# USB Drivers

Connecting the MULTI-Module to a Windows PC requires drivers to be installed.  There are two different driver packages which may be needed.

Install both drivers if you're not sure which one you need.

## MULTI-Module (a.k.a. 'Maple') USB

The MULTI-Module (also known as 'Maple' or 'native') USB drivers are needed for MULTI-Modules which have a USB port which connects directly to the STM32 microprocessor in the MULTI-Module.

Modules which use this driver include:

* Original 'Banggood' STM32 4-in-1 modules
* iRangeX IRX4 Plus
* Jumper JP4IN1 (older version)
* Vantac MPM Lite

The easiest way to install the MULTI-Module USB drivers is to download Flash Multi, which includes an installer for the drivers.

## Silicon Labs CP210x

Some MULTI-Modules have a built-in USB-to-serial adapter.  These modules require the Silicon Labs CP210x driver to be installed.

Modules which use this driver include:

* Jumper JP4IN1 (newer version)
* Jumper JP4IN1-SE (as shipped with the T16)
* Hobby Porter JP4IN1
