# Evolve

{% hint style="info" %}
A new version of Evolve is coming soon! Please note that the current version will be deprecated, so stay tuned for updates and details on the latest features and improvements.
{% endhint %}

Evolve is a highly customizable, compact, energy-efficient data collection solution. It features modular sensor ports for customizing the device to specific measurement needs and an M.2 connectivity port for flexible connectivity options. In addition, the device can be powered by various sources, such as industrial batteries or a solar panel, making it a versatile choice for remote sensing applications.
