Initial Power On
Once the module and antennas are securely installed, power on your radio. The Nomad module will initialize. Refer to your radio's specific instructions for accessing the ExpressLRS menu and configuring the module settings.
Operating Instructions
Binding Process
To establish communication between your radio and receiver, a binding process is required. Typically, this involves putting both the module and the receiver into binding mode. Consult the ExpressLRS documentation or your receiver's manual for detailed binding procedures specific to your setup.
Frequency Bands and Protocols
The Nomad module operates on both 2.4GHz and 868/900MHz frequency bands. It leverages the Gemini Xrossband protocol, which enhances signal reliability by transmitting data across both bands simultaneously. This dual-band capability provides redundancy and improved performance, especially in environments with high interference.

Troubleshooting
Common Issues
If you encounter issues with your Nomad module, please refer to the instruction manual provided with the product for detailed troubleshooting steps. Common issues may include:
- Binding Failure: Ensure both the module and receiver are in binding mode and within range. Check for correct firmware versions on both devices.
- Signal Loss/Interference: Verify antenna connections and orientation. Check for local interference sources. The Nomad's Xrossband technology is designed to mitigate this, but extreme conditions may still pose challenges.
- Overheating: Ensure the module's cooling fins are clear of obstructions. Reduce output power if operating in high ambient temperatures for extended periods.
- Compatibility Issues: Confirm that your radio transmitter is compatible with the module and that the correct adapter (Micro or Nano) is being used.
