Esmacat Master S

EtherCAT Master Hardware with Minimal Setup Time for Robotic Applications 

Retired (No Longer for Sale)

The Esmacat Master S is a powerful EtherCAT master hardware capable of running all the computing needs for most robotic applications. It comes with a pre-loaded real-time Linux OS (based on Ubuntu 18.04), along with the complete suite of the Esmacat Master software. The Master S has all of the necessary hardware to be used as a desktop PC during the development stage (including Wi-Fi, HDMI, VGA, and USB ports), but is also optimized for mounting within the final robot itself with its low power consumption, fan-less design, aluminum construction, and SSD. This 2-in-1 capability drastically improves the smoothness of transition between development, testing, & debugging, and final deployment. With the Esmacat Master software loaded as a C++ API, the Master S also offers the flexibility of easily running other custom robot algorithms on it without the need for an additional pieces of computing hardware.


Esmacat Master S now supports ROS for the EtherCAT Arduino Shield by Esmacat (EASE)!

Incorporating the Esmacat Master S Into Your Project

We have plenty of supporting material on our tutorials page such as documents and videos on how to get started with the Esmacat Master S. The Master S has all Esmacat products preloaded into the Esmacat Master Software source code but can include other non-Esmacat products with a few extra steps found in this YouTube video. 


Master Software

Esmacat provides EtherCAT master software already preloaded onto the Esmacat Master S for minimal setup time. Simply power the Master S, log in with the provided account info, build your program on QT creator or however you choose, run the program, and you are good to go!

The master software is C++ based and can be edited to fit your applications if need be.
