waveshare Servo Driver Hat for Raspberry Pi 3B+ 3B 2B Zero WH Zero W Zero 16 Channel PWM Outputs 12 Bit Resolution I2C Interface

Raspberry Pi connectivity, compatible with Raspberry Pi Zero/Zero W/Zero WH/2B/3B/3B+, 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 servo such as SG90 MG90S MG996R etc.
Reserved I2C control pins allows to work with other control boards
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.
