Servo Drive Expansion Board Adapter for Micro:bit 16 Way PWM I2C Interface Module

Feature: 1. EASY OPERATION: For Micro:bit 16 way actuator drive expansion board integrated for Micro:bit interface, no additional wiring, users can directly insert the for Micro:bit, eliminating complex installation steps, making the operation very convenient 2. HIGH EFFICIENCY I2C CONTROL: The expansion board use I2C interface control, and only 2 signal lines are needed to drive the steering gear. This interface design is very practical, greatly saving the use of data lines, while improving the efficiency of data processing 3. STRONG SCALABILITY: Up to 16 servos or PWM outputs are supported, each with a resolution of 12 bits, ensuring accurate control. And reserve I2C control interface, easy access to other main control board, suitable for completing a variety of complex projects 4. STABLE POWER SUPPLY SYSTEM: Servo drive expansion board onboard 5V voltage regulator chip, output current up to 3A, stable power supply to external devices. The VIN terminal can be connected to the battery power supply, providing a rich choice of power supply 5. EXTENSIVE COMPATIBILITY: The expansion board has standard steering gear interfaces and can connect to a variety of commonly used steering gear. Whether you are a DIY enthusiast or a professional practitioner, you can choose the steering gear you need to control Specification: Item Type: Servo Drive Expansion Board Material: PCB Supply Voltage: DC 6V-12V(green terminal) or 5V(Micro USB interface) Servo Voltage: DC 5V Logic Voltage: DC 3.3V Driver Chip: PCA9685 Control Interface: I2C Features: 1. Onboard for Micro:bit interface, plug and play. 2. I2C interface control, only need 2 signal lines to drive servos. 3. Support up to 16 servos or PWM outputs, each with 12 bit resolution. 4. Onboard 5V voltage regulator chip, output up to 3A current, can be powered by battery through VIN terminal. 5. Standard servo interface onboard, compatible with commonly used servos. 6. Reserved I2C control interface for easy connection to other master boards. . Package List: 1 x Expansion Board 1 x User Manual Note: 1. If only powered by the for micro:bit USB port, the expansion board does not have a 5V power supply and cannot drive the servo motors. 2. If high power servos are connected, there may be insufficient power supply, requiring additional power sources.
