Transparent Data Link + Radio Control. 15-30Km

Transmitter BTSD1 and RXD1 Receiver.

Professional system prepared for all types of applications FPV with 500mW RF Power and -110dBm of sensitivity to work between 15-30Km (LOS) and with a maximum range of 100km.

It can work at same time with Transparent Data Link (For transparent communication or with autopilots with Mavlink protocol: Pixhawk, APM or similar) and Radio Control (Compatible with any standard RC transmitter connected to through the trainer port).

Two options available for free ISM band 863-950Mhz or 433Mhz.

RC and Data Link data are secure with the AES128 encryption algorithm.

Version V2 2020: Now by default XLRS_D1 V2 it already has Radio Control, Transparent Data Link / Mavlink Telemetry and AES128 Encryption, we have added a new RXD1 receiver without mixes, the mixes is done on the RC transmitter, we have also changed the orientation of the product by modifying some characteristics of the XLRS radio so that the D1 system is used in 15-30Km(LOS) applications and improving the final price of the product.

Preconfigured for normative CE (Europe), FCC (America), ETA (India), 433Mhz or Custom.


We have updated the product orientation, previously the XLRS_D1 V1 had many variants and one of the main objectives was the long range of the radio system with configurations to reach up to 200km.

The product had many variants in the purchase configuration and made it difficult to choose the product, the XLRS_D1 V1 worked as: Radio Control, Data Link, Search System and / or Encryption AES128, these options worked at the same time or individually.

Now the XLRS_D1 V2, has include by default the Radio Control, Data Link and AES128 Encryption, is more oriented to professional work with ranges of between 15 and 30Km with the integrated antennas. Of course if you change the antennas you can reach up to 100km but it will be much better and easier to choose any other product that is more prepared for larger jobs, we have also eliminated the search system and by changing the specifications of the XLRS radio module and including all the functions that version 1 previously had, we have been able to improve the price.

Transparent Data Link (Mavlink Telemetry)

Autopilots and Software Mavlink

Transparent Data Link

PC to Uc, Arduino, Raspberrypi…

Transparent Data Link

PC to PC


With Mavlink protocol and transparent protocol.

On the ground BTSD1 Transmitter sends and receives data via USB or COM5 (TTL 3.3V serial port).

It is compatible with Mission Planner, QGroundControl, DMD_Studio, Terminal Serial Port, etc.

In the vehicle connect the “MODEM” port (GND,TX,RX) of RXD1 receiver to the “TELEM” port of the autopilot (Pixhawk, APM…) or the data port of another device (UC, Arduino, Raspberry…).

Example wiring diagrams: PC to PC and PC to Uc.



Connect the trainer port of your standard RC Transmitter (Futaba, Hitec, Spektrum, Sanwa, Tactic…) to the SPPM input of the BTSD1 and will automatically detect the Joysticks and channels of the RC transmitter, then the BTSD1 transmitter sending them to the RXD1 receiver where will be activated the ports of 8 servos of which one of them can be series output of up to 13 SPPM servos to connect with the autopilot or using a channel extender or signal converter module (SBUS-PPM-PWM) to obtain maximum up to 16CH.

The mixes are performed on the standar RC transmitter.

BTSD1 is powered through the USB port at 5V but also if you need it you can use a DC-DC converter and feed through its RC transmitter or using an external battery.

The XLRS_D1 system is compatible with any RC vehicle: UAV, Drone, Car, Boat, Robot, etc… for ground vehicles the distance will change depending on the conditions and antennas.

Radio Control Receiver RXD1


Radio Control Receiver up to 100Km or more depending on antennas and installtion, with Mavlink Telemetry and transparent radio modem of 38.4kb to 100kb.

Control 16 servos distributed between 8 PPM outputs and 1 SPPM configurable output of 8 to 16 servos.

The system uses AES 128 encrytion, if encryption is enabled the radio system uses it in all data packets regardless of type.

The Radio Control information and the data of the radiomodem (Data Link Transparent) or Mavlink Telemetry are encrypted using this algorithm.
