Because of the excellent work of Deviation forum, Devo series radios (DEVO7, DEVO7E, DEVO10, DEVO8S, DEVO12S) can support many different protocols now, some of the protocols need additional 2.4 G Hz transceiver module (s). & the 3 IN 1 module is meet for this. It integrates three RF chips (CC2500, NRF24L01, A7105) in one single PCB board. It supports more than 10 different protocols, such as Frsky, Flysky, WLtoys, Hubsan, Hisky & so on.

For Devo 7e, you should connect a wire to the MCU, you can use heat tape to cover unwanted MCU pins & expose the useful one, the next soldering work will be much easier.
