Description Hat CBack Driver is a servo driver board compatible with M5StickC, using the STM32F030F4P6 control solution and communicating with M5StickC via the I2C interface. It provides 4 sets of PWM servo driving interfaces (the servo's driving power is directly connected to the M5StickC's internal battery, capable of driving general specification servos such as SG90). The module leads out the I2C bus from the top of StickC, and through the STM32, it also provides an additional GPIO interface for general logic level and ADC analog signal input reading. The back is designed with LEGO-compatible holes, allowing users to easily integrate this driver board into LEGO brick structures, suitable for building controllable structures such as servo robotic arms.
