3DR Radio Telemetry Kit

The 3DR Radio Telemetry Kit has a 433Mhz frequency band and Receiver sensitivity to -124 dBm. This 3dr telemetry kit allows you to link to a flight controller to a USB or UART-equipped device such as a computer, laptop or tablet supporting a USB connection (OTG).

The Radio set lets you see live data, such as live GPS position overlaid on a map, system voltage, heading, waypoint navigation and much more. The system utilizes the 433MHz band and provides a full-duplex link using HopeRF’s HM-TRP modules running custom, open-source, firmware.

Using open-source MAVlink based ground station software, you can even fly your aircraft with a joystick via your computer and update settings live! Or just use it for your DIY projects that need a wireless Serial interface. This kit offers a great low price, longer range, and superior performance. The system utilizes the 433MHz band and provides a full-duplex link using HopeRF’s HM-TRP modules running custom, open-source, firmware.
