3DR Radio Telemetry 433MHz 500mW(X6)

This set of 3DR Radio Telemetry 433MHz 500mW allows you to establish a connection between a flight controller and a USB or UART enabled device, such as a computer, laptop, or tablet with USB compatibility (OTG).

The latest version 2 radios no longer require a separate Air/Ground module, as both transceivers can now use both UART or USB connections, and support both modes. This radio set not only allows you to view real-time data, such as live GPS position overlaid on a map, system voltage, heading, waypoint navigation, and even an artificial horizon, but also offers much more.

By using an open-source MAVlink based ground station software, you can even fly your aircraft with a joystick via your computer and update settings in real-time. Alternatively, you can use it for your DIY projects that require a wireless Serial interface. This kit is cost-effective, has longer range, and offers superior performance. The system operates on the 433MHz band and provides a full-duplex link using HopeRF’s HM-TRP modules running custom, open-source firmware.

1.What is 433 MHz band used for?

  • 433MHz is a commonly used frequency band for low-power equipment such as garage door openers, headphones, baby phones, and remote controls. The 433MHz band is also used by many low-cost transmitters and receivers for switching devices and light dimmers.

2.What is 3DR radio telemetry?

  • The 3dr telemetry kit connects a flight controller to a USB or UART-equipped device, such as a computer, laptop, or tablet with a USB port (OTG). The Radio set displays real-time data such as GPS position overlaid on a map, system voltage, heading, waypoint navigation, and much more.

3. Does the latest version of 3DR Radio Telemetry 433MHz require a separate Air/Ground module?

No, the latest version 2 radios do not require a separate Air/Ground module. Both transceivers can use both UART and USB connections and support both modes.


4. Can I adjust the output power of 3DR Radio Telemetry 433MHz?

Yes, the system allows you to adjust the output power up to 500mW, providing flexibility based on your communication needs and regulatory requirements.


5. Can I use 3DR Radio Telemetry 433MHz for long-range applications?

Yes, the system is designed to offer longer range communication capabilities compared to traditional methods, making it suitable for applications requiring extended distances between devices.
