Radiomaster Nomad Gemini Xrossband Module

Description

Take your FPV experience to the next level with the RadioMaster Nomad Gemini Xrossband Module, available at Multirotors. Built for pilots who demand maximum range, exceptional signal reliability, and ultra-low latency, the Nomad represents the next generation of ExpressLRS (ELRS) technology.

Powered by dual 3rd-generation Semtech LR1121 transceivers, the Nomad supports both 2.4GHz and 868/900MHz frequency bands using the innovative Gemini Xrossband protocol. Unlike conventional RF modules, the Nomad can transmit data packets simultaneously across both frequency bands, significantly reducing the risk of packet loss caused by interference. This results in a stronger, more reliable control link, even in demanding RF environments.

Featuring dual 1W dual-band transmitters, the RadioMaster Nomad delivers outstanding long-range performance, superior signal penetration, and advanced interference rejection. Whether you’re flying long-range FPV missions, freestyle, racing, or professional UAV operations, the Nomad provides the confidence and control needed for every flight.

Designed for maximum compatibility, the module includes both a Micro Module and Nano Module Adapter, allowing it to work seamlessly with most popular transmitters supporting OpenTX and EdgeTX. Installation is quick and straightforward, making it an excellent upgrade for both experienced pilots and newcomers to the ExpressLRS ecosystem.

Whether you’re exploring extreme distances or flying in crowded environments where radio interference is common, the RadioMaster Nomad Gemini Xrossband Module delivers unmatched reliability, performance, and peace of mind.

New Packet Rates

Sub-GHz 250Hz (-111dBm)

• Speed Boost: Achieve faster packet rates with enhanced sub-GHz performance.

Sub-GHz 200Hz Full (-111dBm)

• Optimized for Mavlink: Double the packet rate of current 900 SX1276 hardware, catering specifically to Mavlink users for a more robust link and reduced interference.

Dual Band X150Hz (-112dBm)

• Gemini Mode: Experience simultaneous sub-GHz and 2.4GHz transmissions, providing robust performance and reduced interference with a packet rate of 150Hz.

Dual Band X100Hz Full (-112dBm)

• Enhanced Gemini Mode: Achieve the same dual-frequency transmission benefits at a 100Hz packet rate with full 16 channel resolution, ensuring strong and stable connectivity even in challenging environments.

Introduction of K Modes

DK500 (Coming in ExpressLRS V3.5)

• Design specifically from the ground up for lovers of speed and RC reliability.  K modes are next generation FSK modulation with built in packet repair (Forward Error Correction).  Just like FLRC D500, DK500 sends repeat packets to reduce packet loss in challenging race event environments. Coupled with a Gemini enabled Tx and Rx, nothing comes close to RC reliability.

K1000 Full SubGHs (Coming in ExpressLRS V3.5)

• Yes, you read that right, 1000Hz in the 868/900MHz Domain! While this mode has been designed for maximum data throughput when used with MAVLink, don’t be fooled by the 1000Hz, during development it was tested it at long range.
