433Mhz 100mW Radio Telemetry Module

  1. This Radio Telemetry Module is of 433Mhz
  2. Air data rates up to 250kbps
  3. The range is approx 1 mile (1.6 Km)
  4. MAVLink protocol framing and status reporting
  5. Frequency hopping spread spectrum (FHSS)
  6. Adaptive time division multiplexing (TDM)
  7. Support for LBT and AFA
  8. Micro-USB port
  9. Adaptive flow control when used with APM
  10. Based on the HopeRF HM-TRP radio module, featuring a SiLabs Si1000 RF microcontroller.


This 433MHz 100mW Radio Telemetry Module V2 Kit is based on the 3DR Telemetry Kit and runs the same firmware on board, making it 100% compatible. This firmware used by 3D Robotics is completely open source. This is why it is available in its own version of Unmanned Tech.

The Unmanned Telemetry Kit is compatible with Ardupilot or Pixhawk-based systems and easily adds a bi-directional telemetry link between the drone and ground station. It comes with full support and warranty because it is a product that is confident in its functionality and reliability.

New and improved V2 of the Unmanned Telemetry Kit. Full features and specs are listed below, but the main feature is that both the air module and base module are now interchangeable, each fitted with a USB connector and a DF13 connector.

I also recommend buying a 6-pin to 6-pin cable as it’s easier and better than using the supplied cable when connecting to the Pixhawk.

Also check our wide range of  flight controllersDrone transmitter and receiver and other good quality drone parts .

Note: Product image may change in terms of design.


This telemetry only could use with APM compatible control board.

As we have some variations in the color of connecting cable, we will be shipping it randomly to our customers.
