Introducing the New 3DR Radio


We’re pleased to announce our new 3DR Radio. Featuring interchangeable air and ground modules (both with native USB connectors), Android tablet compatibility, and a protective case, our new radio delivers unparalleled ease of use for viewing in-flight data, changing missions on the fly, and tuning.

Quite a bit of work went into the new radio design. Our first version was simply a carrier board for the radio module, providing a power supply, an antenna connector and a way to connect to the autopilot or the computer. Our new radio provides an EMI shield over the radio module, EMI filtering chips on all power and signal lines, USB and autopilot connectivity options on the same board, and an enclosure for protection and easy mounting.

Each Telemetry Kit comes with two modules, two antennas, and cables to connect to Pixhawk, APM, PX4, laptop, and Android tablet/phones.

    It is based on the HopeRF’s HM-TRP module.



  • Dear Thomas J Coyle III

    Good Night,

    You know what is the  manufacturer and the model of  the RF Module 3DR use ? I will try to find the FCC document for it.

    Thank You

  • Jimmy, thanks.

    Steven, thanks.

    Trenton, yes but you will need to change the baud rate on your set of radios to match the rate of the GPS.

  • can i connect a GPS receiver directly to the air module? then receive the serial data from the ground module?

  • This is customer service with a smile but unfortunately, no action. I've had it so many times, I just gave up.

  • you sound so proud of yourself introducing this new item to the market.

    what you failed to do is introduce its helper, a Telemetry-Y- cable adapter 

    This Y-cable allows you to connect your telemetry and OSD to the APM telemetry port.

    by the way the previous version is still on your website

    i bought this 3DR telemetry set that you are so "pleased to announce" after being assured by the

    customer service person on the phone that the previous version of the 3DR radio wasn't discontinued.

    that purchase was made on october 30th, One day after your pleasure was made public, or not.

    today is November 27th and i am yet to receive this Y cable. Wouldn't it have been a wiser decision

    to have this cable ready the same time as the 3DR Radio, so that the Apm 2.x, the minimOSD and the 3DR radio would work together?

    Oh, and you say "Quite a bit of work went into the new radio design."

    That design is useless unless it has what will make it work for the customer.

    The small USB A to micro adapter (OTG cable) is for connecting the telemetry radio to a smart phone or tablet that is running Andropilot or Droidplanner.

    You could use the OTG cable to connect the APM to a PC/Laptop USB port and use MP to communicate with the APM just like with a standard USB cable. The APM micro USB port does not support the telemetry radios.

    Thanks Thomas, my bad - I just had a look and you're correct, there are two cables included. One 5 - 6 pin and one 6 - 6 pin. 

    What's the smaller USB cable for (with the 90 degree bend), can I connect it to the APM USB port and expect telemetry?

    I have the new telemetry radios also and the cable I received to connect the radio to the APM works fine.

    You should have received a cable with a 6 pin connector on one end and a 5 pin connector on the other end. The 6 pin connector is connected to the radio and the 5 pin connector fits in the APM telemetry connector port.

    There is also an additional 6 pin to 6 pin cable included that is probably to be used with the Pixhawk board.

    Please describe the cable that you are trying to use.
