RotorLogic RM 4IN1 Module: Multi-Protocol Wireless RF for Zorro/Boxer/TX16S MKII/TX12 MKII

Discover the RotorLogic RM 4IN1 module for RadioMaster devices, a compact external unit designed to broaden your radio’s world of connectivity. This multi-protocol solution is built to feel seamless in a busy workshop or field, letting you adapt to different receivers and systems without swapping hardware.

With support for more than 70 RF protocols, the RM 4IN1 opens doors to brands and standards you may encounter in the RC world. From DSMX and Flysky to SFHSS, HiTec, HoTT, OMP, Radiolink, FrSky, and many others, you can pair your transmitter with a wide ecosystem of receivers and accessories. This breadth of compatibility is particularly valuable if you collaborate across projects, teams, or hobbyists who gravitate toward different setups.

OpenTX and EdgeTX friendly

The RM 4IN1 is designed to work cleanly with OpenTX and EdgeTX firmware on compatible radios, including popular models like the TX16S MKII, TX12 MKII, Zorro, and Boxer. When used in this way, the module can function as a flexible hub that supports cross-brand communication, helping you keep your core radio intact while expanding its reach.

Compact design with practical inclusions

By default the unit is a nano module, keeping installation and handling lightweight and straightforward. A JR adapter is included as standard, simplifying integration into current enclosures or mounts. Inside, it brings four RF chipsets together—CC2500, NRF24L01, A7105 and CYRF6936—creating a broad compatibility matrix that supports a wide range of devices and protocols.

Key capabilities

• Compatible with 70+ RF protocols, including DSMX, Flysky, SFHSS, HiTec, HoTT, OMP, Radiolink, FrSky, and more.
• Nano module by default with JR adapter included for easy integration into compatible radios.
• Supports OpenTX and EdgeTX on radios like TX16S MKII, TX12 MKII, Zorro, Boxer.
• Operational voltage supported from 4.5 to 8.4V for flexible power options.
• RF chipsets CC2500, NRF24L01, A7105 and CYRF6936 enable broad cross-brand compatibility.

Real-world use cases

• Acts as a wireless trainer link between student and teacher radios when paired with compatible devices.
• Consolidates multiple protocols into a single external module, reducing gear swaps and clutter.
• Expands cross-brand compatibility, allowing more receivers and accessories to work with your existing transmitter.

If you’re exploring more versatile control setups, the RM 4IN1 offers a flexible path without committing to a single protocol ecosystem. Consider it as a practical tool for experimentation and broader compatibility rather than a guaranteed outcome for every scenario.
