## Option 1 - Update Firmware using Precompiled Binaries
If you don't need/want to customize the multi module firmware then you can use pre-compiled binaries available [here](https://github.com/pascallanger/DIY-Multiprotocol-TX-Module/releases).
**STM32 Builds (file names beginning with 'Multi-STM_')
**STM32 Builds (file names beginning with 'Multi-STM_')**
- All radio modules and protocols are included in all builds
- Files with TXFLASH in the name are built with a bootloader for flashing from a transmitter OR via the module's USB port (eg. Multi-STM_TXFLASH_INV-vX.X.X.XX.bin)
- Files with FTDI in the name are built without a bootloader for flashing using an FTDI adapter (eg. Multi-STM_FTDI_INV-vX.X.X.XX.bin)

Multiprotocol firmware can be compiled and flashed with your customized firmware using the Arduino IDE. The guide below will walk you through all the steps in many details, don't be afraid by the length it is in fact simple!
### Install the Arduino IDE
1. Download and install the Arduino IDE. The currently supported Arduino version is 1.8.5, available for [Windows]( https://www.arduino.cc/download_handler.php?f=/arduino-1.8.5-windows.exe), [Mac OSX](https://www.arduino.cc/download_handler.php?f=/arduino-1.8.5-macosx.zip) and [Linux (64-bit)](https://www.arduino.cc/download_handler.php?f=/arduino-1.8.5-linux64.tar.xz)
1. Download and install the Arduino IDE. The currently supported Arduino version is 1.8.9, available for [Windows]( https://www.arduino.cc/download_handler.php?f=/arduino-1.8.9-windows.exe), [Mac OSX](https://www.arduino.cc/download_handler.php?f=/arduino-1.8.9-macosx.zip) and [Linux (64-bit)](https://www.arduino.cc/download_handler.php?f=/arduino-1.8.9-linux64.tar.xz)

### Configure the Arduino IDE
1. Under **Tools -> Board** select **Multi 4-in-1 (STM32FC103)**
1. Under **Tools -> Debug Options** select **None**
## Configure the firmware
The STM32 module has more than enough flash space for all the available protocols so, unlike the Atmega328p-based module, it is not necessary to disable unused protocols.
