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 HAT for you.
Features
Standard Pi 40PIN GPIO extension header, supports Raspberry Pi series boards, Jetson Nano
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 servos
Reserved I2C control pins, allows to work with other control boards
Comes with Online Development Resources and manual : bit.ly/3ryoMht
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

This HAT provides 2 options for the onboard pinheader:
Servo Driver HAT: straight pinheader, same size as the Pi Zero, convenient for integration
Servo Driver HAT (B): right angle pinheader, make it possible to connect servos even when stacking up
Except pinheader, the PCB and all other function/properties are exactly the same.
