Radiomaster Nomad Dual 1-watt Gemini Xrossband ExpressLRS Module

Introducing the RadioMaster Nomad – the next generation of ExpressLRS RF design! The Nomad is equipped with two third-generation Semtech LR1121 transceivers, allowing operation in both 2.4 GHz and 868/900 MHz frequencies using advanced Gemini Xrossband technology. This technology allows the transmitter to transmit signals in both frequency bands simultaneously, thereby reducing the risk of packet loss due to interference.

Dual 1W dual-frequency transceivers deliver exceptional range and revolutionary interference suppression in even the most challenging environments, delivering unmatched performance and reliability. Comes with a micro module and nano module adapter, making it compatible with most radio transmitters on the market today.

Whether you're aiming for maximum range or flying in densely populated spaces, Nomad will keep you connected and give you the confidence to explore new horizons.

The DBR4 ExpressLRS receiver pairs perfectly with the Nomad for seamless compatibility. Together, they push the boundaries of conventional performance to deliver the unmatched reliability and efficiency of Gemini-X.

New packet transmission frequencies:

Sub-GHz 250Hz (-111dBm)
• Speed Boost: Faster packet transmission with improved sub-GHz performance.

Sub-GHz 200Hz Full (-111dBm)
• Optimized for Mavlink users: Twice the packet transmission rate than the current 900 SX1276 hardware, ensuring a more stable connection and less interference.

Dual frequency X150Hz (-112dBm)
• Gemini Mode: Transmits simultaneously on both sub-GHz and 2.4 GHz, providing greater stability and lower interference levels with a 150Hz packet rate.

Dual frequency X100Hz Full (-112dBm)
• Enhanced Gemini Mode: The same benefits of dual-frequency transmission with a 100Hz burst rate and full 16-channel resolution, ensuring strong and stable communication even in challenging environments.

Introducing K-modes:

DK500 (Will come with ExpressLRS V3.5)
• Built from the ground up for those who value speed and reliable RC communication. K-modes are a next-generation FSK modulation with integrated Forward Error Correction. Like the FLRC D500, the DK500 sends retransmitted packets to reduce packet loss in challenging racing environments. When used with Gemini-enabled transmitters and receivers, RC communication reliability becomes unparalleled.

K1000 Full SubGHz (Will come with ExpressLRS V3.5)
• Yes, you read that right – 1000Hz – in the 868/900MHz frequency range! This mode was designed to maximize data throughput when using MAVLink, but its capabilities are not limited to that. Despite the 1000Hz frequency, it has also been successfully tested in long-distance communication conditions.
