3DR Radio Telemetry 915 MHz
This 3DR 915 MHz Radio Telemetry kit set allows you to connect 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 a longer range, and offers superior performance. The system operates on the 915 MHz band and provides a full-duplex link using HopeRF’s HM-TRP modules running custom, open-source firmware.
