Description:
This is a 915Mhz Radio Telemetry Kit that is based on the 3DR Telemetry kit and is 100% compatible as it runs the same firmware onboard. This firmware used by 3D Robotics is completely open-source.
The 915Mhz Radio Telemetry Kit is compatible with Ardupilot or Pixhawk-based systems and allows you to easily add a two-way telemetry connection between your drone and ground station. 915Mhz Radio Telemetry Kit is the new and improved V2 of the Unmanned Telemetry kit. The full features and specifications are listed below but the main features are that both air and ground modules are now interchangeable, and each has a USB connector and a DF13 connector.
The wiring is complete, and the independent housing is added. 915Mhz Radio Telemetry Kit is safer and more beautiful. The data transmission is more stable. 915Mhz Radio Telemetry Kit does not distinguish between the ground end and the air end. The two pieces are the same, all with USB, and a 6-pin serial port dual TTL design, don’t need to use any tools, users can upgrade firmware by themselves.
