The item is a professional and practical single TTL 3D Robotics 3DR radio telemetry kit, which is the ideal way to setup a telemetry connection between your APM and a ground station. Small, inexpensive and with great range, the 3DR radio uses an open source firmware which allows us to do things that cannot be done with other radios.
