The Raspberry Pi Zero Dynamixel Hat its a easy to use board that allows you to connect and communicate with Dynamixel Servo Motors by using the Savage Electronics AX interface circuit, providing the half duplex communication needed by this motors, its implemented in it a voltage converter for all the signals to the Raspberry allowing a secure communication in terms of logical levels.
It also implements a TPS62143 which is a synchronous step-down DC-DC converter optimized for applications with high power density, This regulator will let you power your Raspberry directly from a battery and also provide power to your motors.Why did you make it?
A lot of people ask me if the Ax Interface was compatible with the Raspberry, SO, The easiest way it's to make a hat for all of those who want to take robotics to the next level, a Raspberry will be a very recommended upgrade to your robotics project.What makes it special?
It implements the Savage Electronics Ax Interface. Power is provided directly from a battery to the motors and the Raspberry Pi Zero. Easy to install.
