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.\u003c\/p\u003e\n\u003ch2 data-id=\"Features\" id=\"features\"\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e4 x Servo Drive\u003c\/li\u003e\n\u003cli\u003eCompatible with C\/C Plus\u003c\/li\u003e\n\u003cli\u003eInterface expansion (GPIO, I2C)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 data-id=\"Includes\" id=\"includes\"\u003eIncludes\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1 x Hat CBack Driver\u003c\/li\u003e\n\u003cli\u003e2 x Hexagon Screw M2*5\u003c\/li\u003e\n\u003cli\u003e1 x Hex Key L-Shape\u003c\/li\u003e\n\u003cli\u003e1 x LEGO Compatible Connector\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 data-id=\"Applications\" id=\"applications\"\u003eApplications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eServo Controller\u003c\/li\u003e\n\u003cli\u003eRobot Control\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 data-id=\"Specifications\" id=\"specifications\"\u003eSpecifications\u003c\/h2\u003e\n\u003cdiv class=\"table-container\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eMCU\u003c\/td\u003e\n\u003ctd\u003eSTM32F030F4P6\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommunication Interface\u003c\/td\u003e\n\u003ctd\u003eI2C Communication @0x38\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWorking Current\u003c\/td\u003e\n\u003ctd\u003e15mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Size\u003c\/td\u003e\n\u003ctd\u003e23.7 x 49.2 x 21.0mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Weight\u003c\/td\u003e\n\u003ctd\u003e9.0g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage Size\u003c\/td\u003e\n\u003ctd\u003e138.0 x 93.0 x 22.0mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGross Weight\u003c\/td\u003e\n\u003ctd\u003e13.5g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eLearn and Documents\u003c\/h2\u003e\n\n  → DOCUMENTS\n\n\u003c\/div\u003e","brand":"m5stack-store","offers":[{"title":"Default Title","offer_id":44021528559675,"sku":"sil1787247007957","price":4.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0611\/6651\/8331\/files\/c-back-hat-with-servo-driver-stm32f0_1.jpg?v=1787247016","url":"https:\/\/elitechicboutique.shop\/products\/c-back-hat-with-servo-driver-stm32f0","provider":"My Store","version":"1.0","type":"link"}
