Specification

1.How to connect the RadioMaster RP4TD ExpressLRS 2.4GHz Diversity Nano Receiver Board to your drone?

Connect the Receiver Board for Drone to your flight controller using a UART port for SBUS or CRSF communication, ensuring correct TX/RX alignment. Power the RadioMaster RP4TD from the flight controller’s 5V BEC or external regulator. This 2.4GHz Drone Receiver supports high-speed telemetry and control signal transmission. Confirm wiring matches your flight controller’s serial configuration in Betaflight or ExpressLRS settings.

2. How to install the Dual Antenna RC Receiver for optimal signal strength?

Mount the Dual Antenna RC Receiver with both antennas oriented at different angles—ideally 90° apart—to leverage diversity reception and reduce signal nulls. Keep antennas away from carbon fiber, metal components, and high-power electronics like ESCs or VTXs. Route them along the frame arms for maximum exposure and minimal obstruction. This setup ensures robust 2.4GHz signal performance during high-speed or acrobatic flight.

3. How to bind the Nano RC Receiver with an ExpressLRS transmitter module?

Power on the Nano RC Receiver, then initiate bind mode by holding the bind button during startup or via a switch on your transmitter. On your ExpressLRS-capable transmitter, enter bind mode through the model settings. The devices will pair automatically over 2.4GHz frequency, establishing a secure, low-latency link. A solid LED on the receiver confirms successful binding.

4. How to update the firmware on your 2.4GHz Drone Receiver?

Use the ExpressLRS Configurator tool to update the firmware: connect the Receiver Board for Drone to your computer via USB-to-UART adapter or directly if supported. Select the correct target (RadioMaster RP4TD) and flash the latest firmware version. Updating ensures access to new features, improved telemetry rates, and enhanced signal stability on the 2.4GHz Drone Receiver. Always verify power stability during flashing.

5. How to troubleshoot connection issues with the RadioMaster RP4TD Nano Receiver Board?

If the Nano RC Receiver fails to connect, verify UART wiring and ensure the correct serial port is enabled in Betaflight with CRSF or SBUS selected. Confirm the Dual Antenna RC Receiver is properly bound and powered with clean 5V. Check for physical damage to antennas or connectors, and ensure no interference from nearby RF sources. Re-flashing the latest ExpressLRS firmware often resolves persistent communication issues.
