FAQ
Q1: Does this module support 2.4 GHz?
Yes. The 2401.5–2481.5 MHz version is available as an optional frequency configuration.
Q2: What is the maximum transmission distance?
The source specifies up to 30 km for the standard built-in 300 mW configuration and up to 150 km with a compatible external amplifier. Actual distance depends on antenna selection, installation height, terrain, interference, and operating conditions.
Q3: Can I connect an IP camera?
Yes. The dual 100 Mbps Ethernet ports support IP camera, computer, NVR, and ground station connections.
Q4: Can it connect to a flight controller?
Yes. Supported serial interfaces include TTL and SBUS, with additional interface options depending on configuration. Verify the required pinout and interface mapping before integration.
Q5: Can multiple devices work in one network?
Yes. The system supports point-to-multipoint star networking with up to 16 nodes, subject to the selected configuration and network setup.
Q6: Which frequency version should I choose?
Select the frequency band that matches your application, antenna, RF hardware, and local spectrum regulations. The ultra-wideband 1420–1530 MHz version is intended for applications requiring a wider tuning range.
Q7: Can the module be customized?
Frequency configuration, external amplifier options, and serial interface arrangements may be customizable. Contact us to confirm availability for your project.
Important Notes
• This is an embedded wireless communication module intended for system integration, not necessarily a complete ready-to-fly drone system.
• Confirm frequency, connector type, voltage, pinout, and package contents before purchase.
• Transmission distance and throughput are dependent on real-world operating conditions.
• The buyer is responsible for ensuring compliance with local radio-frequency regulations.
