12 V DC, two SY8368AQQC step-down converters each deliver 5 V for 8 channels.

Important: Only operate the servos via the external supply on the XT60. With Core2 and CoreS3, set the M5-Bus power to input during initialisation (cfg.output_power = false), according to M5Stack.

Recommended Accessories:

• M5Stack Basic Core ESP32 IoT Development Kit V2.7
• Waveshare Micro Servo 9G / SG90
• Waveshare High Torque Servo MG996R 10kg/cm

Features:

• 16 servo channels in 2 groups of 8
• PCA9685 PWM chip with 12 bits
• I2C address 0x40 to 0x47 via DIP switch, change the address only without supply
• Up to 8 modules stackable, each with its own supply
• Per group 5 V / 3.5 A when both groups run (35 W in total), one group alone 5 V / 5 A (25 W)
• When supplied via the battery base at most 5 V / 2 A
• Power switch on the board
• From the factory the PCA9685 also responds to address 0x70 (ALL_CALL). If this disturbs another device on the bus, clear bit 0 in register MODE1 (M5Stack)

Application Examples:

• Humanoid robots
• Robots with many joints
• Three-axis camera mount
