M5Stack C Back Driver Servo Drive Board Compatible with M5StickC/C Plus STM32

Description C Back Driver is a steering gear drive board compatible with M5StickC It adopts STM32F030F4P6 control scheme uses I2C communication interface to communicate with M5StickC and provides 4 sets of PWM steering gear drive interfaces the drive power of the steering gear is directly connected to the M5StickC The internal battery can drive general specifications of the steering gear such as SG90 etc This module leads the I2C bus at the top of StickC and provides an additional GPIO interface through STM32 expansion It can be used for general logics level and ADC analog signal input reading With the LEGAO compatible hole design on the back users can easily integrate this driver board into the LEGAO building block structure which can be used to build controllable structures such as steering gear manipulators Product Features 4 x Servo driverCompatible with C C PlusInterface expansion GPIO I2C Specifications Communication protocol I2C 0x38Working current 15mANet weight 9gGross weight 13 5gProduct size 23 7 49 2 21mmPackage size 42 40 30mmApplication Servo controllerRobot controlPackage included 1 x C Back Driver2 x Hexagonal screws M2 51 x Allen keyPin mapping M5StickCGPIO0GPIO263 3VGNDC Back DriverSDASCL3 3VGNDExample This case uses C BACK DRIVER to realize 4 channel servo control and ADC reading Please select the corresponding case program below according to the equipment you are using Arduin0StickC PlusStickCProtocolProtocol type I2CI2C Address 0
