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.
