C-Back HAT with Servo Driver (STM32F0)


C Back Driver Hat is a steering gear drive board designed to be compatible with the M5StickC microcontroller. It utilizes the STM32F030F4P6 control scheme and communicates with the M5StickC through the I2C communication interface.The board provides four sets of PWM steering gear drive interfaces, allowing you to connect and control up to four steering gears. The drive power for the steering gears is directly connected to the M5StickC’s internal battery, which can power commonly used steering gear models such as SG90.In addition to the steering gear drive interfaces, the C Back Driver Hat also exposes an I2C bus on top of the M5StickC. This allows for easy expansion of I2C-compatible modules and sensors. The board also provides an additional GPIO interface through STM32 expansion. This interface can be used for general logic level input/output and analog signal input reading using the built-in ADC (Analog-to-Digital Converter).C Back Driver Hat features a LEGO-compatible hole design on the back, allowing users to easily integrate the driver board into LEGO building block structures. This enables the creation of controllable structures, such as steering gear manipulators, using the M5StickC and the driver board.
