M5Stack M014-B

SERVO2 is an upgraded servo driver module in the M5Stack stackable module series. It uses a PCA9685 16-channel PWM controller to simultaneously control 16 servo channels. The power input is 6–12V DC, with two SY8368AQQC chips for buck conversion. The dual-channel maximum total output power is 35W (5V / 3.5A × 2), and the single-channel maximum output power is 25W (5V / 5A). When powered by a battery base, the maximum output power is 5V / 2A. The module communicates with the host directly via I2C (default address 0x40), and the I2C address can be changed via DIP switch (0x40–0x47), meaning multiple Servo 2 modules can be stacked and used simultaneously. An onboard power switch controls the power supply to Servo 2. When driving servos, the module must be powered by an external power supply via the DC interface. When using a host controller with an AXP192 power management chip (e.g., CORE2), the M-BUS power mode must be configured as input during program initialization.
