RadioMaster Nomad Dual 1-watt Gemini Xrossband ExpressLRS Module

Presenting the RadioMaster Nomad: the next evolution in ExpressLRS RF design! The Nomad is equipped with dual 3rd-generation Semtech LR1121 transceivers, allowing for operation with both 2.4GHz and 868/900MHz frequencies using the advanced Gemini Xrossband protocol. This technology enables the transmitter to send packets on both bands simultaneously, reducing the risk of packet loss due to interference.

With dual 1-watt dual-band transceivers, the Nomad has exceptional range and revolutionary interference rejection for demanding environments providing enhanced performance and reliability. The Nomad comes with a micro module and nano module adapter, ensuring it works with most radios on the market today.

Whether you're pushing the limits of range or flying in crowded environments, the Nomad has you covered, giving you the confidence to explore new horizons.

The DBR4 ExpressLRS receiver pairs perfectly with the Nomad and offers seamless compatibility. Together, they push the boundaries of conventional performance, delivering unmatched reliability and efficiency of Gemini-X. Click here to learn more about DBR4 receiver.

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.
