Of course there is always a catch. In this case it is the 32KB memory limit on the ATmega328 processor. Due to the amazing work done by devs on this project, the memory required by all the possible protocols exceeds this limit considerably. This means that you will need to make a choice of which protocols you will compile into your firmware. Fortunately, the process of selecting and compiling is not too difficult and it is fully documented on the [Compiling and Programming](docs/Compiling.md) page.
Also, the lead dev Pascal Langer (rcgroups:hpnuts) makes this process even easier for many users by making compiled binaries available for three popular combinations of RF modules. These are always “fresh” (based on the latest stable firmware) and available on the [Releases](https://github.com/pascallanger/DIY-Multiprotocol-TX-Module/releases) page.
Midelic has ported a version the firmware to an STM32 ARM microcontroller. If you go the route of building this version of the DIY MULTI-Module then the memory limits do not apply anymore.
An alternatice is to use a STM32 ARM microcontroller based module. If you go the route of building this version of the DIY MULTI-Module then the memory limits do not apply anymore.
##**Choice 4:** Choosing the type of interface between the MULTI-Module and your radio (PPM or Serial)

1. A MULTI-Module based on the OrangeRx DSM transmitter module that natively supports the built in CYRF6936 RF module. This module can be improved with Mulitprotocol firmware in serial mode only:
- Now works with most (all) DSM bind-and-fly models
- Supports the Devo protocols
- Supports the J6Pro protocols
- Supports the Walkera protocols

1. A scratchbuilt MULTI-Module using perfboard, an Arduino Pro-Mini and the desired RF modules.
Unless you are handy with a soldering iron and you have access to electronic test equipment (like an oscilloscope) you should consider only Option 1. For a price of about $44 you can get everything you need, neatly assembled
