Setting up cloned 3DR Telemetry

3DR sells telemetry modules for APM and the Pixhawk at $100 per pair. However, cloned versions have appeared on eBay for as less as $20 a pair, but they must be set up differently than the authentic ones. In this tutorial, I’ll show you the steps to set up this module to work on OSX.

915mHz is legal in the United States, while 433mHz is legal in Europe.

First, connect the USB Telemetry to your Mac, and open the System Information application from spotlight.

Then, under the USB tab, check the information about the telemetry module.

In this case, the computer recognizes a “CP2102 USB to UART Bridge Controller,” which is common among telemetry clones. In order to get it working, we’ll have to install a specific driver for the CP2102 from its manufacturer, Silicon Labs.

Download the Mac (or your operating system) from the webpage.

Driver Link

Double click on SiLabsUSBDriverDisk.dmg and initially nothing seems to happen. Navigate to your desktop, and a new drive will be mounted.

Once finished with the installation, connect the other module of the telemetry kit to your flight controller using the DF13 cable at the Telemetry 1 port. Then, power on your quad. The green blinking light on both radios should go from blinking green to solid green, meaning that a connection has been secured. The red light will flash whenever data is transferred.



Open Mission Planner, and click on the MAVID button on the top right corner.

This will open a new window. Change the Serial Port to SLAB_USBtoUART and the Baud Rate to 57600.

Click the Connect  button, and after after a few seconds, data should start being transferred between your computer, and your drone.

Additionally, you can now monitor flight stats from your laptop, while your drone flies! And all this works at just a fraction of the cost of an authentic $100 3DR Telemetry.

    Thank you very much !!

  3. You’re a lifesaver. I had been trying to set up this identical 3DR telemetry clone on macOS but couldn’t find any link to these drivers until I found your blog. Thank you so much for taking the time to write this post!
