Feature:1. Onboard for Micro:bit interface, which can be directly plugged in and use, very practical2. I2C interface control, only 2 signal wires are needed to realize the servo drive3. Support up to 16 steering gears or PWM outputs, each way with 12-bit resolution (4096 levels)4. Onboard 5V voltage regulator chip, up to 3A current output, can be connected to battery power supply through VIN terminal5. Onboard standard steering gear interface, which can be connected to common steering gears such as for SG90, for MG996R, etc.6. Reserve I2C control interface for easy access to other main control boardsSpecification:Item Type: 16 Servo Driver BoardMaterial: PCBPurpose: Suitable for driving robot servos such as robotic arms or hexapod robot.Supply Voltage: 5V(power interface) or 6V~12V (VIN terminal)Servo Voltage: 5VLogic Voltage: 3.3VDriver Chip: For PCA9685Control Interface: I2CProduct Size: Approx. 65 x 36mm / 2.6 x 1.4inThrough Hole Diameter: Approx. 3mm / 0.1in.Package List:1 x 16 Servo Driver Board
