Digital Micro Devices S.L

eXtended Long Range System

Know us:


Digital Micro Devices was created in 1992, we design and manufacture in Spain (Europe) radio modules and electronic products with our own technology.

We are manufacturers. The electronic boards are assembled in our factory in Spain. The PCBs are of the highest quality and manufactured in Europe.

We are specialists in SMT technology and radio frequency modules in the ISM (Industrial Scientific and Medical) bands, of 169Mhz, 434Mhz, 868Mhz, 902Mhz, 960Mhz, 2.4Ghz and 5.8Ghz.

For DMD it is very important that the radio link is safe and reliable, the pilot must have security even when the RC model is far away, for this we use the best RF chips in evolved and tested designs.

A long experience in industrial electronic systems, RF modules, bidirectional transmission-reception system design in 868-902Mhz for RC airplanes and special for FPV & UAV.

Our R&D technicians are experienced aeromodelists. More than 1200h flight in FPV-UAV since 2008.

We know your needs firsthand!!!


LRS and XLRS systems history:


DMD started the manufacture and commercialization of products for radio Control and FPV in 2007, being pioneers with LRS (Long Range System) with real ranges of more than 50Km that nobody had at that time. 

Packov, Tron and Juan Carlos in the flight field at the beginning of the FPV with the LRS system.

We were very successful and LRS kits were sold everywhere. The LRS acronyms became popular all over the world.

After several years improving versions of the LRS system, we had 150Km reaches.

The LRS system it was a range extension system that needed a standard TX Radio Control.

First OSD design: OSD168.


We are known in the forums AeromodelismoVirtual_LRS and RCGroups.

Design and commercialization OSD644.

On this date the systems are directed to the new amateurs of FPV.




Improvement and redesign of the LRS product in general.



In 2010 we started the design of XLRS_D2 with a new different TX, thought for UAV and FPV professional, The XPAD2 with range up to 180Km in three versions: With Joysticks (XPAD2-RCJOY), Without Joysticks (XPAD2) and with Minijoysticks type GamePad (XPAD2-MINIJOY).

The technology was updated with a new series of microcontrollers, we created the Alpha operating system and the ACL command language, making all DMD products compatible with the new technology.

It was a tremendous effort that we are proud of.


First XPAD D2 sketches.


XVOSD2 and D2 Receivers





The LRS systems were upgraded to Version Two, changing the design.

We start to manufacture and commercialize the first XLRS_D2 systems (eXtended Long Range System D2) for professional use, integrating Radio Control and video into a single module. Range of Radio Control and Telemetry up to 180Km maximum.


New target market: Professionals and manufacturers.





In mid-2016 we started the design of the new XLRSD3, the video system XVID, Mavlink radio modem and the improvements and update of the XLRS_D2 2017.



It has been improved to range up to 200Km and the robustness of the XLRS systems.


In production XLRS D2 and XLRS D3 systems. New update soft and firmware available!!!

XVID video systems already in production.


In new design and competitive XLRS_D1 radio modems for the drone or airplane (transparent protocol and Mavlink), convertible into a receiver by only acquiring the license compatible with XLRS systems.

Design of new XLRS_D1 USB radio modem for PC with scalable ranges and convertible in base station (BTSD1) with only acquire the license. Scalable ranges up to 200Km.


We are currently expanding our network of distributors around the world.

If you want to be a distributor, please contact by mail or by chat on the web.


2018 :

Improvement and evolution of the DMDStudio,software for control and configuration of XLRS systems.


Multiple hardware improvements now more robust internally and externally and firmware evolution with bluetooth activation in XLRSD2 and D3 systems.


Design and production of the new Video Booster from 4W to 2.4Ghz, now you can have a good video range.


New and more robust RXLRS Receiver and replaces all previous receivers (RMD1, RXD2, RXD3).


New Hardware XOSDV2 and hardware upgrade RXVID2 Video receiver.


GCSD4, New Ground Control Station D4, the new jewel in the crown…





New version of XVID video system (XVID3), new analog video receiver more sensitive 10dBm than previous versions RXVID, RXVID2 and new 2.4Ghz video transmiter XOSD3W1 with 1W or 2W of power (can reach twice the distance).

XPAD4-CP, New Professional Remote Control Panel RC, ideal for integration in fixed or portable professional base stations.


GCSD4V2, New Version V2 of Ground Control Station D4.


MX433, Moxon Rectangle Antenna 400-480Mhz, 5.5dBi.


GCSD4SV2 + SMBTS, New Version V2 of Ground Control Station D4 with external radio in new Smart Antenna (SMBTS) with ethernet cable connection.


GCSD4SRV2 + SMRBTS, New Version V2 of Ground Control Station D4 with redundant external radio in new Redundant Smart Antenna (SMRBTS) with ethernet cable connection.


BQ89. New Biquad Antenna 866-920Mhz, 11-12dBi.



In design:

New system with RF systems for RC and video integrated with professional antenna Tracker and compatible with XLRS systems.

New analogs video systems of 1.2Ghz and 5.8Ghz.
