The main program is running on an ATMEGA328p running @16MHz and 3.3V.
An [Arduino pro mini 16Mhz/5V](http://www.banggood.com/Wholesale-New-Ver-Pro-Mini-ATMEGA328-328p-5V-16MHz-Arduino-Compatible-Nano-Size-p-68534.html) powered at 3.3V (yes it works) can be used to build your own Multimodule. An Arduino Mini based on Atmega328p can also be used.

This module can be purchased [here](http://www.banggood.com/2_4G-CC2500-A7105-Flysky-Frsky-Devo-DSM2-Multiprotocol-TX-Module-With-Antenna-p-1048377.html)
If you use this module and want to enable serial mode for er9x/ersky9x/Taranis/..., you have to do [this mod](http://static.rcgroups.net/forums/attachments/4/0/8/5/8/3/a8895038-170-4in1%20module.jpg).
There are currently some hardware issues with the first version of this 4in1 module:
- A7105 RF is forced to PA mode which prevents telemetry to work. Hubsan is the only protocol using telemetry for battery voltage display.
- NRF24L01 is forced to PA mode which prevents telemetry to work. There are currently no protocols using telemetry based on this RF chip.
Based on the Deviation forum these issues will be solved in the upcoming version.
