# Radio Compatibility

The MULTI-Module is compatible with a wide range of radios but works especially well in those which support serial communication with an external module.

Radios which do not support serial mode can operate the MULTI-Module in PPM mode, which is an industry standard available on all radios with a module bay or trainer port.

{% hint style="success" %}
Using the MULTI-Module in Serial Mode is strongly recommended, if your radio supports it.
{% endhint %}

### Serial Radios

Most modern radios support serial communication with the MULTI-Module.  This includes:

* FrSky Taranis X9D, X9D+, 9XE
* FrSky Taranis Q X7
* FrSky Taranis X-Lite
* FrSky Horus X10, X10S
* FlySky TH9X
* Turnigy 9X family
* Jumper T12
* Jumper T16
* Jumper T18
* RadioMaster TX12, TX12 MK II
* RadioMaster TX16S, TX16SE, TX16 MK II
* RadioMaster Zorro

### PPM Radios

PPM mode offers the same core functionality as serial mode, but it is harder to configure the module, and typically requires custom-compiled firmware.

{% hint style="danger" %}
A MULTI-Module with a 16-position rotary selector and a bind button is required to use PPM mode.
{% endhint %}

For more information about using the MULTI-Module in PPM Mode, see the PPM Mode page.

### Radio Firmware

Radios running [erSkyTX](http://www.er9x.com/), [OpenTX](http://www.open-tx.org/), and [EdgeTX ](http://edgetx.org/)support the MULTI-Module.  The latest version of the radio firmware is always recommended.
