The RadioMaster 4IN1 external module is a multi-protocol module that integrates CC2500, NRF24L01, A7105 and CYRF6936 RF chips. Designed for OpenTX and EdgeTX systems, the RM 4IN1 module allows the radio to connect with most mainstream protocols on the market.

RM 4IN1 is compatible with more than 70 RF protocols, including DSMX, Flysky, SFHSS, HiTec, HoTT, OMP, Radiolink, Frsky and many more.

Wireless trainer function: When used in conjunction with a suitable EdgeTX or OpenTX compatible radio such as the TX16s, TX12 or Zorro the RM 4in1 module can be used as a wireless trainer link to a student radio such as another TX16s, TX12, Zorro or any other radio capable of transmitting DSMX, Frsky or Flysky protocols.

NANO & JR Adapter: The RadioMaster 4IN1 module is a nano module by default. A JR adapter is included as standard. Support Zorro, Boxer, TX16S MKII, TX12 MKII and more.
