##What you need
First you must choose the PCB onto which to solder all the components. There are two PCB options:
- ATmega (8-bit) powered PCB V2.3d supporting individual RF modules
- STM32 (32-bit) powered PCB supporting the 4-in-1 RF module
- STM32 (32-bit) powered PCB V1.0t supporting the 4-in-1 RF module
The **ATmega-based board** has been designed to accept individual RF modules. This way you can select just the module or modules you want. The downside is that each module requires its own antenna. It can become cumbersome with 4 antennas protruding from the module. It is possible to soder the 4-in-1 module to the PCB using thin insulated wire. This 4-in-1 module requires only one antenna. Finally, the Atmega board has a 32k flash memory. This is big enough to accommodate more than 15 protocols, but it cannot accommodate all the available protocols.
