Atom Black Editionreleased!

The world is evolving at a breakneck pace, and we are helping it do so. To support developers, innovators, enthusiasts, and others, we have created the Atom Black Edition series.
It provides the opportunity to use our platform to develop new solutions in the world of automation or IoT.
Our devices are designed with a modular architecture giving you a possibility to choose any peripheral devices you need for your research or development.

Atom Black Edition

We have developed two types of controllers in this series to better fit your project requirements. We provide you with the ability to program for controllers stm32 and esp32, which meet the standards of stability and reliability in today's world.
This series can be used when writing your own software, as well as to use existing solutions popular in the world of automation and IoT (micropython, esphome.io, tasmota and others).
Our devices can be used by integrators, laboratories, startups, and educational institutions to train the next generation of engineers. Atom Black Edition series controllers have protection from overloads, erroneous connections and also have a custom designed case, to prevent accidental contact with electrically conductive parts.

Atom Black Edition products

Choose a controller with the necessary set of interfaces, and write the software for your needs with your own hands. No one can create the automation of your unique projects as well as you!

Changeable modules

Are you planning to automate your home, but have not yet decided what you will need to control? Do you have plans to expand the functionality of the "smart home" in the future? Do you test equipment that you replace often? Then you have the opportunity to flexibly change the type of controller outputs using our changeable modules!

i3 Network kits

Wired and wireless network interfaces are, in a nutshell, a communications standard in modern automation systems. Choose the communication interfaces based on your needs.

Optional components

Need even more features? Choose additional interface’s boards or an energy meter board that can be installed in the controller and help you to scale up your projects.

Accessories

Must have tools for the implementation of creative ideas: sets of adapters for uploading firmware into controllers based on STM32 or ESP32 processors using the USB interface.
