This 3DR Radio Telemetry 433MHz 500mW Set allows you to link a flight controller to a USB or UART-equipped device such as a computer, laptop, or tablet supporting a USB connection (OTG).

This radio telemetry set has a separate Air & Ground module. Its transceivers can use UART or USB connections and support both modes. 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.

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.

Note: The reference to APM refers to the ArduPilot project, a family of open source autopilots based on the Arduino open-source computing platform, developed by 3DR and the open-source community. It consists of a choice of ArduPilot Mega (APM) electronics and a range of free software versions for different vehicles and is governed by an open-source creative commons license.
