RadioMaster Nomad Dual 1-Watt Gemini Xrossband ExpressLRS Module

The RadioMaster Nomad Dual 1-Watt Gemini Xrossband ExpressLRS Module is a dual-band transmitter module. It operates simultaneously on 2.4GHz and 868/900MHz frequencies. It has dual 1-watt transceivers and uses the Gemini Xrossband protocol. This helps to eliminate packet loss in high-interference environments.

• Gemini Xrossband Technology: This protocol sends redundant packets across both 2.4GHz and 900MHz bands simultaneously. This ensures a stable link even if one band has heavy interference.
• High Power Output: It has twin 1W (1000mW) dual-band transceivers for long-range performance.
• Advanced Hardware: It uses dual 3rd-generation Semtech LR1121 RF chips and a dual-MCU architecture. The architecture features a main ESP32 and an auxiliary ESP32c3.
• Universal Compatibility: It includes both micro (JR) and nano module bay adapters. This makes it compatible with most radio transmitters on the market.
• Thermal Management: It has an active cooling system to maintain performance at its maximum 1W output on hot days.
• Future-Proof Packet Rates: It supports new packet rates like X150Hz Gemini and DK500 K-mode (designed for race reliability). Speeds up to 1000Hz are planned for future updates.
• Customization & Connectivity: It includes a built-in RGB light strip for status. It also supports Wi-Fi and Bluetooth for firmware updates and configuration.

• MCU: ESP32 (main) & ESP32c3 (aux, as ESP backpack).
• RF Chips: 2 x Semtech LR1121.
• Frequency Range: 2.400–2.479 GHz and 903–927 MHz (FCC) / 868 MHz (EU).
• Maximum Packet Rate: 500Hz currently; 1000Hz supported in future ExpressLRS versions.
• Minimum Refresh Rate: 50Hz.
• RF Output Power: Up to 1000mW x 2.
• Power Supply: DC 6V – 16.8V via built-in XT30 port.
• Dimensions: 80 x 45 x 40mm (without antennas).
• Weight: 87.20g (with antennas) / 71.10g (without antennas).
