Servo Driver HAT for Raspberry Pi, 16-Channel, 12-bit, I2C

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

• 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
• Comes with development resources and manual (examples in python like Bluetooth/WiFi remote control)

Ordering Info

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.
