MakerFocus PWM Servo Motor Driver IIC Module 16 Channel for Raspberry Pi

Overview:
Needless to say, the Raspberry Pi is powerful enough in most cases, yet it's not that good at providing precise PWM output. You may have tried to control a robotic arm or a hexapod walker by using the Pi, but finally get frustrated due to the limited number of PWM outputs and the jittering servo. Now you get a new option to bring your ideas to life, we prepare this useful Servo Driver Board for you.

Features:
Raspberry Pi connectivity, compatible with Raspberry Pi Zero/Zero W/Zero WH/2B/3B/3B+
I2C controlled, using only 2 pins
Up to 16-Channel servo/PWM outputs, 12-bit resolution for each channel (4096 scales)
Integrates 5V regulator, up to 3A output current, can be powered from battery through VIN terminal
Standard servo interface, supports common used servo such as SG90, MG90S, MG996R, etc.
Reserved I2C control pins, allows to work with other control boards

Specifications:
Power supply: 5V (Pi connector) OR 6V~12V (VIN terminal)
Servo voltage: 5V
Logic voltage: 3.3V
Driver: PCA9685
Control interface: I2C
Dimension: 65mm x 30mm
Mounting hole size: 3.0mm
