:::warning
GPIO access is fundamentally dangerous because invalid options can physically damage or destroy your hardware. Ensure that you fully understand the schematic for your particular device before trying this as we do not offer a warranty. Use at your own risk.

<PluginModule name="inputbroker_" rename="rotary1_" />

<!--- TODO add link to hardware setup to admonition--->

:::note
This module requires attaching a peripheral accessory to your device. It will not work without one.
:::

## Overview

Meshtastic supports hardwired rotary encoders as input devices.
Currently, one rotary encoder (`rotary1`) is defined, but later more rotary encoders
can be added (if needed) the same way.

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