Important notice:

OpenLRS is not a plug and play long range RC. You need basic Arduino experience for using and modifying our opensource platform. The Tx and Rx modules coming as pairs and you can plug and fly, but we are highly recommend to customize them for your requirements.
Visit our forum for detailed informations and questions. 

 

OpenLRS M3 Tx Module is an open source transmitter module that is configurable for any channel (400-460mhz) or any protocol or extra features as telemetry receiver of OpenLRS Rx module.

 

The module includes 1000mW (1W) RFM23BP RF unit and Atmega328 processor with Arduino Bootloader.

You can upload our codes or write your own for your custom purposes transmitter.

 

 

OpenLRS M3 module including TracoPower DC/DC ceonverter for better thermal stability and wide voltage range. 
 

 

 

Frequency Hopping or What You Want

Our original code does 3 channel frequency hopping (not FHSS, FH only) for reducing the risks.  Standard refresh rate is same with your transmitter (50hz), if one of the channels disables by an external source refresh rate reducing to %66 (33hz) , if you loose 2 of 3 channels you can still fly with %33 (15hz) refresh rate.

If you didnt like it, you can write your own hopping codes or just use 1 solid channel.

 

 

Our TX module including:

  • New! 3.3v FTDI support for easy programming
  • New! U.F.L connector between PCB and antrenna

Important!

 
Never turn on your Dragon Link Transmitter without the antenna Attached or included Dummy Load attached, this can burn it out !!!   To do your range check before flying, use the supplied dummy load in place of the transmitters antenna.  For more detailed instructions on how do to a Range Check, follow this LINK.
 
Do not over tighten the antenna on the Transmitter, this can cause the SMA connector on the transmitter to strip its threads, loosen, break, or wear out very quickly over time.  Screw on the Dragon Link transmitter antenna until it stops turning.  Do NOT tighten it down !!!   Once the antenna is snug, the connection is fully made, tightening the antenna any more will NOT increase performance !!!
 

 

  • Never turn on your Tx without the antenna attached, this can burn it out !!! 
  • Don't supply with higher voltage than 15volt.   
  • Follow our forum pages and new firmware updates remember it is opensource project and it will be better with your ideas and codes.
