# min-eVOLVER

## Overview

The min-eVOLVER is a minimal, mini version of the main eVOLVER. It runs in the same software ecosystem with minimal changes to the code. However, the min-eVOLVER controls two eVOLVER Smart Sleeves and six pumps, making it simpler, smaller, and less costly.

{% hint style="warning" %}
Currently the min-eVOLVER does not use the eVOLVER GUI. All experiments must be started with the command line. Sending commands without an experiment is done through [send\_command.py](/evolver/extensions/min-evolver/send_command.py.md).
