M5 Stack SERVO2 Module 16 Channels – 13.2 (PCS9685)

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 a dual-channel is 35W (5V / 3.5A * 2), and the maximum output power of a single-channel is 25W (5V / 5A). When the battery base is used for the 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.

Note: The module must use the external power supply of the 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 an input when the program is initialized.
