Modules are included in the firmware and allow users to extend the functionality of their mesh or device.
The list of current modules is as follows:
| Name | Description |
|:----:|:-----------:|
| [Range Test Module](/docs/settings/moduleconfig/range-test-module) | Send messages with GPS location at an interval to test the distance your devices can communicate. Requires (at least) one device set up as a sender and one as a receiver. The receiver(s) will log all incoming messages to a CSV. |

Once module settings are changed, a **reset** is required for them to take effect.
