# Firmware Updates

MULTI-Module firmware is not the same as the radio firmware, and must be updated separately.

MULTI-Module firmware updates are released regularly and updating the MULTI-Module firmware is quite straightforward.

The latest firmware can be found on the MULTI-Module Downloads site:

## Checking the Version

The MULTI-Module firmware version can be checked by looking at the **Module Status** line in the Model Setup menu on the radio.

{% hint style="info" %}
After an OpenTX radio firmware update, the radio may tell you that there is newer MULTI-Module firmware available by flashing **Module update recommended** alternately with the version number in the Module Status.
{% endhint %}

Keeping your MULTI-Module firmware up to date is strongly recommended, as updates frequently add new features and address issues.

## Update Process

In order to update your MULTI-Module you will need to download the appropriate firmware file and use one of three available methods to write the file to the module.

Updating the MULTI-Module firmware will not affect receiver bindings - any receivers which are bound to the MULTI-Module will remain bound after the update.
{% endhint %}

**Step 1:**  Download the appropriate firmware file for your MULTI-Module

In every release there are many different firmware files, each built for slightly different radio or module configurations.  See the [Firmware Files](/using-the-module/firmware-updates/firmware-files.md) page if you need help knowing which file to download.

**Step 2:** Choose an update method to flash (write) the firmware file to your MULTI-Module

There are three ways to update the firmware on your MULTI-Module.  See the dedicated [Update Methods](/using-the-module/firmware-updates/update-methods.md) page to choose the right one for you.
