The RadioMaster 4IN1 external module is a multi-protocol module that integrates CC2500, NRF24L01, A7105 and CYRF6936 RF chips allowing it to work with over 70 RF protocols including FrSky, DSMX, Flysky, SFHSS, HiTec, HoTT, OMP, Radiolink, and many more! Designed for OpenTX and EdgeTX systems, the RM 4IN1 module allows the radio to connect with most mainstream protocols on the market.
Compatible with Nano & JR module bays.
Wireless trainer functionWhen 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.
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.
The initial module I received had very poor range and RXs that worked before with another TX would momentarily lose connection with this module. Rotor Riot support worked with me to troubleshoot the issue and eventually sent me a replacement module at no cost. The second one works great. Thanks, Rotor Riot for the great support!
Works great
I don't have many multi-protocol drones anymore, but after converting my boxes from 4in1 to ELRS internally, I needed the 4in1.
Quick on tracking & delivery!The RadioMaster 4in1 mutil protocol module is working great with my spektrum/dsm receivers!
